Installed Sound Products

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.
