B&W Speakers > Inwall > CCM 663SR

A high-performance, in-ceiling surround speaker that’s ideal for the surround sound channel in a home theatre set-up, or for bringing stereo sound to rooms where space is limited. The speaker brings together a twin voice-coil 150mm (6in) Kevlar bass/midrange driver with two 25mm (1in) soft dome tweeters. This combines the stereo signal, allowing the use of just one ceiling speaker without the loss of one audio channel. The speaker can be changed from stereo to surround sound mode at the flick of a switch.
