Description
The CM52-BGM-II is a 5.25" coaxial two-way blind-mount in-ceiling speaker which delivers highefficiency 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 backcan (with a tuned port), this speaker delivers maximum frequency response (56 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 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.
Features:
- One 5.25" (130 mm) polypropylene woofer with rubber surround and one .75" (19 mm) silk dome tweeter
- BroadBeam Ringª technology for mid-range clarity and ultra wide off axis performance
- Easy-access six-position tap switch for 25/70.7/100 V and transformer bypass settings allows for easy ordering, stocking and installation
- Tuned port on baffle for improved bass response down to 56 Hz (±10 dB)
- Reduced amplification costs and maximum efficiency of 83.5 dB sensitivity, 16 ? impedance
- Incorporates a steel plated and powder coated flangeless magnetic grille for lasting durability and seamless aesthetic (White grille included, but also available in Black)
- Adaptable to material thicknesses ranging from 0.035" (0.9 mm) to 1.6" (40.6 mm)
- UL 1480 and 2043 approved
- High-quality black or white painted finish.
- Included accessories: tile bridge, UL listed 0.5 inch conduit clamp
- Optional accessories: Color-coded (green) preconstruction bracket (AC-CMEZ-6/8-PCB) Black Grill (GRL-CM-BGM-II-BK)
