Details
The CM52s-BGM is a 5.25" coaxial two-way blind-mount, short can, 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 0.75" silk dome tweeter in a drawn steel backcan 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 100V applications with a transformer bypass position.- Features
