Bowers & Wilkins 2-way ceiling speaker

One ceiling speaker for stereo. CCM 646S is a dual, 2-way ceiling speaker featuring a 165mm (6½ in) twin voice coil, woven glass fibre cone bass/midrange driver and two offset Ultra-12 tweeters in a chassis incorporating simple and effective swing- out dog fixings. The twin voice coil bass/midrange driver and tweeters allow a stereo signal to be combined to facilitate the use of just one ceiling speaker in a single installation area without the loss of one audio channel.
