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-

ing and installation, this series includes

a color-coded (green) tile bridge and

optional pre-construction bracket, 5-posi-

tion tap switch for 25, 70.7 & 100 V appli-

cations with voice coil/16 Ohm bypass.
