The 8 ohm speaker features a 3" (7.6 cm) full-range driver and tuned bass port, a frequency response of 75 Hz to 18 kHz, and a power rating of 15 watts continuous pink noise, 30 watts continuous program capacity.

Its enclosure measures less than 4" (10.2 cm) deep. SpeedMount is a concealed mounting system designed to speed up installation. During rough-in, electrical contractors can install a 0° or 10° 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 suitable for small to medium classrooms and conference rooms where surface mount speakers are desired, but wall space for speaker placement is limited.

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° mounting plate, the SM 3 protrudes less than 4" from the wall to comply with ADA requirements on protrusion limits.

The SM 3 is sold in pairs and is available in a black or white finish, and includes a five year parts and labour warranty.
