The CM690i is a premium 6.5” 2-way,  
in-ceiling, high-efficiency, high-SPL  
loudspeaker for distributed or 8 Ohm  
applications. The CM690i incorporates  
a dedicated 6.5” treated fiber driver and  
high-power compression transducer with  
a BroadBeamHP® waveguide to deliver a  
consistent dispersion pattern and superb  
intelligibility for the foreground music,  
sound reinforcement and PA markets. The  
CM690i incorporates a 66 Watt transformer  
with a 6-position tap switch and voice  
coil/8 Ohm direct position. Mounting  
hardware and tile-bridge are included and  
feature a fast and secure constant-tension  
fixed wing mounting system.
