Visaton CLOU / Hi-Fi speakers DIY

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.
