SM 26 • Setup Guide (Continued)

NOTE:

 

A speaker wire access hole (see the following figures) must also be cut in the wall, so mark that hole location now 
with the mounting plate positioned on the wall while ensuring that the wall stud does not interfere with the wire 
routing and that the mounting plate hides the access hole.

3. 

Drill the mounting plate pilot holes and cut the speaker wire access hole, as previously marked.

4. 

Install the speaker cables into the wall before installing the speaker mounting plate. Leave enough slack in the cable.

5. 

If using the 10° mounting adapter, route the speaker cable through the adapter and  0° mounting plate, and attach the 
adapter to the 0° mounting plate using the four included screws and washers, as shown below.

6. 

Route the speaker cable through the rear of the mounting plate and attach the wire ends to the quick connect contacts using 
a small screwdriver, as shown below. Be sure to observe the correct polarity.

7. 

Attach the mounting plate to the wall, as shown below. 
 

NOTE:

  Figures below refer to steps 5 through 7.
