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 M5motor-  
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.
