HIGH-QUALITY, IN-CEILING SPEAKERS
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
centers, 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.

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.

Architects and Engineers Specification:
The loudspeaker shall be of the two-way type comprising a single flush-mount enclosure containing one 8" (203mm) [6½” (165mm)]
low-frequency transducer and one coaxially-mounted 1" (25mm) pivoting [non-pivoting] high-frequency transducer.
Frequency response shall be 50Hz [70Hz] – 20kHz. Total power handling shall be 70 watts RMS and 140 watts program. Sensitivity
measured with 2.83 volts input at 1 meter on axis averaged between 50Hz [65Hz] – 20kHz shall be 90dB [89dB]. The unit shall be
supplied with a line matching transformer suitable for 100 volt or 70 volt with a front-mounted control allowing user-selectable power
taps of 60W, 30W, 15W, 7.5W and a 8 ohm bypass.
The backcan shall be constructed from deep-drawn steel. The baffle shall be injection molded using fire-rated ABS that meets UL94V-0.
Wire shall be terminated in an enclosed area on the rear of the backcan. Strain relief shall be provided for wire. A support hook shall
be provided on the rear of the backcan to allow additional support when necessary.
The system shall include a support backing plate to reinforce the ceiling material and tile support rails which can all be installed from
beneath the ceiling tile.
External dimensions shall be 12" (305mm) [9¾” (248mm)] in diameter x 9½" (241mm) [7½” (190mm)] mounting depth. The total
enclosure shall weigh 11 lbs. (5kg) [8 lbs. (3.63kg)] per unit.
The loudspeaker shall be the Sound Advance Prommercial CM860 [CM660].
