Description
Inputs
Colors
The CM800i is an 8” 2-way blind-mount
in-ceiling speaker design that delivers
extended low-end response (60 Hz) and
optimal off-axis performance (up to 10
kHz, EASE™ documented). SoundTube’s
proprietary BroadBeam11® waveguide
tweeter system delivers consistent high-
performance audio across the operating
bandwidth. The CM800i speaker design
incorporates a low-profile grille, propri-
etary M8™ motor-board and 6-position
tap switch with voice coil/8 Ohm direct.
Mounting hardware is included & features
a fast & secure constant tension fixed-wing
mounting system.
