The ARIA DIPOL 1 is intended specifically as an effect speaker for the rear channels in multichannel systems. It unites two concepts: It can be used in both dipole and direct modes. By activating the two outer tweeters, something approaching the dipole effect is achieved, i.e. a diffused sound field. At the same time, the centre tweeter is deactivated. This solution cannot achieve the perfect diffused field of a full dipole set-up, which uses twin cones in the bass department as well, but it does represent a good, value-for-money compromise.
ARIA DIPOL 1 speakers can be combined wither with the other members of the ARIA family or with larger speakers such as the VOX 200.
The BIJOU 170 is a compact shelf-top speaker with high-end drivers as the original BIJOU. The AL 170 - 8 Ohm woofer in the closed 10.5 l case provides for a kick and exact bass which works well and without booming by mounting on a wall. This was reached by a slightly rising frequency response to about 1000 Hz, so that the BIJOU 170 should be used preferentially as a wall or shelf-mounted speaker.
In this duet the high tone reproduction takes over the also well known ceramic tweeter KE 25 SC - 8 Ohm which is extremely rich in detail and exact in work.
The BIJOU 170 is available as single version and can be used therefore e.g. as a centre speaker, but, of course, also as a front and effect loudspeaker in home cinema systems, supported by an additional subwoofer.
If you do not have much space for your surround speakers to the rear and sides of your cosy chairs, this smaller surround system, CT EFFECT 80, is the ideal solution. The cabinets are so small, they can be hidden anywhere. The FRS 8 - 8 Ohm fullrange speaker, with its extremely linear frequency response, is well-suited thanks to its frequency response of 100 Hz - 7.000 Hz.
Comprehensive practical tests have demonstrated that, as far as surround speakers are concerned, omnidirectional sound distribution is particularly effective. This system produces a spatial listening effect which is independent of the actual seat position. In order to achieve this ideal sound distribution, the FRS 8 - 8 Ohm is mounted in such a way that it points upwards. The bundling effect does not begin until very high frequencies are reached, as a result of the small size. The required 7,000 Hz are therefore easily distributed horizontally. The optimal position for these small speakers is at head height beside the wall or in a corner of the room, behind the seats and to the sides. The relatively low power handling capabilities of these small speakers is of secondary importance because with this fullrange surround system the high-output, low frequencies are not included in the effects channel of the Dolby®-Surround Prologic system. Furthermore, a sound system is considered to be ideally set up if the sounds are felt to be coming from in front of the listener. These effect speakers generate a quieter, more diffused impression of the sound, which is not intended to be easily located. In terms of their sound output, these easy-to-make speakers will satisfy your spatial expectations. All the sounds encoded in films using the Dolby®-Surround Prologic system to include spatial effects are reproduced naturally and at more than sufficient volume levels for normal sitting rooms.
In conjunction with the CT SUB 80 system and the CT CENTER 80, two CT EFFECT 80 's provide 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.

The 2-way FONTANA system is a 360° omnidirectional speaker with a highly attractive appearance and is particularly well suited as an effect speaker. The speakers are arranged so that they point upwards and reflect the sound output by means of two specially shaped cones. This results in a uniformly distributed frequency response, that matches your hearing expectations in the room.
The best sound quality is achieved if these omnidirectional speakers are positioned about 50 cm to 1 m from a wall. This produces spatial sound of such tangible quality that it is perceived at any position in the room. Virtual sound sources, such as instruments or voices perceived to be between the speakers, can be clearly located from any seating position in the room, which gives listeners a freedom of movement in the room they have never had before and this holds true even in acoustically difficult rooms. This results in extraordinary diffusion fields for the effects channels in Dolby® Surround and multi-channel systems.
The DT 94 - 8 Ohm tweeters, ideal for this type of system, working in conjunction with the mid-bass AL 170 - 8 Ohm and the carefully tuned crossover unit, ensure balanced, neutral sound reproduction. Low-range bass frequencies are boosted by the BR 15.34 tube, which is situated in the bottom of the bass chamber and guarantees clear, powerful bass reproduction.
The omnidirectional FONTANA, tested in an anechoic chamber, achieved a maximum volume of 98 dB. If positioned, as recommended, near a wall, however, the system produces + 6 dB or, in a corner of the room, + 9 dB, making this omnidirectional speaker ideally suited even for larger rooms. If required, two FONTANA's can be installed on each side to produce a full surround field. To do so, position one omnidirectional speaker to the side of the seating arrangement and a second one behind that. The same applies to the other side.
The FONTANA is ideal as a fullrange effects speaker system for high-quality surround sound systems for movies and music, but can just as well be used as the main loudspeaker for hi-fi stereo systems to give you excellent spatial listening pleasure for your favourite music.
