TWEETER (DUAL)  
CM Stereo Input speakers are ideal for  
locations where a stationary “sweet spot”  
is impossible or impractical such as hall-  
ways or entryways. They also deliver  
quality two-channel sound in locations  
that only have enough space to accom-  
modate a single speaker such as an  
enclosed shower.  
CM Stereo Input loudspeakers are  
designed to deliver stereo sound from a  
single speaker. Dual tweeters housed in a  
stereo imaging faceplate deliver left and  
right channels (stereo) while a dual voice-  
coil woofer mechanically sums both left  
and right channels, creating a convincing  
illusion of stereo through a single speaker.

INSTALLATION PROCEDURE  
1. Cut a foot-long piece of coat hanger.  
Bend the wire (creating a right angle)  
leaving 4-3/4” (5-3/8" for the CM8.5SI)  
at one end (this allows for the extra  
width of the mounting dogs). Poke the  
“L-shaped” wire into the pilot hole and  
turn it in a complete circle and move it  
into the ceiling cavity to make sure you  
have approximately 4” of depth. If the  
coat hanger movement is obstructed by  
anything, fill the hole(s) with spackle  
and try another location (See Figure 1).
