Description

blind-mount in-ceiling speaker that deliv-
ers effective low-end response (55 Hz) and
optimal off-axis performance (up to 10 kHz,
independently verified). SoundTube's propri-
etary BroadBeam
delivers consistent high-performance audio
across the operating bandwidth. The CM500i
speaker design incorporates a low-profile
grille, proprietary M5
six-position tap switch with voice coil direct
position. Mounting hardware is included and
