Bowers and Wilkins CCM-746-S Brochure

CCM 746S
The combination of convenience and performance that is a feature of the entire Custom Installation range is no better
demonstrated than by the CCM 746S ceiling speaker. It marries a woven Kevlar® coned twin voice-coil 165mm (6½ in)
bass/midrange driver with an offset array of two high performance 25mm (1 in) aluminium dome tweeters. Thanks to its highly
accurate and natural sound, Kevlar® features on our most advanced high performance hi-fi speakers and it brings the same
qualities to the CCM 746S. The twin voice coils and tweeters combine the stereo signal to enable the use of just one ceiling
speaker in an installation zone without the loss of one audio channel. The CCM 746S also includes three-way switchable high
frequency equalisation.
