Description
The CM42-EZs is a 4” coaxial 2-way
blind-mount in-ceiling speaker which
delivers true high efficiency and perfor-
mance across the operating bandwidth.
By incorporating a 4" treated-fiber driver
with cloth surround in a sealed drawn
steel backcan, this speaker delivers maxi-
mum frequency response (125 Hz – 22
kHz, - 10 dB) in a compact 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, stocking
and installation, this series includes a
color-coded (green) tile bridge, optional
pre-construction bracket, and a 5-posi-
tion tap switch for 25, 70.7 & 100 V appli-
cations with voice coil/16 Ohm bypass.
