Performance specifications of a typi-

cal production unit shall be as follows:

Usable frequency range shall extend

from 120 Hz - 22 kHz, -10 dB. The

loudspeaker shall be available with

selectable 25/70.7/100 Volt and 16

Ohm/voice coil direct tap switch. The

frequency dividing network shall

have a crossover frequency of 5.0 kHz.

Rated power capacity of the compo-

nents and network shall be at least 20

Watts continuous RMS power and con-

form to EIA-426-B testing. Maximum

continuous output at 1 meter shall be

at least 100.5 dB.
The backcan shall be constructed of

galvanized steel with an ABS plastic

baffle. The grille shall be constructed

of painted steel. Shipped complete

with UL-listed flex conduit clamp,

color coded tile bridge (to match color-

coded backcan), grille, wire nuts,

cut-out template and paint shield,

the integrated CM42-EZs in-ceiling

speaker is engineered for high per-

formance and rapid installation in

plenum spaces. The CM42-EZs incor-

porates a secondary attachment point

for added security, or where required

by code.
Installation for the CM42-EZs shall be

by 2-screw blind-mount constant-ten-

sion winged assembly and shall attach

to ceiling thicknesses ranging from

0.00 in to 1.50 in. The external wiring

shall be hardwired using wire nuts

accepting up to three 18-gauge wires.
The CM42-EZs is factory preset to

the 20 Watt setting in the 70.7 Volt

mode with a tap switch located on the

Independent Data
Acquisition & Verification

All data for SoundTube speakers is

independently collected from and veri-

fied by NWAA Labs (www.nwaalabs.

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.

Architectural Specifications

The loudspeaker shall consist of one

102 mm (4 in) low-frequency trans-

ducer and one 19 mm ( 0.75 in) high-

frequency transducer with a frequency

dividing network installed in a sealed

enclosure. The low-frequency voice

coil diameter shall be 13 mm (0.50 in).

The low-frequency transducer shall

have a treated fiber cone material with

cloth surround. The high-frequency

transducer shall be constructed of silk

material using a balanced-dome con-

figuration.
