Applications
Developed specifically for the pag-
ing and background music applications
where cost, quality and fit are para-
mount, the CM42-EZs 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.
