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.
