Speaker Placement
With nearly endless placement options, careful consideration for placement of the QM-615 
in-ceiling speaker needs to be considered, as installation requires cutting a hole in your 
wall or ceiling! When using the QM-615 in home theater applications follow the guidelines 
illustrated below. 
Swivel Tweeter Placement
The QM-615 has a swivel tweeter allowing sound to be directed toward or away from 
the listening area depending on the application. A tweeter aimed toward your listening 
position improves imaging and detail. When using the QM-615 as front/main home theater 
speakers or as stereo speakers in a distributed audio system, aim the tweeter toward the 
main listening position. For rear/surround speakers installed in walls or ceilings, aim the 
tweeter toward the nearest reflecting surface (an adjacent wall or ceiling) for a more 
diffuse sound field (for more direct sound, aim the tweeter at your listening position).
