The SMS series surface mount loudspeakers are appropriate for background music and voice reinforcement in applications where high sonic performance is demanded. Compatible with both 70/100 V systems and direct drive parallel systems, the SMS systems are well suited for conference rooms, auditoria, convention centers, airports, shopping centers, restaurants and entertainment fill applications. They are compatible with the CMS series ceiling mount speakers and provide a consistent sound quality when used together. The K-lock mounting system allows the mounting bracket to be pre-installed, pre-wired, pre-tested for correct wiring, pre-aimed and locked down and then protected from paint and dust until the project site is suitable for loudspeaker installation. The addition of the loudspeaker at the end of the project takes seconds and most of the system test can already be complete.

The sensitivity of the loudspeaker shall produce 91 dB SPL in half space with a power input of 1 Watt. The frequency response shall extend down to 85 Hz at –3 dB on axis. The peak SPL shall be 113 dB and the loudspeaker shall handle a peak power of 160 Watts, 80 Watts program when the transformer is bypassed. The speaker shall be mounted using a bracket integrating both electrical and mechanical connections in one unit. The mounting bracket may be mounted to the wall, electrically terminated, pre-tested and protected against dust and paint with the included cover before actual speaker installation.
