The Sound Advance® CM860 and CM660 are extended bandwidth, wide dispersion loudspeakers designed for ceiling mounting in commercial/professional installations in airports, hotels, boardrooms, cruise ships, casinos, convention centres, restaurants, offices, houses of worship and retail stores. The CM860 and CM660 incorporate polypropylene cone woofers and cloth dome tweeters that ensure superior-quality sound in foreground music, public address and paging applications. Both models feature wide dispersion (120° conical) that allows larger areas to be adequately covered by fewer speakers. An integrated, deep-drawn steel backcan and integrated RotoLock® clamps allow the CM860 and CM660 to be installed without access behind the ceiling. The baffles are constructed from fire-rated ABS that meets UL94V-0. The perforated aluminum grilles are weather-resistant and can be painted to match the installation surroundings. Connection is made via a quick-connect terminal with loop-thru. The CM860 and CM660 are shipped with a C-shaped support plate that reinforces the ceiling material, and tile support rails that can be installed without access behind the ceiling. The CM860 and CM660 are transformer-coupled, with 60W, 30W, 15W 7.5W taps and 8-ohm bypass that are selectable from the speaker’s front baffle.
