Description
The CM-EZ-II is a 2-way blind-mount
in-ceiling speaker. The CM-EZ-II speaker
design incorporates an 8" polypropylene
driver with rubber surround and a 7.3
liter steel backcan for extended frequency
response (54 Hz – 22 kHz, - 10 dB).
SoundTube’s integrated CM-EZ-II design
includes unique & patented blind mount
SnapCam ™ installation technology and a
21-gauge steel tile bridge ensuring rapid
and secure installation in any sheetrock
or drop-tile ceiling. For easy ordering,
stocking and installation, the CM-EZ-II
comes with a 6-position tap switch for
25, 70.7 & 100 V applications with voice
coil/8 Ohm bypass.
Applications
Engineered for general background to
foreground music & paging applications,
the CM-EZ-II is ideal for retail stores,
restaurants, airports, churches, conference
centers & boardrooms.
