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.
