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
application. For easy ordering, stock-
25 V Output
