Characteristics and sound properties

For those who feel that the ATLAS DSM MK III is just too high and too wide, the ATLAS COMPACT MK III could be just the thing. The aim here was to slim down the size of the cabinets without compromising the excellent sound characteristics of the ATLAS DSM MK III. If you want to cut down the volume of a speaker cabinet without losing too much of the lower bass range, you have to use a bass driver with a smaller diaphragm area. As far as the lower frequency extremes are concerned, the ratio of diaphragm surface area to cabinet volume is of the utmost importance. In this context, the TIW 360 8 Ohm is the ideal bass speaker and the AL 170 8 Ohm optimal as a low- to midrange unit. Of course, a 40 cm subwoofer will generate more bass power than a 30 cm driver simply because it has a larger diaphragm surface area. But the tremendous power generated by the TIW 360 8 Ohm with optimal bass reflex tuning, should easily provide sufficient bass volume for most applications. The use of the same medium and high-range cones as in the ATLAS DSM MK III ensures a close relationship in terms of sound quality with the larger model.

This, the fourth version of the ATLAS COMPACT, now boasts the latest driver highlights that the VISATON range has to offer. Apart from the TIW 360 8 OHM and AL 170 8 OHM used in the MK III version, the latest version makes use of the TI 100 8 OHM as the mid-range loudspeaker and KE 25 SC 8 OHM as the tweeter. The crossover unit has been completely redesigned and adapted to match the new drivers.

The baffle has also been changed. The wide bevels make the cabinet look that much slimmer and prevent edge-reflexions in the more susceptible mid- and high-ranges. The bass reflex tube has also been modified. By using a larger tube, flow noise and losses have been reduced.

The ATLAS COMPACT MK IV is a very dynamic speaker with powerful deep-black bass reproduction but without getting woolly in the bass department. Additional features are absolutely neutral voice reproduction and crystal-clear high-frequency sounds without sharp edges.

The ATLAS DSM MK III is a superlative column speaker - not only because of its impressive height of 1.70 m, but above all because of its acoustic qualities.
The 5-way combination employs the TIW 400 8 Ohm high-tech speakers as long-stroke woofers, TIW 250 8 Ohm 's as internal drivers, GF 200 2 x 4 Ohm 's as fibre-glass mid-bass units and the tried-and-tested DSM 50 FFL 8 Ohm and DSM 25 FFL 8 Ohm titanium cones as mid- to high-range unit.
After considerably improving the bass range in the MK II version compared with its predecessor by using the TIW 250 8 Ohm as the inner driver, the current model has been further refined as the ATLAS DSM MK III - by including the GF 200 2 x 4 Ohm as the mid-bass unit. The result is far improved pulse dynamics, leading to even more pleasurable listening especially at peak levels.
Let it be said to all owners of the ATLAS DSM MK II, that conversion to the MK III version is remarkable easy. The crossover unit of the MK II has been retained with no change. The GF 200 2 x 4 Ohm can be fitted straight into the cut-out in the baffle of the WS 21 BF and its rim will neatly cover up the existing screw holes.

For Dolby(r)surround and multimedia systems, where larger speakers are a requirement, the ideal choice is the CENTER 130 model. At the higher end of the range, the new magnetically screened 25 mm SC 10 N 8 Ohm textile dome units are used. At the higher end of the range, the new magnetically screened 25 mm SC 10 N 8 Ohm textile dome units are used. The SC 13 8 Ohm 's are arranged symmetrically around the tweeter and are separated using two low-pass filters with differing characteristics in order to avoid wave cancellation affects around the tweeter. In this way, the sound source is always positioned around the centre and will match the on-screen visual action.
Thanks to the excellent power handling capabilities and the linear frequency response of the CENTER 130, home video presentations become a cinematic event. In multimedia applications, two CENTER 130 's are used to reproduce the computer sounds, which really bring out the best in your soundcard.

The CONCORDE MK II 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 crossaver 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 II version, a slight adjustment in the mid-range section of the crossover has enhanced the crossover range between the mid-range and tweeter.

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

Characteristics and sound properties

Subwoofer satellite arrangements are becoming ever more popular amongst those who simply do not have room to place large-scale speakers or who are unwilling to have large items of furniture around, but who do not wish to go without the enjoyment of powerful, low-range bass. Since low-frequency sounds below 100-150 Hz cannot be located by the human ear, only one subwoofer cabinet is required. The difficulty here is the combination of left- and right-channel low-range frequencies into a single loudspeaker. An uncompromising solution to this is an active crossover unit, which has a corresponding effect on costs. Special loudspeakers with completely separate voice coils make a simple construction of the subwoofer crossover unit possible. If you are intending to use normal bass speakers, a smart trick will solve this problem and kill two birds with one stone: the compound principle. With this arrangement, two bass speakers are screwed together in such a way that they are acoustically coupled via a small air volume. This produces a loudspeaker with two separate voice coils. Despite the relatively small volume in the chamber, very low frequency extremes are achieved. When connecting up the woofers, remember to transpose the polarity on one of them as otherwise the two speakers will be working against each other. In order to ensure the satellite speakers are perfectly matched to the subwoofers, they are vented, too. This enables the volume to be raised at lower frequency ranges. At around 3,000 Hz the ferrofluid-filled textile DTW 95 NG 8 Ohm takes over. A characteristic of this dome tweeter is the "smooth" high-range treatment. If more brilliant high-range frequency output is required, the DSM 25 FFL 8 Ohm with its metal cone can be substituted without altering the crossover unit.

Characteristics and sound properties

This compact centre speaker will find a suitable space in the shelving just above or below the TV set. It is fitted with two W 100 SC 4 Ohm 's connected in series, which produces a total impedance of 8 ohms. As a result, the CT CENTER 100 can be used in conjunction with receivers that have problem communicating with low-impedance speakers. Up in the high-frequency range, the G 25 ND 8 Ohm, a 25 mm textile dome unit with a Neodym magnet, performs well. The tweeter is arranged asymmetrically between the woofers in order to achieve an enhanced horizontal radiation pattern. All the drivers are, of course, magnetically shielded to prevent annoying interference effects on TV screens.
Apart from the CineTOP 100 combination consisting of 2x CT MAIN 100, 1x CT CENTER 100, 2x CT DIPOL 100 and the active subwoofer, it is also possible to combine the Centre and Dipole speakers with small or medium-sized upright speakers such as the ALTO II, ALTO III C or ALTO LINE. As subwoofer, the SUB W-20.39 would be a suitable choice.

Characteristics and sound properties

The CT CENTER 130 has been specially developed with a particular driver arrangement in mind to provide perfect omnidirectional sound dispersion and to ensure the sound source is close to the image. Spoken dialogues can thus be directly located and correctly positioned even 30° from the centre line without distortion. The W 130 SC 4 Ohm loudspeaker model and the 25 mm SC 4 ND 4 Ohm titanium tweeter with its neodym magnet are magnetically shielded. The sealed 2-way speaker, with only 8 litres net cabinet volume, has a Q-rating of 0.7 and a linear frequency response of 100 Hz to 20,000 Hz. If used, as recommended, at 100 Hz at above, it can easily manage maximum levels of 105 dB. During the development of the system, care was taken to ensure that the high rated impedance allows its use with virtually any amplifier. If the speaker is not supplied with an amplifier signal which is trimmed under 100 Hz, it is advisable to add the recommended passive high-pass filter, in order to prevent overloading at higher output levels in the lower bass frequency ranges. As an option, it is possible to combine the CT CENTER 130 with an additional SUB T-25 active subwoofer with a cut-off frequency of 100 Hz which produces a high-grade centre system, which covers the entire frequency range, has excellent power handling capabilities and still remains very compact, enabling it to be easily positioned. The CT CENTER 130 can be used in all CineTOP systems, such as the CineTOP 170 or 200 for normal sitting-room use. If placed upright, the CT CENTER 130 can also be used as a main loudspeaker for compact home video applications, where it would require the support of a subwoofer, e.g. SUB-T 25. The CT CENTER 130 is characterised by its excellent omnidirectional sound distribution and balanced sound qualities, that reproduce film soundtracks in all their colour and depth.

Characteristics and sound properties

CT CENTER 170 is based on the CT MAIN 170 main loudspeakers and acts as a Centre Speaker, where the only difference is that it is designed to lie on its side. Since the speaker arrangement and crossover unit are identical in every respect, this centre system is ideal for use with THX® systems. With its linear frequency response of 80 Hz 20,000 Hz in an enclosed cabinet with a total Q-rating of 0.7, the required vertical beaming and a maximum sound pressure of 108 dB, this system leaves nothing to be desired. The loudspeakers used, W 100 SC 4 Ohm and W 170 SC 4 Ohm, are magnetically shielded and the shielding of the complete speaker unit corresponds to THX® regulations (3-Gaussian curve). This means that the entire speaker can also serve as a stand for a TV set. The speaker is a titanium dome tweeter with a neodym magnet. The CT CENTER 170 can also be used as a main loudspeaker and, because of its overall dimensions, can be placed on top of a SUB T-36 subwoofer which is lying on its side.This speaker has extremely clear bass reproduction with a well-balanced overall sound quality, providing a realistic impression of live sound. Even high volume settings come across naturally and undistorted. The designers placed emphasis on hig impedance, so that the speakers can be connected up to virtually any amplifier with no problems. We recommend using this system in conjunction with CT MAIN 170 main loudspeakers, the CT DIPOL 130 effect speaker and the SUB T-36 subwoofer. The realistic sound reproduction especially for films is so close to the original that the listener feels as if they are right in the thick of it. This system is a joy to listen to.

The CT CENTER 200 can also be used as a main loudspeaker and, because of its overall dimensions, can be placed on top of a SUB T-40 subwoofer. This speaker has extremely clear bass reproduction with a well-balanced overall sound quality, and impressive spatial separation. High volume settings, particularly important to reproduce live sound, come across powerfully, naturally and undistorted involving the listener directly in the action. The designers placed emphasis on high impedance, so that the speakers can be connected up to virtually any amplifier with no problems. We recommend using this system in conjunction with CT MAIN 200 main loudspeakers, the CT DIPOL 130 effect speaker and the SUB T-40 subwoofer. The virtually perfect reproduction of the sound channels is so close to the original that the listener feels as if they are personally involved in the action. Makes films into an experience.

The CT CENTER 80 is a compact, enclosed 2-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 SC 8 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. This also provides for application in a subwoofer satellite system with the CT SUB 80. In terms of sound quality, the CT CENTER 80 produces clear-cut sound, well removed from the speakers, but with remarkably well-formed bass reproduction for a system of this size. In conjunction with the CT SUB 80 system and two CT EFFECT 80 's, the CT CENTER 80 provides an excellent surround sound "starter" system, that will transport viewers right into the centre of the action with centrally located dialogues, background noises and dramatic sound effects.

Characteristics and sound properties

This dipole speaker makes use of two W 100 S 4 Ohm and two G 25 ND 8 Ohm textile dome units. The idea of dipoles is to create a diffused sound field from the effect channels. For this reason the tweeters at the front and rear are cross-connected. The all-pass circuitry in the deep-bass department ensures that, at frequencies above 200 Hz, the woofers are also cross-connected, and below that level they work in synch. This prevents the bass completely cancelling itself out. The two dipoles should be positioned at both sides of the listening position and just above ear-height or mounted on the wall at that height.

Apart from the CineTOP 100 combination consisting of 2x CT MAIN 100, 1x CT CENTER 100, 2x CT DIPOL 100 and the active subwoofer, it is also possible to combine the Centre and Dipole speakers with small or medium-sized upright speakers such as the ALTO II, ALTO III C or ALTO LINE. As subwoofer, the SUB W-20.39 would be a suitable choice.

Characteristics and sound properties

For use as a small satellite, the CT MAIN 100 is equipped with a pair of W 100 S 4 Ohm and the G 25 ND 8 Ohm textile dome unit. The two woofers are connected in series, which produces a total impedance of 8 ohms. As a result, the CT MAIN 100 can be used in conjunction with receivers that have problem communicating with low-impedance speakers. The drivers are arranged symmetrically on the baffle based on the D'Appolito principle, where the oval front panel of the tweeter leaves only very little space between the woofers.
The CT MAIN 100 can be used as the main speaker in a multichannel system (e.g. CineTOP 100 combination using 2x CT MAIN 100, 1x CT CENTER 100 and 2x CT DIPOL 100, boosted with an active subwoofer), or as the satellite in a stereo system. As subwoofer, the SUB W-20.39 would be a suitable choice.

Characteristics and sound properties

The CT MAIN 170 speaker was originally developed as a main loudspeaker for home video applications but is equally well suited to listening to hi-fi music. This enclosed 3-way cabinet features a front baffle arrangement based on the D Appolito principle arranged symmetrically around the 25 mm titanium SC 4 ND 4 Ohm tweeter with neodym magnets. The loudspeakers used, W 100 SC 4 Ohm and W 170 SC 4 Ohm, are magnetically shielded. In order to suppress any unwanted interference by the 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 linear frequency response of the speaker is 80 Hz 20,000 Hz, which produces a total Q-rating of 0.7 in combination with the vertical beaming effect, and a total SPL of over 108 dB, corresponding to the THX® requirements. The CT MAIN 170 can equally well be used in small or large rooms. Mounted on a stand, the cabinet becomes an column speaker. The CT MAIN 170 produces precise bass reproduction and an exceptionally well balanced sound experience that is able to compete with live music. Even high volume settings will come over naturally and will not lead to distortion. The designers placed emphasis on high impedance, so that the speakers can be connected up to virtually any amplifier with no problems. We recommend using this system in conjunction with CT CENTER 130 or CT CENTER 170 centre speakers, the CT DIPOL 130 effect speaker and the SUB T-36 subwoofer.

In order to suppress any unwanted interference by the 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 linear frequency response of the speaker is 80 Hz -20,000 Hz, which produces a total Q-rating of 0.7 in combination with the vertical beaming effect, and a total SPL of over 110 dB, corresponding to the THX® requirements. The CT MAIN 200 can equally well be used in small or large function rooms. Mounted on a stand, the cabinet becomes an column speaker. The CT MAIN 200 provides precise bass reproduction and exceptionally good sound quality and spatial separation. Peak volume levels, so important for a realistic live sound experience, come over naturally and without the slightest distortion. The designers placed emphasis on high impedance, so that the speakers can be connected up to virtually any amplifier with no problems. We recommend using this system in conjunction with CT CENTER 130 or CT CENTER 200 centre speakers, the CT DIPOL 130 effect speaker and the SUB T-40 subwoofer.

Characteristics and sound properties

We are proud to present the CT CENTER 80, specially designed for Dolby®-Surround applications. This is a highly compact system for the home video centre channel (240 x 105 x 200 mm; fitted with 2 x SC 8 8 Ohm, 1 x SC 5 8 Ohm ). This loudspeaker has well-balanced sound qualities. For this reason, we recommend using two CT CENTER 80 's as satellite speakers in conjunction with a specially designed subwoofer as main loudspeakers. The CT CENTER 80 speaker is then used three times: as the centre speaker and as a main loudspeaker with a subwoofer booster. This sub/sat system is also well suited to compact hi-fi stereo systems. For the subwoofer, the bandpass principle has been chosen, since it is only this arrangement with a passive crossover unit that the low cut-off frequency of 125 Hz can be achieved at the same time as a high slope rate. The system uses two magnetically shielded W 130 SC 4 Ohm loudspeakers, each supplied by one channel (R+L). The high pass for hooking up the satellite speakers is also integrated in the crossover unit. The frequency curve shows that we have managed to raise the slope rate to such a level that the subwoofer cannot be located. Furthermore, the satellite speakers are freed of their subwoofer content, which means they come across extremely clearly even at high output levels. Thanks to its compact dimensions, the CT SUB 80 system can be placed discretely anywhere in the room and the magnetically shielded subwoofer can even be used as a base for a TV set. The frequency curve also shows that the system has remarkably good efficiency for its size - and retains a voluminous, even warm sound character. The spatial reproduction is extremely good - a characteristic of smaller satellite speakers. The CT SUB 80 system when combined with the CT CENTER 80 and two CT EFFECT 80 's will provide an excellent surround starter set, that will present the listener with centrally placed dialogues, background noises and dramatic sound effects that all in all will put you right at the heart of the action.

Characteristics and sound properties

Connoisseurs of crisp, powerful bass and clear higher range frequencies, coupled with excellent power-handling capabilities, will welcome the 65-litre FIESTA 20 speaker, because it was designed specifically for them.
A special crossover circuit enables the two W 200 NG 8 Ohm to work in the bass range in tandem up to around 120 Hz. After that, the output level of the lower speaker is lowered and the upper W 200 NG 8 Ohm takes over the mid-range. The pressure chamber system of the DHT 9 8 Ohm produces high-range dynamics with amazing signal fidelity and is effectively protected against overloading by the voltage attenuator connected in series.
The special sound characteristics of this system will appeal mainly to rock music fans. This musical genre often requires high output levels and needs the right punch in the bass range. It is precisely these features, good power handling capabilities and authentic bass reproduction coupled with a moderate price that make the VISATON FIESTA 20 what it is.

Characteristics and sound properties

A loudspeaker that produces similar sound characteristics in the hi-fi field as the FIESTA 20, but, due to its higher efficiency rating, can also double up as a speaker for the electronic organ at home and be used in the party room; that is the FIESTA 30.
At the lower end of the frequency scales in this all-round system, we find the tough 12" BG 30 NG 8 Ohm in a generously sized 130-litre vented cabinet. The mid- to high-range is covered by the new BG 20 8 Ohm and the DHT 9 8 Ohm tweeter horn.
The result is a high efficiency rating of 91 dB (1 W/1 m) at impedance levels that are not amplifier-sensitive and a music load of no less than 250 W.
The robust reproduction quality required for party use or for a musician is complemented adequately by the smooth frequency response with the neutral hi-fi sound qualities required in a home listening environment.

The FILOU is a D'Appolito configuration designed as a shelf-mounted speaker, but thanks to its excellent bass reproduction, can also be free-standing. It is based on the vented cabinet principle. The bass to mid-range is covered by two WS 13 BF 8 Ohm speakers. The extremely small moving mass coupled with the powerful driver and the rounded overall concept of this 13cm driver makes it possible to use it as a mid-range unit. At about 2,600 Hz, the two mid-bass units working in parallel are reduced and the DT 94 8 Ohm dome tweeter linked up. The FILOU is characterised mainly by its powerful and accurate bass reproduction and, due to the high efficiency level, lively, bubbly music reproduction. Its excellent sound distribution characteristics contribute to spatial clarity and good positioning with music. Thanks to the relatively high efficiency rating coupled with good power handling capabilities, louder volume levels can be easily achieved with no sound distortion. As long as the overall cabinet volume is retained, the unit can be built slightly wider and shorter (e.g. width: 230 mm, depth: 300 mm).

Characteristics and sound properties

For sound reproduction in large halls or in the open, you need loudspeakers with a high efficiency rating. This means that the electrical input has to be converted to sound output with the minimum possible loss. Since the mid- and high-range sound is dampened more than the bass sound as the distance from the loudspeaker increases, the frequency response of a speaker designed for this application has to rise as you move up the frequency scale. Otherwise, the speaker will sound dull at a distance.

The MB 212/H musician's P.A. system has the required characteristics and is therefore well suited to use in discos, as an outside small-volume P.A., or as a vocals and instrument speaker. The two powerful 30-cm musician's subwoofers run parallel up to around 4,000 Hz, at which point the robust, but neutral-sounding HTH 8.7 8 Ohm high-range flare takes over.

The following calculation shows how important it is to have the right efficiency rating for professional P.A. speakers: the MB 212/H speaker generates a mean sound pressure of 98 dB at 1 watt and at 1 metre from the speaker. At the maximum permanent load of 300 W, the maximum achievable at 1 metre is 123 dB. In the open, measured at 60 metres from the speaker, the level is merely 87 dB.

Suppose we were to use a normal hi-fi speaker with a high efficiency rating of 90 dB/1 W/1 m, it would take 1,900 watts (!) to achieve 87 dB at a distance of 60 metres. As you can see, no normal hi-fi speaker is in a position to achieve anything like the required compression-free sound output.

Characteristics and sound properties

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 II 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 360 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.
We recommend, initially at least, the following level settings: tweeter: -4 dB; mid-range: -4 dB
Thanks to the added impedance linearising unit in the crossover unit, the Monitor 890 MK II is now even better suited to use with critical amplifiers (e.g. tube amplifiers).

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.

The NANO SUB PR is a smaller alternative to the original NANO SUB. The capacity of the cabinet has been reduced to 20 l. In order to achieve the required low tuning frequency with such a small cabinet, the bass reflex tube will either have to be extremely long or have a very small cross-section. Both will lead to considerable airflow losses. So instead of using a bass reflex tube, we use a PR 250 radiator. This enables us to design a far more compact subwoofer and, at the same time, compromise as little low-frequency bass as possible.
The tuning frequency can be adjusted on the PR 250 by means of the additional mass. Without the additional mass, 36 Hz is possible and with the enclosed nut and bolt, 30 Hz. Of course, since every room has its own acoustic properties, you should select the option that provides the best actual listening pleasure.
Apart from being used in the passive NANO SUB/SAT system, the NANO SUB PR can, of course, also be used in an active system, e.g. in conjunction with a Thommessen Proteus SW 0.8 amplifier. In this case, the GF 200 2 x 4 Ohm voice coils are connected in series while the passive crossover and terminal connections are no longer needed.

Characteristics and sound properties

Well designed 2-way speakers with excellent mid-bass speakers and equally good tweeters can work wonders in terms of their spatial qualities and localisation. One of the reasons for this is certainly that the a large, absolutely critical frequency range (up to around 4,000 Hz) is covered by a single loudspeaker driver. In other words, there is only one sound source and no possibility of interference or loss from an intermediate crossover. In addition, the narrow baffles in such speakers tend to have a positive effect on omnidirectional sound distribution and the intended related characteristics.
The SKYLINE is indeed a 3-way combination, but, in contrast to usual practice, with a very low cut-off frequency between the low- and mid- to low ranges (here around 300 Hz). This keeps the cone still, but the system still manages to produce sufficient low-range bass. In a sense, the SKYLINE is nothing more than a 2-way speaker with a subwoofer.
The WS 13 BF 8 Ohm is one of the few mid-range cone drivers, that produces a completely linear frequency response across the entire transmission range up to 5 KHz. If the SKYLINE is placed in a room with at least moderately good acoustics, the exact positioning of the instruments or voices is immediately noticeable. Even if the listener is not in the ideal central listening position between the speakers, the SKYLINE retains its precise positioning characteristics.

The question we asked ourselves during the development of the SUB T-25 was, "Is it possible to design a subwoofer with a minimal cabinet volume of just 30 litres as low-range bass support for home video applications and even for medium-sized column speakers?"
The answer was a definite "yes". This was realised using a special 30 litre cabinet, the TIW 250 8 Ohm and an active subwoofer module (not included in delivery!). Inside the vented enclosure, the TIW 250 8 Ohm is mounted on the baffle, so that a front-opening port makes sense both optically and acoustically. The subwoofer is then magnetically shielded using an additional compensating magnet. The amplifier module is mounted to the rear of the subwoofer. In practice, a cut-off frequency of 50 Hz provides a lower frequency extreme of just 25 Hz. Low-range bass freaks can now add this extreme bass functionality to their existing speaker arrangement at a maximum sound pressure of 106 dB. For home video applications the cut-off frequency of 100 Hz is the right choice. With this arrangement, the ratio of low-range bass to efficiency shifts in favour of the maximum level, which is then 112 dB. The lower frequency limit still rises to a remarkable 40 Hz. If set up in the corners of the room, an additional 9 dB can be added to the rated maximum acoustic pressure. In this way, it is possible to achieve optimum bass output depending on your taste and the acoustics of the room up to the limits of the rated maximum volume. The SUB T-25 is well suited as a subwoofer for small home video applications like the CT SUB/SAT 80 or CineTOP 130. It can even be used in conjunction with the centre-speaker CT CENTER 130 and the CT DIPOL 130 to make a fullrange centre-speaker or effect speaker.

The SUB T-36 subwoofer was developed to complement home video and THX® systems with an active subwoofer output and can, if required, be equipped with an active subwoofer module. The driver used is the TIW 360 8 Ohm, to which a compensating magnet can be added to shield off unwanted magnetism. The 12" speaker used achieves low-range frequency extremes of 35 Hz in this relatively small 63-litre cabinet. From 50 Hz to 200 Hz, the subwoofer produces a perfectly linear frequency response and achieves the THX® requirements with its Butterworth characteristics and an attainable distortion-free sound pressure of over 105 dB at 50 Hz. Used in conjunction with an active filter, the system achieves the required cut-off frequency and filter characteristics with ease and, at the same time, produces maximum sound pressure, of no less than 113 dB with the SUB T-36. If set up in the corners of the room, an additional 9 dB can be added to the rated maximum. Thanks to the special cabinet construction, low-range bass comes across intact, clearly and yet powerfully, so that effects such as explosions are not only clearly heard, but provide the listener with a tangible realistic live feeling, too. The SUB T-36 subwoofer in conjunction with the CineTOP 170 system is recommended for medium sized to large rooms. Lying on its side it can also be used as a base for the CT CENTER 170.

The TIW 360 X 8 OHM is well suited as a subwoofer in home theatre systems or as part of a hi-fi application, due to its heavy-duty diaphragm and low resonance frequency. In this sample arrangement, it is used in an enclosed chamber with a net capacity of 39 litres.

The passive arrangement will produce powerful, low-range bass, such as would normally only be possible with other drivers in far larger cabinets. If you add an 820 µF-capacitor before the TIW 360 X 8 OHM, the output level below 50 Hz will be raised and above this level it will be lowered. This lowers the lower limiting frequency to a remarkable 28 Hz. As a matter of interest, at 1 watt it is virtually impossible to measure a difference between the normal, coarse (very cheap) electrolytic capacitors and the smooth, high-grade ones. Film capacitors are definitely not required. At higher output levels, however the coarse electrolytic capacitors could heat up. Which electrolytic capacitors you use is really not so much a matter of sound quality, but rather one of operating safety. The precise specifications are less important. It would be possible, for example, to install another 1x 470 µF and 1x 330 µF or 8x100 µF (in parallel) instead of a 1x 820 µF.

Things really hot up, however, if you decide to use amplified speakers with an active crossover. We used the Thommessen Proteus SW 2.5, which provides a large number of setting options. The signal level is equalized below the installation resonance frequency in such a way that you get a good bandpass curve (bass EQ +6 dB at 23 Hz, low pass 50 Hz). The lower limiting frequency will then be at a breathtaking 20 Hz. Of course, since every room has its own acoustic properties, you should select the option that provides the best actual listening pleasure.

Variants: 1) passive
2) passive with an 820 µF capacitor
3) active with a Proteus SW 2.5 (without capacitor)

The SUB T-40 subwoofer is a completely uncompromisingly good vented system for use in an active installation and complements the bass range of multi-channel systems. The cube-like cabinet with an outer edge of 63 cm and sophisticated inner reinforcements has a total volume of no less than 200 litres!!! The short sides and damping of the cabinet combine to eliminate standing waves within the scope of application of the speaker. If required, the T-40 can also be supplemented with an active subwoofer module. The driver used is the TIW 400 8 Ohm, for which a compensating magnet is available to shield off unwanted magnetic interference. The 15" speakers mounted in this special cabinet construction with its extremely large bass tunnel enable the lowest frequency bass to be reproduced without any distortion and attains unbelievably low frequency extremes of 25 Hz. Between 30 Hz and 200 Hz, this subwoofer produces a perfectly linear frequency response, which, in conjunction with the Butterworth characteristics attained and a realistically distortion-free sound pressure of over 105 dB at 30 Hz, fulfils the THX® requirements. Combined with an active filter, the required cut-off frequency and filter characteristics can be exactly pre-set. The maximum sound pressure of the SUB T-40 is 114 dB. If set up in the corners of the room, an additional 9 dB can be added to the rated maximum.

The SUB T-40 will enable you to reproduce the lowest bass frequencies at high output levels and with no loss. The extreme cabinet stiffeners guarantee reduced resonance operation with clear-cut, powerful bass that you not only hear but feel as well. This subwoofer is the perfect choice if you want to feel the acoustic effects realistically - as if you were there!

The TL-SUB subwoofer is a special system for reproducing lowest-range bass frequencies accurately at subsonic levels. There are software effects around that produce frequencies of 20 Hz and even less. You just have to think of the almost proverbial sound effects of the Tyrannosaurus Rex in Stephen Spielberg's Jurassic Park.

If you are prepared and able to give up about half a cubic metre of sitting-room space and are even thinking of rearranging the furniture, the TL-SUB with its ultra-low bass is just what you are looking for. One thing has to be said right from the start: the bass churned out by this system at the lowest octave level is by no means the thumping disco bass that hits you right in the stomach, but is, on the contrary, as smooth as cream. It is not locatable in the room and is felt as a sort of air movement that makes your trouser legs move. The ultra-low bass give you a fascinating feeling of being there live - provided, of course, the software has the channel programmed into it.

As regards the speaker construction, we have a new double transmission line equipped with a TIW 360 8 Ohm and a TIW 400 8 Ohm. If required, compensating magnets are available for these drivers to shield them magnetically. By not damping the cabinets, tremendous efficiency has been achieved, which, if the speakers are positioned in the corners, will attain levels of 114 dB at 20 Hz and a maximum sound pressure of 121 dB from 30 Hz. The output level is restricted by the mechanical construction of the speakers, to prevent the mechanical load from exceeding 200 W. We recommend combining the system with an active subwoofer module with a cut-off frequency of 50 Hz and, preferably with a subsonic filter in the pre-amp to protect the loudspeakers against mechanical overloading below 15 Hz.

This definitive lowest-range subwoofer is also suitable for supplementing larger home video applications such as CineTOP 170 / 200 or VOX for large rooms and small cinemas. The subwoofer can equally well be positioned upright in a corner of the room or lying in front of a wall of the room. It might be said that the reproduction of that last octave of bass sound is something of a luxury, considering the expense, but real music and home video aficionados will welcome the uncompromising approach of this system. The TL-SUB generates "deep black" bass that will set the house rocking on its foundations and turns films that use this technology into unforgettable experiences.

The VIB EXTRA GF is a 3-way combination in a slim-line, column-like vented cabinet. The design of this cabinet means that a large cabinet volume (90 litres net) is achieved with relatively little loss of floor space. The woofer is mounted at the top in order to avoid annoying reflections from the floor and sympathetic resonance from the room. The narrow baffle and the asymmetric arrangement of the speaker drivers to one side generate excellent omnidirectional distribution characteristics. The result is good spatial sound output that is to a large extent independent of the listener's seating position. The crossover unit, designed especially for this choice of drivers and this cabinet, separates off the GF 250 2 x 4 Ohm fibre glass woofer at 800 Hz. The titanium mid-range dome speaker is active up to 6 KHz. From here, the DSM 25 FFL 8 Ohm tweeter takes over. The first thing you will notice about the sound produced by the VIB EXTRA GF is the remarkable band-width coverage. The lowest frequencies (20 - 30 Hz) that are not perceived as sound at all but as pressure on the body and ears come across just as readily through the VIB EXTRA GF. This bass reproduction is clear-cut and with good signal fidelity, but makes a smooth impression on the listener, not the gritty sort of bass you would get from musician's PA systems.
In "normal" sized rooms, an incredibly high level of bass is produced in the low frequency range, but
