Architectural Specifications
The loudspeaker shall consist of a
203 mm (8 in) low-frequency trans-
ducer and one 25 mm (1 in) high-fre-
quency transducer with a frequency
dividing network installed in a sealed
enclosure. The low-frequency voice
coil diameter shall be 25 mm (1 in).
Performance specifications of a
typical production unit shall be as
follows: Usable frequency range shall
extend from 54 Hz - 22 kHz. The
loudspeaker shall be available with
selectable 25/70.7/100 Volt and 8 Ohm/
voice coil direct tap switch. The fre-
quency-dividing network shall have a
crossover frequency of 5.6 kHz. Rated
power capacity of the components and
network shall be at least 40 Watts con-
tinuous RMS power.
Designed for both 25/70.7/100 Volt
and 8 Ohm/voice coil direct applica-
tions, the CM-EZ-II is factory preset to
the 70.7 at 20 Watts operating mode,
with a tap switch located on the back-
can.
The backcan shall be constructed of
zinc-plated steel with an ABS plastic
bezel. The grille shall be constructed
of powder-coated steel. The low-fre-
quency transducer shall have a poly-
propylene cone material with butyl
rubber surround. The high-frequency
transducer shall be constructed of
polypropylene material using a bal-
anced-dome configuration.
Packaged complete with UL-listed
flex conduit clamp, tile bridge, grille,
cut-out template and paint shield,
the integrated CM-EZ-II open-ceiling
speaker is engineered for high per-
formance and rapid installation in
plenum spaces. The CM-EZ-II incor-
porates a secondary attachment bolt
for added security, or where required
by code.
The CM-EZ-II installation shall be
by 4-point blind-mount system using
spring-loaded cams and a tile bridge.
The CM-EZ-II’s spring-loaded cams are
adaptable to stable surfaces including
drop tile and sheetrock with mate-
rial thicknesses ranging from 1/2 in
(12.70 mm) to 3/4 in (19.05 mm). For
