Description
The CM590i is a high-powered 5.25”
2-way loudspeaker in a ported in-ceiling
enclosure design. The CM590i incorporates
a low-profile grille, proprietary HP5TM
motor-board and 6-position tap switch
with voice coil/8 Ohm direct. A tile bridge
is included and the speaker features a fast-
action SpeedWingTM for easy and secure
installation.

Applications
Engineered for high-SPL and effective
low-end response (69 Hz @ - 10 dB), the
CM590i delivers consistent high-perfor-
mance music and paging for applications
requiring longer throw or higher volume
above the existing ambient noise level. The
CM590i is ideal for in-ceiling sound rein-
forcement/PA in applications with high
ambient noise levels including casinos,
warehouses, airports, transportation & ship-
ping centers, schools, gyms, arenas and sta-
diums. For additional bass down to 43 Hz
(-10 dB) the CM801i subwoofer may be used.

be a 4-pin, 5 mm Euroblock for 8 Ohm or
distributed systems and shall accept from
10 – 22 gauge wire.
Useable frequency response shall
extend from 69 Hz – 22 kHz (-10 dB,
All performance data acquired at
SoundTube’s Technical Measurement
Center (TMC) are analyzed using a
variety of standard measurement tech-
niques, including Measured Length
Sequence (MLS) and Time Delay Spec-
trometry (TDS). Performance, develop-
ment and data acquisition tools include:
Gold Line TEF 20, CLIO, LMS, LEAP, and
proprietary modeling software. EASE™
data are acquired through an automated
TEF 20/Outline/EASE™ interface.

Measured sensitivity (2.83 Volt input,
1 meter) shall be at least 90 dB. The
speaker shall have a nominal imped-
ance of 8 Ohms and shall be available
for 25/70.7/100 Volt modes with voice
coil/8 Ohm direct. The frequency-
dividing network shall have a cross-
over frequency of 3 kHz with a slope
of 12 dB per octave (second order)
for the high-pass filter. Rated power
capacity shall be at least 80 Watts con-
tinuous power (RMS), and conforms to
EIA-426-B testing. Maximum continu-
ous output at 1 meter shall be 109 dB.

by 271.9 mm (10.71 in) in diameter. The
backcan shall be construction of alumi-
num and affixed to an ABS baffle.
EASE™ Data – 3-D polar plots.
The system shall include a 16-guage
galvanized steel support backing plate
(tile bridge) to reinforce the ceiling mate-
rial and tile support rails. The maximum
tile bridge dimensions shall be no more
than 600.1 mm (23.61 in) in length by 323.9
mm (12.75 in) in width and 11 mm (0.41 in)
in thickness with a 228.6 mm (9.0 in) diam-
eter cutout for speaker mounting.
SoundTubeSPEC™ – Proprietary
SoundTube speaker placement software.
The low-frequency transducer shall
have a polypropylene cone with butyl rub-
ber surround. The high-frequency trans-
ducer shall be constructed of aluminum
material and incorporate a high-SPL horn.
Architectural Specifications
The loudspeaker shall consist of a
133 mm (5.25 in) low-frequency trans-
ducer and a 25 mm (1 in) high-frequency
transducer with a frequency-dividing
network installed in a ported enclosure.
The low-frequency voice coil diameter
shall be 25 mm (1 in).
Installation for the CM590i shall be by
2-screw, blind-mount, constant-tension
winged assembly and shall attach to
ceiling thickness tolerances ranging
from 6.4 mm (0.25 in) to 42.9 mm (1.69
in). The fixed-wing assembly shall be
The grille shall be constructed of an ABS
bezel and iridite-plated, powder-coated
steel for lasting performance. The affixed
grille and bezel shall be mounted to the
speaker enclosure (backcan) via neo-
