Description

The CM82-EZ is a 8” coaxial 2-way blind-mount in-ceiling speaker which delivers true high-efficiency and perfor- mance across the operating bandwidth. By incorporating a 8" polypropylene driver with a butyl rubber surround in a sealed drawn steel backcan, this speaker delivers maximum frequency response (45 Hz – 22 kHz, - 10 dB) an integrated enclosure design.

Mounting hardware is included and features a constant-tension mounting system with a 21 gauge “full-metal” steel tile bridge ensuring rapid and secure installation in any sheetrock or drop-tile
