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 Entertain-
ment or at www.soundtube.com.
Data Acquisition
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.
EASE™ Data – 3-D polar plots.
SoundTubeSPEC™ – Proprietary
SoundTube speaker placement software.
Architectural Specifications
The loudspeaker shall consist of a 203
mm (8 in) low-frequency transducer and
a high frequency transducer with a 1”
exit and a frequency-dividing network
installed in a ported enclosure. The low-
frequency voice coil diameter shall be 34
mm (1.36 in).
The performance specifications of a
typical production unit shall be as fol-

lows: Useable frequency response shall
extend from 63 Hz – 20 kHz (-10 dB, no
external equalization). Measured sensitiv-
ity (2.83 Volt input, 1 meter) shall be at
least 95 dB. The speaker shall have a nomi-
nal impedance of 8 Ohms and available
for 25/70.7/100 Volt modes with a voice
coil/8 Ohm direct. The frequency-dividing
network shall have a crossover frequency
of 2.4 kHz with a slope of 12 dB per octave
(2nd order). Rated power capacity shall
be at least 125 Watts continuous power
(RMS), and shall conform to EIA-426-B
testing. Maximum continuous output at 1
meter shall be 116 dB.
The low-frequency transducer shall
have a treated fiber cone and cloth sur-
round.
Installation for the CM890i shall be
by 2-screw blind mount, constant ten-
sion 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 external wiring input connector
shall be a 4-pin, 5 mm Euroblock connec-
tor for 8 Ohm or distributed systems and
shall accept from 10 – 22 gauge wire. The
maximum backcan dimension shall be
no more than 201.7 mm (7.94 in) in height
