STEP 4  
LOUDSPEAKER PLACEMENT  
Attach loudspeakers wires to speaker terminals, observing correct  
polarity (positive to positive and negative to negative), and  
position panel and frame assembly to hole as shown. Insert top of  
mounting frame into hole at top. By moving bottom of frame  
upwards, you should now be able to insert bottom of frame into  
hole at bottom. Be careful not to pinch loudspeaker wires in the  
process. Tighten long screws. Use the integral bubble levels during  
tightening to insure straightness of final position.  
The Model 525W was designed to work within almost any interior  
decorating scheme. It can be installed in virtually any location where flush  
mounting is possible. For a quick, easy installation there are integral bubble  
levels located on the baffle to insure perfect horizontal or vertical  
alignment. Additionally, the Model 525W is magnetically shielded and  
can be safely mounted near TV’s for use in Home Theaters.  
LEFT/RIGHT FRONT SPEAKERS  
For best stereo reproduction, the two loudspeakers should be placed an  
equal distance from your listening position and separated so that the  
angle between them at the listening position is between 40 and 60  
degrees. Note: Although the speaker can be mounted either horizontally  
or vertically, the MTM design used in the Model 525W will produce a more  
evenly distributed sound throughout the listening area if mounted  
vertically.  
STEP 5  
After speaker panel is secured tightly, test for sound.  
For best stereo imaging, we recommend that the units be placed so that  
the tweeters are as close as possible to the ear level of a seated listener.  
As this is not always possible in keeping with aesthetic design of a  
particular room, the Model 525W loudspeaker is designed with a pivoting  
tweeter which rotates to allow you to “aim” the high frequencies toward  
the listening position.  
STEP 6  
When you are satisfied the speaker is operational, “aim” the  
tweeter, and affix grill. As grill is designed for a snug fit, you’ll need  
to position one edge into the slot first, and press or squeeze  
around perimeter of the grill, while pushing the leading edge into  
the grill slot.

CENTER CHANNEL  
STEP 1  
One of the most important parameters for the center channel  
placement is height. Ideally, the center channel is positioned so  
that its tweeter is on the same horizontal plane as the left/right  
speakers. This establishes a firm image height when special audio  
effects are panned from one side to the other, such as a  
speeding car moving across the screen. When a large  
discontinuity occurs between the heights of the center and  
left/right front speakers, the image of the moving object  
becomes confused and somewhat unnatural due to shifts in  
image height. Note: Although the speaker can be mounted  
either horizontally or vertically, the MTM design used in the Model  
525W will produce a more evenly distributed sound throughout  
the listening area if mounted vertically.  
Using a stud finder (available at low cost at most hardware stores)  
or other accurate method, locate center point between two  
studs and mark. Using template provided, trace hole pattern on  
surface of wall.  
STEP 2  
Using a sabre saw, keyhole saw or very sharp utility knife, cut hole  
in wall, following traced pattern.  
STEP 3  
Run loudspeaker wires to sound source location. There are several  
methods you can use to accomplish wiring, depending on the  
construction characteristics of the room or house. You can add a  
professional touch to your installation by using a speaker terminal  
plate at the source location. Leave sufficient amount of wire at  
speaker location (8 to 10 inches) to complete connection.
