Magnetically shielded 25 mm (1") fabric dome driver for the highrange above 3000 Hz. Linear frequency re-sponse due to special dome coating and ferrofluid-cooled voice-coil for high power handling. Suitable for shielded medium sized 2-way combinations for surround center speakers and multi-media systems in conjunction with the shielded low-midrange driver SC 13 8 Ohm.

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 Ohmtextile 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 CLOU is a slim-line 2-band column speaker offering real value-for-money as a key feature, as shown in the choice of two WS 17 E - 8 Ohmfor the low-to-medium frequencies and the SC 10 N - 8 Ohm for the higher frequency range. To guarantee balanced overall sound quality using these less-expensive drivers, the two mid-bass units are physically separated from each other and each has its own enclosure. The lower WS 17 E - 8 Ohm is mounted in a 36-litre compartment. This produces a uniform increase in the frequency response from 60 Hz up to 600 Hz. The upper WS 17 E - 8 Ohm, on the other hand, is mounted in a smaller 16-litre compartment, which causes a slight increase in the range of frequencies between 60 Hz and 150 Hz. However, taken jointly, the two mid-bass units create a harmonious bass foundation which deliberately emphasises the frequencies between 60 Hz and 130 Hz. To ensure a seamless transition between the tweeter and the bass drivers, you need a properly balanced damping circuit to cut out any unwanted peaks and resonance.
The result of this unusual combination of drivers and cabinet is a column speaker that has to be seen and heard to be believed and one which produces a sound quality well above its moderate price range.
