WMQ™ Wall Speaker Installation Instructions  
for the 850/880iR Receiver/Amplifier

Speaker Placement  
Step 1: Selecting Speaker  
Mounting Locations

Four WMQ Wall Speakers are ideal in rooms up to 1600  
square feet with a ceiling height of 8–12 feet.

Before starting the system installation, speaker placement  
needs to be decided. Optimum sound pattern is achieved  
when the speakers are staggered on the four walls as  
shown in figure 1. Speakers should NOT be placed directly  
opposite of each other.  
Ceiling height determines how high the speaker is set on  
the wall. Increased ceiling height allows the speakers to  
cover a larger area.  
WMQ Speakers  
If the classroom is not rectangular, does not have suspend-  
ed ceilings, or has a ceiling that is not horizontal (flat), call  
LightSPEED Technical Support (800.732.8999) to determine  
optimum speaker placement.  
Step 2: Mounting the Speakers

Installing the Speaker  
C. Use the bracket as a template to mark the position for  
the two screws where the bracket will be fastened (see  
figure 2). Keeping the bracket as horizontal as possible,  
push a sharp object through the template into the wall.  
These mark where the wall mounting screws will  
be placed.

D. Each speaker bracket comes with two mounting screws,  
two washers and two sheet rock mollies.  
i. If the walls are wood, screw the mounting bracket  
to the wall with two mounting screws and washers at  
the marked spacing. Then screws should be inserted  
into the wood so that the bracket is held snuggly to  
the wall.

ii. If the walls are sheet rock, drill pilot holes (3/16”  
to 1/4” diameter) in the sheet rock at the marked  
spacing. Screw the two sheet rock mollies into the  
pilot holes until they are flush with the surface.  
The screws and washers should be inserted into the  
mollies so that the bracket is held snugly to the wall.
