delivers a broad dispersion pattern (1 kHz
– 10 kHz, EASE
™
documented), true lowend response (60 Hz, -10 dB) and high
sensitivity (93.5 dB 1W/1M). The CM800i
is ideal for nightclubs, bars, fitness centers,
hotel, airports, convention centers, casinos, corporate venues, churches and other
in-ceiling applications requiring background to foreground SPL. For applications where additional bass is required,
SoundTube’s CM801i 8” subwoofer provides low-end response down to 43 Hz.

More than 3 years in development,
SoundTube’s proprietary BroadBeam11
technology incorporates a high-frequency
waveguide mated to a 1” convex aluminum tweeter. The BroadBeam11
frequency waveguide delivers a consistent
dispersion pattern across the upper registers of the frequency spectrum (up to
10 kHz, EASE™ documented). The result
is an audio system with fewer speakers,
reduced power needs, shorter installation
time and cost savings on shipping & labor.

Architectural Specifications
The loudspeaker shall consist of a 203
mm (8.0 in) low-frequency transducer and
a 25 mm (1.0 in) high-frequency transducer with a crossover network installed
in the ported enclosure. The low-frequency voice coil diameter shall be 30.4
mm (1.2 in).
Performance specifications of a typical
production unit shall be as follows: Useable frequency response shall extend from
60 Hz – 22 kHz (-10 dB, half space, no
external equalization). Measured sensitivity (2.83 Volt input, 1 meter) shall be

low & high pass filters. Rated power
capacity shall be at least 125 Watts continuous power (RMS) and conform to
EIA-426-B testing. Maximum continuous
output at 1 meter shall be 114.5 dB.
Installation for the CM800i shall be

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 constructed of glass filled
ABS material. The external wiring input
connector shall be a 4-pin, 5 mm Euroblock
for 8 Ohm or distributed systems and shall
accept from 10 – 22 gauge wire.
The maximum backcan dimensions
shall be no more than 201.7 mm (7.94 in) in
height by 296.7 mm (11.68 in) in diameter.
