Extron is now shipping the SM 3, a compact, fast-installing flush mount speaker featuring the Extron SpeedMount System. This 8-ohm speaker features a 3″ (7.6 cm) full-range driver and tuned bass port, a wide frequency response of 75 Hz to 18 kHz, plus a power rating of 15 watts continuous pink noise and 30 watts continuous program capacity. The enclosure for the SM 3 measures less than 4″ (10.2 cm) deep. SpeedMount is an Extron-exclusive, concealed mounting system designed to speed up installation. During rough-in, electrical contractors can install a 0-degree or 10-degree mounting plate on the wall and terminate the speaker cable to the mount’s integrated wiring contacts. Later, installers can slide the SM 3 speaker onto the mount and secure it into place with a “click,” automatically connecting to the wiring contacts on the mounting plate.

The SM 3 speaker is aimed at small to medium classrooms and conference rooms where surface mount speakers are desired, but wall space for speaker placement is limited. It provides wide frequency response and wide coverage from a compact enclosure to optimize voice intelligibility without compromising music reproduction.

A release on the speaker baffle allows for quick removal from the mount. The release is hidden and can be locked to deter theft, together with the concealed speaker wiring contacts. When used with the 0-degree mounting plate, the SM 3 protrudes less than 4″ from the wall to comply with ADA requirements on protrusion limits.
