Designed for in-ceiling background to
foreground SPL applications, the CM800i
delivers a broad dispersion pattern (1 kHz
– 10 kHz, EASE™ documented), true low-
end 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, casi-
nos, corporate venues, churches and other
in-ceiling applications requiring back-
ground to foreground SPL. For applica-
tions where additional bass is required,
SoundTube’s CM801i 8” subwoofer pro-
vides low-end response down to 43 Hz.

BroadBeam11
®
Wide
Dispersion Technology
More than 3 years in development,
SoundTube’s proprietary BroadBeam11®
technology incorporates a high-frequency
waveguide mated to a 1” convex alumi-
num tweeter. The BroadBeam11® high-
frequency waveguide delivers a consistent
dispersion pattern across the upper reg-
isters 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.
