Bowers & Wilkins CCM663SR Two-Way 6" In-Ceiling Speaker - Manual

Custom Installation
CCM663SR
See nothing, hear everything
The combination of convenience and performance that is a feature of the
entire custom installation range is no better demonstrated than by
the CCM663SR ceiling speaker. It marries a woven
Aramid Fibre coned
twin voice-coil 150mm (6in) bass/midrange driver with an offset array of
two 25mm (1in) soft dome tweeters. Thanks to its highly accurate and
natural sound,
Aramid Fibre features on our most advanced high
performance hi-fi speakers and it brings the same qualities to the
CCM663SR. 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 CCM663SR also includes a
two-position stereo/surround switch to instantly make the speaker very
suitable to be used as a surround channel.
