Applications
Designed for in-ceiling background
to mid-level SPL applications, the
CM500i is ideal for music & paging
in courthouses, schools, retail stores,
grocery, restaurants, hotels, casinos,
museums, conference rooms &
churches. For applications where addi-
tional bass is required, SoundTube’s
CM801i 8” subwoofer provides low-end
response down to 43 Hz.
BroadBeam
®
Wide
Dispersion Technology
More than 3 years in development,
SoundTube’s proprietary BroadBeam
®
technology incorporates a high-fre-
quency waveguide mated to a 1” convex
aluminum tweeter. The BroadBeam
®
high-frequency waveguide delivers a
consistent dispersion pattern across
the upper registers of the frequency
spectrum (up to 10 kHz, EASE
™
docu-
mented). The result is an audio system
with fewer speakers, reduced power
needs, shorter installation time and cost
savings on shipping & labor.
