CCM 646S
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. The CCM 646S also includes
three-way switchable high frequency equalisation.
