The CM52s-BGM-II is a 5.25″ coaxial two-way blind-mount in-ceiling speaker which delivers true high-efficiency and performance across the operating bandwidth. By incorporating a 5.25″ polypropylene driver with a rubber surround and a .75″ silk dome tweeter in a drawn steel shallow backcan (3.75″) with a tuned port, this speaker delivers maximum frequency response (65 Hz – 22 kHz, ±10 dB) in an integrated enclosure design. Mounting hardware is included and features a constant-tension fixed-wing mounting system with a 21-gauge “full metal” steel tile bridge ensuring rapid and secure installation in any sheetrock or drop-tile application. For easy ordering, stocking and installation, this series includes a color-coded (green) tile bridge and optional color-coded (green) pre-construction bracket, as well as a six-position tap switch for 25, 70.7 and 100 V applications with a transformer bypass position.

Applications
Developed specifically for paging and background music applications, the CM52s-BGM-II is ideal for hotels, education, hospitals, retail stores, restaurants, airports, churches or boardrooms. Indeed, the entire CMBGM-II series is engineered for installations where high-efficiency, added bass response and rapid installation are critical attributes. For applications requiring additional bass response, SoundTube’s CM1001d subwoofer provides true low-end response down to 41 Hz.
