3-Way Speakers


ALTO III C



alto3c

The ALTO III c has been designed as a 3-way column speaker with an inside volume of no less than 55 litres. The twin bass arrangement using two W 170 S - 8 Ohm drivers in parallel guarantees very powerful low-ranging bass reproduction, that comes across crisply and impressively even with hard-hitting beat.

From around 450 Hz upwards, the 10 cm mid-range cone W 100 S - 4 Ohm takes over, mounted in its 3 litre enclosure. Single instruments and solo voices are reproduced throughout the mid-range in a most tangible, crisp fashion, where the precise definition of virtual sound sources and their associated range layering, so typical for good mid-range cones, comes across well.

Above about 3500 Hz, the sound character is rounded off neatly by the crisp 19 mm tweeter DT 94 - 8 Ohm. The exuberance demonstrated by the ALTO III c promises to put listeners in a good mood and keep them there for several hours of musical pleasure.

ATLANTIS MK II



atlantis

The ATLANTIS has been consistently designed for optimum sound-pressure rating while retaining a moderately sized cabinet and an elegant appearance. In the bass range, two AL 170 - 8 OHM are mounted in parallel but in separate housings, where each has about 27 l of air space to itself. These speakers have a lower limiting frequency of 28 Hz meaning that they generate good, solid deep bass. Where you position the speakers is more or less a matter of choice, but they should not be right against the wall (a minimum of 10 cm is needed) as otherwise the effect of the bass reflex tubes will suffer.

Compared with the 'normal' AL 130 - 8 OHM, the AL 130 M - 8 OHM is equipped with a shorter voice coil. This improves efficiency and makes it the ideal choice in this combination.

Used as a tweeter, the KE 25 SC - 8 Ohm is activated from 2500 Hz. The distortion factor of this ceramic dome driver is really low at these frequencies, so that even high volume levels come across completely free of distortion.

CASABLANCA III



casablancaiii

The first thing one notices about the CASABLANCA III cabinet is its striking design. This cabinet shape, however, has more than just eye-catching qualities, its acoustic qualities have to be heard to be believed.
The speaker consists of a large lower chamber and a top-mounted upper chamber and the two are interconnected through an opening that has been exactly calculated. This is, in fact, a twin-chamber vented cabinet. As a result of the twin-chamber arrangement, it is possible, in comparison with a conventional vented cabinet, to extend the range downwards by a considerable amount. The Helmholtz resonance of the upper chamber is around 90 Hz, that of the lower chamber around 33 Hz.
The fibre glass high-end GF 200 - 2 x 4 Ohm woofer has been used in the CASABLANCA III and helps achieve unbelievably low-range bass levels and, at the same time, producing remarkable maximum volume levels for a speaker of this size. The two tried-and-tested "softening" textile dome units G 50 FFL - 8 Ohm and G 25 FFL - 8 Ohm guarantee transparent, rounded sound qualities across the entire mid- and high-range. The convex cones also blend in well with the overall design of the CASABLANCA III model. The result is an unusual speaker both as regards its design and its construction principles with excellent low-range bass reproduction coupled with tremendous signal fidelity.

CASABLANCA MK IV



casablanca_iv

The first thing one notices about the CASABLANCA IV cabinet is its striking design. This cabinet shape, however, has more than just eye-catching qualities, its acoustic qualities have to be heard to be believed.

The speaker consists of a large lower chamber and a top-mounted upper chamber and the two are interconnected through an opening that has been exactly calculated. This is, in fact, a twin-chamber bass reflex cabinet. As a result of the twin-chamber arrangement, it is possible, in comparison with a conventional bass reflex cabinet, to extend the range downwards by a considerable amount. The Helmholtz resonance of the upper chamber is around 90 Hz, that of the lower chamber around 33 Hz.

The woofer in the CASABLANCA IV is the AL 200 - 8 OHM, which is so popular among connoisseurs of high-end technology. Thanks to its long-stroke woofer, the AL 200 - 8 OHM helps the CASABLANCA IV achieve unbelievably low-range bass levels and, at the same time, producing remarkable maximum volume levels for a speaker of this size. Another "first" in this model is the two tried-and-tested DSM 50 FFL - 8 OHM and DSM 25 FFL - 8 OHM titanium dome units, that guarantee transparent, rounded sound qualities across the entire mid- and high-range.

Results: The result is an unusual speaker both as regards its design and its construction principles with excellent low-range bass reproduction coupled with tremendous signal fidelity.

CLASSIC 200



classic200

As the name CLASSIC 200 suggests, this speaker design uses the classic 3-band arrangement: one woofer, one mid-range cone and one dome tweeter, all arranged one above the other close together in the front baffle. The AL 200 - 8 Ohm, TI 100 - 8 Ohm and KE 25 SC - 8 Ohm used here are the best drivers in their respective categories available from the VISATON catalogue. For an upright cabinet, this is relatively small, enabling space-saving use in almost any sitting room.

The sensitivity of the CLASSIC 200 is excellent for a speaker of this size. This is made possible by the "slim-line" bass tuning. In comparison with the VOX 200, which has almost the same driver arrangement, the lower limiting frequency has been set slightly higher. This will appeal in particular to those who appreciate more "crisp" bass reproduction. The difference is that, in the CLASSIC 200, the low-frequency room resonance which is almost always present in any room, is not excited to the same degree and this reduces the reverberation.

The other drivers are also without doubt excellent and contribute to a holistic overall sound consisting of precise mid-range and clear as crystal, unobtrusive, smooth-as-silk treble frequencies.

CLASSIC 200 GF



classic200gf

Visaton's CLASSIC 200 GF offers an interesting way to enter the world of high-end music pleasure. The high-quality components have been selected with an eye on optimising value-for-money but without losing sight (or rather, sound) of the key quality requirements.

Supported by the front bass reflex vent, the GF 200 - 2 x 4 Ohm generates low-frequency sound in a classic 3-band combination. Thanks to the extremely rigid fibre-glass diaphragm and long cone-displacement properties, level accuracy is perfectly maintained even when cone excursion is considerable.

In the mid-range, the TI 100 - 8 Ohm, one of the best Visaton drivers available, takes control. This very light, rigid titanium driver has become a reference point in terms of distortion free, well-detailed music reproduction.

Above 2200 Hz, the G 20 SC - 8 Ohm fabric dome driver cuts in and does not stop until well above the frequencies considered to be audible (30 kHz).

The overall result is a very high-quality, perfectly balanced speaker whose moderate size makes it an excellent candidate for enjoying high-end music in the sitting-room.

CONCORDE MK III



concorde

The CONCORDE MK III 3-way system may not be able to fly, but in terms of sound, it really soars. The mere shape and the drivers used give an idea of its qualities. The tailored baffle in the medium to high-frequency range produces optimised omnidirectional sound distribution one of the reasons why the sound distribution throughout the room is so smooth. Arranging all the drivers according to the D'Appolito principle, reduces interference from floor and ceiling reflection. Two AL 200 - 8 Ohm aluminium bass drivers join forces to produce profound and yet precise bass reproduction thanks to the extra-large, flow-optimised bass reflex tube. The two AL 130 - 8 Ohm mid-range speakers guarantee crisp mid-range sounds as a result of their stiff cones, long stroke and impedance control ring.

At the top end of the frequency range we have used the innovative KE 25 SC - 8 Ohm ceramic tweeter, which has been incorporated using a sophisticated crossover arrangement to optimise timing. This sophisticated design of tweeter can be wired up to blend in from a very low level and, as with all the other drivers, produces extremely distortion-free sound even at high volume settings. Any defects in the source signal are laid wide open. Even at louder settings, listening to music remains a real pleasure. This is always a good sign that the baffle is working correctly and that nothing is being smuggled in that should not be there.

In the MK III version, the cut-off frequency between the low- and mid-range has been shifted from 500 Hz to 300 Hz. The filter of the tweeter has been changed to 18 dB/oct additionally. That causes a more evenly sound radiation at different angels. This is especially noticeable in less damped rooms.

The completely neutral tonality and the remarkable dynamic characteristics of this stand-up CONCORDE MK III cabinet make it an all-round talent for discerning listeners of all types of music.

CONGA



conga

With its CONGA Visaton has produced a "big brother" to accompany the classic 3-band combinations such as the CLASSIC 200 or CLASSIC 200 GF. With a cabinet volume of 85 litres and the 25-cm subwoofer drivers mounted on the front, this column speaker is an impressive eye-catcher.

The external appearance is underlined by the solid bass foundations provided by the TIW 250 XS - 8 OHM. This high-end woofer masters the art of powerful, responsive surges of bass just as efficiently as more restrained and subtle bass accompaniment.

The AL 130 M - 8 OHM, the specially modified version of the popular AL 130 - 8 OHM designed to produce higher sensitivity in the mid-range, continues the virtually linear frequency response seamlessly at a high level.

The KE 25 SC - 8 OHM tweeter, which cuts in at 3500 Hz, has no difficulty at all producing brilliant, crystal clear treble, even at high volume levels, which is why this ceramic dome driver is so ideally suited to rounding off the upper end of this powerful 3-band combination.

Well aware that the following statement may polarise opinions: the CONGA speakers are real men's speakers.

CT CENTER 81



center80_solo

The CT CENTER 81 is a compact, enclosed 3-way system with well-balanced sound quality and complete magnetic shielding, as required for example if positioned close to a TV or PC. Inside the cabinet, we use magnetically shielded speakers, types F 8 SC - 8 Ohm (8 cm full-range) and SC 5 - 8 Ohm (10 mm tweeter) and the complete speaker then meets the shielding requirements of the THX® regulations (3-Gaussian curve). The asymmetric design of the front baffle and of the crossover unit provide good omnidirectional sound distribution both vertically and horizontally. It is possible to install the speakers in the upright position, as is usual for multimedia systems, or lying down on top of a TV, as is usual with surround systems.

In terms of sound quality, the CT CENTER 81 produces clear-cut sound, well removed from the speakers, but with remarkably well-formed bass reproduction for a system of this size.

ELEVATION 3



elevation3

This designer speaker cabinet is a challenge for any experienced craftsman who is looking for a speaker that stands out from the crowd. The excellent design means that the shape is not just a designer's whim but a technically thought-out reality. The front baffle has been kept as narrow as possible all the way along. This projects the sound away from the speakers into the room, in such a way that the instruments and voices are perfectly positioned and - provided the speakers are positioned away from the walls - the listener is treated to excellent spatial sound. The curved shape of the side panels has a stiffening effect and reduces resonance dramatically. In this way, the conventional reinforcements are not required.
In the bass department, we have the GF 200 - 2 x 4 Ohm with its high level accuracy, which can really make the most of its long-stroke voice coil and fibre-glass reinforced cone. The bass driver is positioned very close to the floor of the cabinet, and requires a low cross-over frequency up to the mid-range. In order to maintain the excellent level accuracy here, a speaker with a large cone surface area has been chosen. In this combination, the AL 170 - 8 Ohm demonstrates its remarkable mid-range characteristics that guarantee exceptional transparency and clarity of sound. The tried-and-tested G 25 FFL - 8 Ohm textile dome unit adds depth and vitality to the high-range.
Not available as a complete kit.

EXPERIENCE V 20



experiencev20

The EXPERIENCE V 20 is a 96 litre vented cabinet and features a baffle arrangement based on the D'Appolito principle arranged symmetrically around the tweeter. In order to suppress any unwanted interference by the front baffle on the radiation pattern, the entire mid- to high-range unit is not positioned in the middle of the cabinet, but towards the inner side.

The woofers in the EXPERIENCE V 20 are two W 200 S - 8 Ohm 's in parallel up to around 450 Hz. From here, the mid-bass unit takes over. The W 130 S - 8 Ohm 's, also connected in parallel, cover the mid-range frequencies up to around 3000 Hz and hand over to the G 25 FFL - 8 Ohm textile dome unit at the high-range.

The crossover unit is designed for bi-wiring.

The very first impression you get of this V 20 speaker system will demonstrate the unrestricted exuberance the speakers are capable of. At the lower octave levels, the two 20 cm woofers produce crisp bass sounds with a dynamic punch that is unusual for speakers of this size. The mid-range produces absolutely linear, undistorted sound and the overall effect is of tangible sounds, spatially separated from the speakers themselves. The crystal clear, airy high-range reproduction from the 25 mm textile dome unit puts the final touch to the upper frequency end.

FIESTA 25



fiesta25

The strength of horn speakers is, without doubt, in their dynamism. Even short, extremely high peaks and sustained high volumes are reproduced without effort because horns are able to convert electrical energy into sound energy very efficiently. In many cases, this benefit is impaired by the fact that the sound is slightly distorted. This is not the case with the FIESTA 25. Emphasis has been placed in this development on achieving a frequency response curve which is as linear as possible - a key requirement for undistorted sound reproduction and a joy to listen to even if the listening session carries on into the small hours. In order to keep the cabinet down to a reasonable size for living rooms, the bass department does without a tube and instead uses large diaphragms in twin W 250 S - 8 Ohm in a closed compartment.

The striking feature of the FIESTA 25 is the mid-range horn. Here, the DK 8 P - 100 V/15 W horn speaker, based on the pressure chamber principle and borrowed from the public address department, has been applied as a low-impedance version (without the 100 V transformer). It differs from the many other horn speakers of this type which are available on the market by its remarkably good characteristics in the mid-range from 500 to 5000 Hz. Consequently, it is only applied within this range. The tweeter is the HTH 8.7 - 8 Ohm constant directivity horn which has already proved its worth in the MB 208/H kit proposal.

This unusual combination being rather quirky, it was necessary to devise a smart crossover design to achieve the high demands placed on the speaker and satisfy even HiFi standards. Even though the frequency response cannot be as linear as it would be with other loudspeakers, the listener is rewarded with remarkably good sound quality. The FIESTA 25 has a pleasant sound ranging from low bass through the clear, well-defined mid-range up to the finest of the higher frequencies. In contrast to standard HiFi speakers, however, this one can easily produce extremely high peak levels and is quite happy to make the walls bulge with continuous, high-level volumes. Provided the listener takes up a suitable central sitting position between the speakers, the well-controlled directivity of these tightly bundled horn speakers allows well-recorded sound to be easily located while ensuring good range layering.

It is fair to say, then that this is a HiFi speaker which will provide very high levels of satisfaction.

LA BELLE



la_belle

The basic concept, as simple as it was ambitious, that lay behind the creation of the La Belle speaker was to define a perfect speaker system with no measurable or audible weak points in any test discipline and that would, as a result, ensure maximum listening pleasure in any room and with any music. To achieve this aim, a number of factors had to be taken into consideration, the most important of which were linear frequency response along the axes and across a certain angle coupled with minimum distortion, even for higher dynamic peaks.

A crucial factor in this respect is the choice of the right drivers. To obtain supreme large-signal behaviour in the bass it is necessary to provide an expansive diaphragm area in connection with long cone strokes. In this respect, there was no real alternative but to opt for the extremely long-excursion TIW 200 XS - 8 Ohm driver. Mounted as a pair, these two woofers on each side even out-do the TIW 300 - 8 Ohm, and have the added advantage that they require less space and thus enable the speaker columns to be built as a remarkably slim unit with the bass drivers in the front panel.

Thanks to the absolutely inexhaustible volume reserves inherent in these woofers and the specially adapted crossover, it was possible to dispense with a bass reflex arrangement to limit cone excursion. La Belle's base is, as a result, even more precise and clear and, depending on the room, go even further down the bass frequency scale than you would expect of conventional bass reflex speakers. To cater to dynamic mid-range frequencies with adequate diaphragm area there could be no better choice than the B 200 - 6 Ohm. Originally designed as a full-range driver, the B 200 - 8 Ohm boasts minimum mechanical losses and a light-footed, responsive mid-range. Protected against overly long cone excursions in the bass range and supported at the upper end of the frequency range by the tried-and-tested KE 25 SC - 8 Ohm ceramic dome driver, the B 200 - 6 Ohm in this combination excels itself and leaves nothing to be desired.

The tweeter, in cooperation with the Waveguide WG 220x150, displays qualities undreamed-of. Thanks to its optimised directivity, the ceramic dome driver in the Waveguide can ideally by linked to the large mid-range driver, which ensures an absolutely homogeneous, seamless unit. Even at the crossover between the mid-range driver to the woofers, there is no gap in the beaming effect, which is why the frequency response for the entire speaker unit is wonderfully linear not only along the axes but also at various angles. In addition, the separating frequencies have been selected in such a way that each branch covers a similar band of frequencies, which minimises annoying intermodulation distortion.

A listening test will confirm that this concept is an unqualified success - in creating La Belle, we have made a loudspeaker that has not the slightest weak point and reproduces any musical material with such authenticity and accuracy that one soon gives up trying to detect a flaw and just enjoys the music at a quality level as yet unknown.

The peculiarities of the individual room are far less significant than with most other loudspeakers. Thanks to its steady directivity, La Belle sounds equally as good in heavily damped rooms as in poorly damped, modern living environments. The good, solid deep bass is not excessive in smaller rooms thanks to the enclosed compartments but, on the other hand, is not inhibited by large rooms and high volume levels and is happy to descend into the deepest of low-frequency regions. Finest-quality high and medium frequencies combine to create a virtual stage which is presented to the listener as firm as if cut in stone and well differentiated, irrespective of the pitch. La Belle's special fascination is in the extremely broad dynamic range covered. Even at very low volume levels, it projects instruments and voices realistically and tangibly into the listening room and yet retains such a degree of lightness and fidelity, even at very loud volumes beyond the threshold of pain, that listening to is not wearing.

La Belle is, then, definitely the recommendation for demanding listeners who wish to rediscover their entire music collection and do not want to have limits imposed on them by the loudspeakers.

LA BELLE CENTER



la_belle_center

The objective during the development of the La Belle center speaker was to convey the outstanding sound quality requirements achieved in the La Belle column speaker to a horizontal center speaker. A key aim of the project was for the center speaker to emulate its big sister’s abilities in every discipline and enable perfect integration in a high-quality surround system at benchmark level. To achieve this high standard, the configuration and volume of the housing were retained and any changes to the crossover were kept to an absolute minimum.

One particular new feature that has been incorporated is a regulator allowing the bass level to be adjusted by very fine degrees over a broad level range. This takes account of the fact that centre speakers are often mounted close to a wall and this often leads to unpleasant over-emphasis of bass frequencies. To achieve even better freedom as regards the distance above the floor, the control is deigned to be infinitely variable. This enables this center speaker to be adapted for mounting at any desired point - whether free-standing or close to a wall or corner - without restriction.

The result is, in every respect, a complete success. Once correctly set up, the La Belle centre produces the same spatially separated, taught, dynamic and accurate results as we are already accustomed to from the La Belle column speaker. It is perfectly and harmoniously integrated in the system as a whole, enables a firm volume level and yet produces such an utterly clean-sounding surround system that the limits are defined only by the quality of the source and the ears of those listening. Both the quiet passages and louder sections are reproduced accurately and with attention to detail. No audible weaknesses are detectable and compression distortion is a term that is simply not used in connection with this speaker. The sum of these characteristics qualifies the La Belle Centre as a realistic alternative to the column speakers. This remarkable speaker, designed for everyday enjoyment but by no means mundane, is ideally suited as a powerful rear speaker. To ensure you make full use of the speaker’s capabilities (especially in the bass department), it is recommended that you do not use a high-pass filter in conjunction with your surround amplifier.

MONITOR 890 MK III



monitor890mk3

It is well-known that there are two types of loudspeakers: hi-fi speakers that produce the most accurate, unaltered sound possible, and disco or musician's speakers, where the top volume level is of the utmost importance. These volume levels are normally only possible with horns but these often cause coloration of the sound. The MONITOR 890 MK III was designed specifically to combine the best of both worlds. In the mid-range, we use a driver & horn unit which is so dynamic and produces such undistorted music, that many a horn-disparager has had to admit that this is simply unbelievably "different". Two excellent quality woofers, TIW 300 - 8 Ohm, mounted in the 180 litre vented cabinet, generate a bass sound pressure that is physically tangible, as you have experienced with concert speakers. Combined with the first-rate TL 16 H - 8 Ohm high-range horn, we have created a loudspeaker system that breaks down the previously unbridgeable barrier between the hi-fi and the professional speaker.

The output levels of the mid-range driver and tweeter can be adjusted to the requirements of the locale using output controls. We recommend, initially at least, the following level settings: tweeter: -4 dB; mid-range: -4 dB. These can, of course, be adapted to suit the specific acoustics in the room and personal preferences.

Thanks to the added impedance linearising unit in the crossover unit, the Monitor 890 MK III is now even better suited to use with critical amplifiers (e.g. tube amplifiers).

NoBox 170



nobox170_1

Electrostatic tweeters have maintained unbroken popularity for several decades. The large but light diaphragm, which radiates sound to both sides of the diaphragm, generates light, overall unfussy sound with excellent spatial qualities that is not attributable to a particular source and fills the room evenly with music. This type of speaker is generally extremely complex to manufacture and, as a result, not easily affordable. However, it is possible to create a sound experience very similar to this using conventional cone speakers mounted in an open baffle.

For the NoBox 170, four high-grade WS 17 E - 4 Ohm bass drivers with paper diaphragms were selected that are optimised for free-air use. Due to the fact that they have no cabinet, they produce wonderfully clean low-frequency bass. Also, thanks to the dipole principle, they generate fewer standing waves, which means the bass tends to fade more quickly, so it can never become fuzzy and does not drone. On top of this, there is the WS 13 E - 8 Ohm mid-range driver that also features a paper diaphragm and a high quality standard, making it ideal for free air use. In order to maintain the same standard of visual appearance, acoustic quality (and to stay in a moderate price range) paper diaphragms have also been used for the tweeters. The TW 6 NG - 8 Ohm provides a fitting finish with finely detailed, clearly defined high-range frequencies to ensure the sound produced by the NoBox 170 is a harmonious whole. Since the tweeter is the only driver that is closed at the rear, a second driver is mounted back-to-back to emulate the dipole principle right through to the higher range. The level can be regulated and even switched off via a potentiometer. In this way, the tonal balance and the depth of the stage can easily be adapted to suit the actual listening environment and personal preferences. It is important to place the NoBox 170 at a sufficient distance from the rear wall to allow the considerable low-frequency bass to develop and so as not to restrict the depth of the stage layout.

Once correctly positioned and set up, the sound experience is fascinating: the NoBox 170 reproduces voices and instruments in the centre of the room with an airy lightness without artificially inflating them or shifting them laterally or in terms of depth. When seated in the middle of the listening space, the listener is treated to excellent clarity, but even in the seats right at the fringes of the space, the overall sound quality does not break up but remains faithful to its position and lively character in the room. Listening pleasure with the NoBox 170 is unusually stressless, the tonal balance and large-format diaphragm ensure superior performance down into the deepest bass regions of a standard one would not expect from such a small-sized speaker.

Anyone looking for a speaker arrangement with plenty of diaphragm area that can import a special atmosphere into the sitting room as a full-range dipole, close to the results produced by large electrostatic speakers, should look at - and listen to - the NoBox 170 very closely.

PENTATON BB



pentatonbb

Full-range loudspeakers are enjoying another comeback and arousing increased interest, embodying, as they do, everything that a point sound source should be. Large full-range loudspeakers like the B 200 - 6 Ohm have the additional characteristic of transmitting the sound in a tightly bundled beam, which produces a very tangible, three-dimensional effect and allows individual instruments to be easily located. A drawback of the system, however, is that this beaming process and the sensitivity are reduced at lower frequencies. The PENTATON BB was developed specifically as a cabinet based on the legendary B 200 - 6 Ohm but designed to compensate for these two disadvantages.

In a similar way to the QUADRO, additional full-range drivers are switched in to supplement the central driver, which is connected direct to the amplifier without an intervening filter, as the frequencies go down the scale. This allows the B 200 - 6 Ohm to develop its full potential with none of the impairments caused by frequency-dependent signal-carrying components, while the BG 20 - 8 Ohms, that are optimised for low-frequency response, maintain the extremely high sensitivity and beaming effect right down to the bass range. The additional full-range drivers are arranged symmetrically in two groups around the main speaker, which again creates an acoustic focus in the centre of the speaker cabinet. On top of this, the baffles in enclosures 2 and 4 and in enclosures 1 and 5 are angled inwards by 6° and 12° respectively. This feature guarantees that, assuming a typical listening distance of approx. 3 m, each of the drivers is exactly the same distance away from the ear and at the same angle. Given the size of these speaker cabinets, this is the only way to ensure that the phases of all the drivers are in sync across the entire frequency range.

The result of all these characteristics taken together is a sound image of the stage that could hardly be clearer or more precise. Even baritone male voices and large instruments such as the double bass or bassoon appear to be present full-size, in the right place on the virtual stage and in tangible 3D. Thanks to the enormous diaphragm area and the low moving mass, the PENTATON BB transforms dynamic jumps in the recording decisively and seamlessly into sound pressure and, with its superior handling, encourages the listener to increase the volume level until it is physically felt and yet it never becomes obtrusive or laboured.

And yet, this is definitely a speaker for connoisseurs of lower volumes. Even at low output levels, the overall sound quality is tangible and mature so that every tiny musical detail, however small, is projected audibly without the slightest distortion. The frequency response is remarkably linear for a loudspeaker of this kind, which is why the PENTATON BB is ideal for the authentic reproduction of every genre of music without restriction and will allow the listener to rediscover even old favourites thanks to its analytical and highly detailed approach.

Thanks to its high sensitivity and uniform impedance curve, the PENTATON BB is predestined for use in connection with high-grade tube amplifiers with relatively low output wattages.

QUINTETT



quintett

With a cabinet volume of just over 56 litres, the QUINTETT could not be said to be a small speaker. Despite its size, it comes across as elegant and sophisticated, thanks to the arrangement of its drivers and the slim baffle. Fitted with no less than five AL 130 - 8 Ohm, it is generously equipped but stopping short of exaggeration.

Four of the AL 130 - 8 Ohm, with a combined diaphragm area of 316 cm², are fitted in the bass reflex cabinet and generate sufficient bass, so no subwoofer is needed. The QUINTETT is based on a development idea suggested by the German "Klang & Ton" Hi-Fi magazine which was then finalised by modifying the crossover.

The uppermost of the five AL 130 - 8 Ohm, which is neatly housed in its own enclosed 5-litre cabinet, together with the tried-and-tested KE 25 SC - 8 Ohm ceramic dome tweeter, produce clear mid-to-high-range sound above 500 Hz.

In terms of its sound quality, the QUINTETT can be described as rich in detail and very precise. It uncompromisingly shows up every defect in a recording but, on the other hand, reproduces good recordings perfectly, without the slightest distortion and with remarkable positioning accuracy. Bass sound is reproduced very accurately and clearly and, thanks to the be-wiring connections, can be controlled separately from the mid- and high range frequencies. The QUINTETT is, as a result, not a speaker that produces some softened-down mash, it is, on the contrary, a realist that can easily cope with maximum volume settings.

QUINTETT LIGHT



quintett_light

Just as the light versions of VOX and COUPLET, the QUINTETT LIGHT is aimed at coming as close as possible to the outstanding sound quality of its "big sister", with substantial lower priced driver units.

When listening to both the QUINTETT and the QUINTETT LIGHT, the direct comparison attests: Goal reached.

The QUINTETT LIGHT is, as well as the QUINTETT, a high efficiency speaker with a very balanced frequency response. Only in terms of dynamics and maximum sound pressure level, the QUINTETT LIGHT cannot fully keep up with the outstanding performance of the QUINTETT.

Anybody who is into the concept of the QUINTETT, but at a more favourable price, is well advised to take a closer look at the QUINTETT LIGHT.

STARLET



STARLET

The STARLET is a 3-way speaker which is extremely good value for money. The individual drivers used here have all proved their worth in numerous well-known constructions.

At the bottom end of the frequency range, there is the W 200 S - 8 Ohm from the EXPERIENCE V 20, mounted in a 58 litre vented cabinet. The mid- to high-range is covered by the W 100 S - 8 Ohm and DT 94 - 8 Ohm from the ALTO series of speakers.

The impression given by the STARLET is of a solid low-frequency foundation with powerful, crisp bass. The mid-range has a pleasant, unobtrusive sound, and at the higher frequency ranges the STARLET produces sparkling, clear-cut treble. In a nutshell, the STARLET is an extremely reasonably priced column speaker with a well-rounded tonal character and good power handling capabilities.

SYMPHONIE



symphonie

SYMPHONIE's sound profile can best be described as very mellow and melodious. The two AL 170 - 8 Ohm 17-cm woofers generate a full-bodied but well-defined bass in their isolated bass reflex compartments that one would not normally expect of a design such as this. Even at the lowest bass frequencies, SYMPHONIE retains its fidelity and produces clear, precise sound even at high volumes.

The highlight of the SYMPHONIE system is the 50-mm G 50 FFL - 8 Ohm mid-range dome. In the mid-range, it is this driver that ensures unbelievably tangible reproduction of the stage arrangement and provides clearer detection of the central (vocalist's) position than that provided by many other systems. Even recordings that are not perfectly spatial come across as well separated from the speakers, thanks to the SYMPHONIE. As a result, longer listening sessions become a source of relaxed long-term pleasure.

In the high-frequency range, the well-known ceramic dome driver, the KE 25 SC - 8 Ohm, is used to good effect and rounds off the overall sound picture with its silky-smooth sound properties and outstanding linearity.

VIB 170 BP



vib170bp

When developing the VIB 170 BP, the main objective was to create a fairly compact column speaker with an extremely deep bass output, which is capable of reproducing the deepest regions of the audible frequency spectrum. A common bassreflex housing can reach this aim only partly. Therefore, a very rare type of cabinet has been realized, at least when looking at fullrange-loudspeakers: A double-sided ventilated bandpass. In this layout, a woofer which is mounted on an inner separation wall, is operating on two bassreflex-tuned volumes, a larger one and a smaller one. By means of a subtle tuning of the two cavities, a linear frequency response down to 35 Hz (-3 dB) could be obtained with a housing of only 75 liters. Not until then, the sound pressure level starts to drop rather quickly. The lower cut-off frequency (-10 dB) is located around 24 Hz. Some very large bassreflex speakers are capable of reaching similar cut-off frequencies, but the SPL already starts dropping at much higher frequencies. This is why those kinds of loudspeakers sound less voluminous and deep.
Due to the exceptionally high excursion limit of the TIW 200 XS - 8 Ohm, the maximum obtainable sound pressure level is already physically tangible and more than sufficient even for large listening rooms.

Another design feature of the VIB 170 BP is the wide frequency range of the AL 170 - 8 Ohm. By means of a sophisticated crossover set-up, we have been successful in taking advantage of the outstanding acoustical properties of the AL 170 - 8 Ohm from 100 Hz up to 8 kHz. Not until then, the established ceramic tweeter KE 25 SC - 8 Ohm takes over to render the uppermost 1-2 octaves. By this layout, the widest part of the audible spectrum is reproduced by only one driver, which helps acoustical imaging and leads to a strikingly precise stage arrangement.

So how does such a fancy build sound like? Like the best of both worlds: The spatial precision and dynamic of a good fullrange driver, paired with the brute bass power of the TIW 200 XS - 8 Ohm in the bandpass cabinet and the silky, delicate treble of the excellent ceramic calotte.
At the same time, the whole loudspeaker plays all of a piece and acts absolutely neutral in terms of tonality. Moreover, not a hint of the often-cited "sponginess" of the bandpass principle could be observed, far from it: the low tones sound firm and massive, fully grown, thus becoming to many a much larger boxes.

All around, the VIB 170 BP can be said to be a felicitous loudspeaker, which combines the advantages of a high class fullrange speaker, a multiple way box and a strong subwoofer in one slim cabinet.

TIP: The low frequency part of the VIB 170 BP, without the tweeter and the midwoofer, and without the crossover network, makes a superb subwoofer to complement even large home cinema systems, single- or pairwise.

VOX 200



VOX200

The VOX 253 is well-known as a speaker system with unusual credentials. Although relatively slim, some people may wish for a less noticeable speaker cabinet. Building a smaller cabinet and maintaining the same characteristics is a tall order. The precondition is that if the dimensions are reduced, the main features should be retained. This means locating the woofer in the side wall, d Appolito arrangement for the two cone drivers with metal diaphragms and dome tweeters in the middle. The excellent AL 200 - 8 Ohm serves as a bass speaker and the tweeter is the G 20 SC - 8 Ohm , already very successfully used in the COUPLET model. It was, then, necessary to develop a completely new 10 cm high-end cone driver with a metal diaphragm. Although the development time was relatively long, the wait was worth it - this is a really first-class low- to mid-range unit with a cone made of pure titanium, equally as good as the AL 130 - 8 Ohm. The cabinet dimensions have been proportionally reduced from the large-scale VOX model to produce an almost dainty compact column speaker: the VOX 200.

The take-over frequency levels of 200 Hz and 3000 Hz have been retained. A crucial feature is that the large-sized bass reflex tunnel is also present. In this manner, we have managed to create a compact baby sister for the VOX 253 that is worthy of the family name. As one would expect, the VOX 200 cannot keep up with the 253 when it comes to really tough bass activity, where the 253 would master it with ease. In normal sized rooms this is hardly necessary or required. In any case, the bass capabilities of this smaller sister are far beyond what you would expect from a model of this size.

In the mid- to high-frequency range, smaller speakers are preferable anyway. This is also the case with the VOX 200. The sound breaks away clearly from the baffle and generates a stable volume level and uniform sound throughout the room with no colouration.

Once again, the G 20 SC - 8 Ohm proves its value as a producer of wonderfully clear, lively high-frequency reproduction without the slightest hint of aggression.

If you find large speaker cabinets too much of a good thing, you really ought to have a listen to the VOX 200!

VOX 200 LIGHT



vox200light

Soon after its launch, the VOX 200 became one of the most popular and successful high-end kits. Several excellent tests in numerous specialist magazines have demonstrated that this system is at a quality level normally expected of far more expensive candidates. We were asked whether it was possible to fit these cabinets with much cheaper loudspeakers and still get good results.

At the lower frequency end, we replaced the AL 200 - 8 OHM with the W 200 S - 8 OHM and also took out the TI 100 - 8 OHM mid-range loudspeaker, replacing it with two W 100 S - 8 OHM. We left the G 20 SC - 8 OHM dome tweeter unchanged. Initial tests showed that only a slight adjustment to the crossover were required. In terms of sound quality, the modified VOX put up an excellent showing in comparisons with the original.

VOX 253



vox253

The VOX 253 is an upright speaker with its subwoofer TIW 250 XS - 8 Ohm let into the side-wall. This design enables the front panel to be kept very narrow making it that much easier to position. One of the most outstanding features of the TIW 250 XS - 8 Ohm is its unbelievable ability to reproduce the lowest range bass in surprisingly small cabinets. In the listening area, the bass pressure becomes tangible rather than audible, the sort of effect you would normally only expect from much larger speakers. As a result of the side-opening position of the TIW 250 XS - 8 Ohm, the separating frequency between the subwoofer and the mid-range drivers has to be very low. This has been achieved by means of an especially intelligent frequency cross-over design.

In order not to restrict the dynamics at higher bass levels, a bass reflex tube with an exceptionally large cross-section and corresponding length has been designed. In this way, flow-related losses are kept to a minimum. The vent is at the bottom in the rear wall so as not to interfere with the attractive appearance of the front face.

The only difference between VOX 253 and VOX 252 is the new woofer TIW 250 XS - 8 Ohm. A change of the crossover was not necessary.

This version of the VOX contains the high-end ceramic dome tweeter KE 25 SC - 8 Ohm. An 18 dB high-pass filter produces an optimum phase relationship between tweeter an midrange. This creates an improvement of the clear location of each individual voice or instrument.

VOX 253 MHT



vox253mht

Due to the deep starting frequency of the MHT 12 - 8 Ohm it is possible to make use of this magnetostat in the VOX 253. Of course, the crossover has to be changed from that used in the original version with its KE 25 SC - 8 Ohm. Fortunately, the AL 130 - 8 Ohm 's only have to be separated slightly higher which means we are still a long way from the baffle resonance levels. Here, too, the transfer frequency is 3000 Hz. As can be seen from the dotted frequency curves for the individual drivers, the AL 130 - 8 Ohm drop off at 2000 Hz and the MHT 12 - 8 Ohm at 4500 Hz and meet again at 3000 Hz and -6 dB. The magnetostat need not by any means produce its full output at 3000 Hz, as some people often believe. This would not make sense in terms of achieving the lowest possible distortion factor.

Since the front panel of the MHT 12 - 8 Ohm is slightly larger, the AL 130 - 8 Ohm 's have to be spaced a little further apart (10 mm).

As regards their sound quality, both versions (original VOX 253 with KE 25 SC - 8 Ohm and VOX 253 MHT) are at the same high level. The version preferred by each particular customer will depend on personal taste, the type of music you listen to and how you listen.

VOX 253 MTI



vox253mti

The VOX 253 MTI is the current highlight in the VOX series. The uncompromising approach, involving fitting the TI 100 - 8 Ohm as the low- to mid-range unit and the MHT 12 - 8 Ohm as the tweeter, worked highly successfully in the TOPAS. Following the basic design concept of the VOX series, this system is fitted with two TI 100 - 8 Ohm 's as low- to mid-range units and the TIW 250 XS - 8 Ohm as the woofer.

One particularly convenient innovation is used for the first time in the VOX 253 MTI: it is now possible to tune the bass output level on the crossover unit. Depending on the acoustic properties of the room and personal preference, the bass output might be too strong, if the speakers are placed close to a wall, for example. The adjustment unit is mounted on the crossover unit directly parallel to the woofer and enables to listener to adjust the output level between 70 Hz and 150 Hz. The lower-frequency bass is not affected. Increasing the resistance affects the bass output: 10 ohms for a minimal reduction in bass and 3.3 ohms for maximum reduction. If the adjuster is left open (i.e. resistance is infinite), bass output reduction is deactivated.

VOX 301



vox300

The VOX 301 extends the high-end VOX series upwards. While the mid-to-high-range is the same as in the VOX 253, the TIW 300 - 8 Ohm has been chosen as the woofer for this model. As a result, while the excellent characteristics experienced in the mid-to-high range remain the same, the level accuracy and dynamics in the bass department have been increased and the lower limiting frequency reduced to a remarkable 23 Hz. The VOX 301 can, therefore, be seen as the VOX variant for high-volume aficionados who like to hear concerts at close to the original sound levels in large rooms.

VOX 80



vox80

This the smallest member of the VOX family is an exactly scaled-down version of the larger models. The dimensions of the VOX 253 have been reduced by a factor of around 3. The driver concept, consisting of two mid-range loudspeakers and a side-mounted woofer, corresponds to the other VOX versions. The two 5 cm full-range FRWS 5 R - 8 Ohm speakers fit perfectly in the baffle and cover mid-range. The smaller CP 13 - 4 Ohm tweeter ensures that the higher-frequency, although already well covered by the FRWS 5 R - 8 Ohm, is further strengthened. The woofer in this set is an F 8 SC - 8 Ohm full-range loudspeaker.

In order to be worthy of the honour of being included in the VOX family, the VOX 80 is fitted with a crossover which is just as conscientiously matched to the drivers as those in the larger models.

The results can be both seen and heard. The VOX 80 is an eye-catcher as well as an ear-catcher on any desk as a PC-based hifi, for example.

The VOX 80 has a power handling of 20/30 watts. In practice, in a PC environment, however, this output level is seldom, if ever, required. Set to an output of one watt, one VOX 80 will generate approx. 80 dB in a workplace, both speakers together create 86 dB. This is very loud. A miniature amplifier like the Visaton AMP 2.2 or AMP 2.2 LN will, therefore, be perfectly sufficient for most applications.
