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.

Independent Data
Acquisition & Verification
Performance specifications of a typi-
cal production unit shall be as follows:
Usable frequency range shall extend
from 45 Hz - 22 kHz, -10 dB. The loud-
speaker shall be available with select-
able 25/70.7/100 Volt and 16 Ohm/
voice coil direct tap switch. The fre-
quency dividing network shall have a
crossover frequency of 5.0 kHz. Rated
power capacity of the components and
network shall be at least 64 Watts con-
tinuous RMS power and conform to
EIA-426-B testing. Maximum continu-
ous output at 1 meter shall be at least
109.4 dB.
All data for SoundTube speakers is
independently collected from and veri-
com) using their proprietary MACH
testing system. All data is collected and
analysed according to ASTM, ISO and
AES standards using EASERA, TEF and
MLSSA. Full balloon data including
both phase and magnitude is compiled
into a variety of formats including EASE
4.x, GLL and CLF.
Installation for the CM82-EZ shall
be by 2-screw blind-mount constant-
tension winged assembly and shall
attach to ceiling thicknesses ranging
from 0.04 in to 1.6 in. The external wir-
ing shall be hardwired using wire nuts
accepting up to three 18-gauge wire.
The CM82-EZ is factory preset to the
64 Watt setting in the 70.7 Volt operat-
ing mode, with a tap switch located on
the front baffle. The system shall be
the SoundTube CM82-EZ for both low
& high impedance applications.
