Description
The CM400i is a 4” 2-way blind-mount inceiling speaker that delivers effective low-end
response (75 Hz, -10 dB) and optimal off-axis
performance (up to 10 kHz, EASE™ documented). The CM400i speaker design incorporates a low-profile grille and 5-position tap
switch with voice coil/4 Ohm direct. Mounting hardware is included & features a fast &
secure constant-tension fixed-wing mounting
system.
Applications
Designed for in-ceiling background to
mid-level SPL applications, the CM400i is
ideal for music & paging in courthouses,
schools, retail stores, grocery, restaurants,
hospitals, hotels, casinos, museums, conference rooms & churches. For applications where additional bass is required,
SoundTube’s CM1001d 10” subwoofer provides additional low-end response down to
41 Hz (-10 dB).

Technical Data and
Specification Tools
Technical Data
SoundTube Entertainment strives to
provide complete and effective technical
information and data to dealers, engineers
and designers. All data are available from
SoundTube Entertainment or at www.
soundtube.com and includes EASE™ Data
– 3-D polar plots and SoundTubeSPEC™ –
Proprietary SoundTube speaker placement
software.
Independent Data Acquisition
and Verification
All data for SoundTube speakers is independently collected from and verified by
NWAA Labs (www.nwaalabs.com) using
their proprietary MACH testing system. All
data are 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 a 102 mm
(4 in) low-frequency transducer and a 25 mm
(1.0 in) high-frequency transducer with a
crossover network installed in the enclosure.
The low-frequency voice coil diameter shall
be 19 mm (0.75 in). The low-frequency transducer shall have a polypropylene cone with
rubber surround. The high-frequency transducer shall be constructed of aluminum.
Performance specifications of a typical
production unit shall be as follows: Useable
frequency response shall extend from 75
Hz – 22 kHz (-10 dB, half space, no external
equalization). Measured sensitivity (2.83
Volt, 1 meter) shall be at least 90 dB. The
speaker shall have a nominal impedance of
4 Ohms and be available for 25, 70.7 & 100
Volt modes with voice coil/4 Ohm direct.
The frequency-dividing network shall have
a crossover frequency of 1.8 kHz with slopes
of 12 dB per octave (2nd order) for both low
& high pass filters. Rated power capacity
shall be at least 20 Watts continuous power
(RMS) and conform to EIA-426-B testing.
Maximum continuous output at 1 meter
shall be 100 dB.
Installation for the CM400i shall be by
2-screw, blind-mount, constant tension fixedwinged mounting system and shall attach
to ceiling thicknesses ranging from 0.6 mm
(0.025 in) to 47.5 mm (1.87 in). The fixed-wing
assembly shall be constructed of zinc-plated
steel. The external wiring input connector
shall be a 4-pin, 5 mm Euroblock for 4 Ohm
for distributed systems and shall accept
from 10 – 22 gauge wire.
The maximum backcan dimensions shall
be no more than 166.4 mm (6.55 in) in height
by 153.7 mm (6.05 in) in diameter. The maximum visible dimensions shall be no more
than 11.9 mm (0.47 in) in height by 207.0 mm
(8.15 in) in diameter. The backcan shall be
constructed of steel.
The grille shall be constructed of an ABS
bezel and powder-coated steel for lasting performance in the elements. The affixed grille
and bezel shall be mounted to the speaker
enclosure (backcan) via neodymium magnets
and include a tool-free seismic restraint. For
in-field painting, a paint mask is included.
The CM400i has an optional color-coded
pre-construction bracket that shall be compatible with an optional junction box. An
18-gauge wire whip, Euroblock connector
and UL cover plate shall be included with
the junction box. The maximum dimensions
of the Pre-Construction Bracket shall be no
more than 635 mm (25.0 in) in length by 381
mm (15.0 in) in width and 128 mm (5.0 in)
(includes affixed junction box) in thickness
with a 167.6 mm (6.0 in) cutout for speaker
mounting.
The system shall be the SoundTube
CM400i for both low & high impedance
applications.
