Description
The CM500i is a 5.25” 2-way blind-mount
in-ceiling speaker that delivers effective
low-end response (55 Hz) and optimal off-
axis performance (up to 10 kHz, EASE
™
documented). SoundTube’s proprietary
BroadBeam
®
waveguide tweeter system
delivers consistent high-performance
audio across the operating bandwidth.
The CM500i speaker design incorporates a
low-profile grille, proprietary M5
™
motor-
board, 6-position tap switch with voice
coil/8 Ohm direct. Mounting hardware is
included & features a fast & secure con-
stant-tension fixed-wing mounting system.
