The CM82-EZs is an 8-inch, coaxial, two-way, blind-mount, in-ceiling speaker which delivers true high efficiency and performance across the operating bandwidth. By incorporating an 8-inch polypropylene driver with a butyl rubber surround in a sealed drawn steel backcan, this speaker delivers maximum frequency response (82 Hz 22 kHz, - 10 dB) in an integrated enclosure design. Developed specifically for paging and background music applications where cost, quality and fit are paramount, the CM82-EZs is ideal for hotels, education, hospitals, retail stores, restaurants, airports, churches or boardrooms. Indeed, the entire CM-EZ series is engineered for installations where high efficiency and rapid installation are critical attributes. For applications requiring additional bass response, SoundTube's CM1001d-T and SM1001p subwoofers provide true low-end response down to 41 Hz.
