Applications
Developed specifically for the pag-
ing and background music applica-
tions where cost, quality and fit are
paramount, the CM82-EZ is ideal for
hotels, retail stores, restaurants, airports,
churches (under eave) or boardrooms.
Indeed, the entire CM-EZ series is engi-
neered for installations where high-effi-
ciency and rapid installation are critical
attributes. For applications requiring
additional bass response, SoundTube’s
CM1001d subwoofer provides true low-
end response down to 50 Hz.
