Bowers and Wilkins CCM664SR In-Ceiling Speaker 

Priced as a single speaker

 CCM664SR is a dual, two-way ceiling speaker combining two offset tweeters and a twin voice coil bass/midrange driver to allow either for a combined stereo signal from one speaker, or for rear-channel surround sound.

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 combination of convenience and performance that is a feature of the entire custom installation range is no better demonstrated than by the CCM664SR.
