SM 26 • Setup Guide (Continued)

NOTE: A speaker wire access hole (see the following figures) must also be cut in the wall. 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.Install the mounting plate.

NOTE: Since applications can vary considerably, it is assumed that the installer will exercise good judgment when

selecting the mounting location, method, and hardware. Mounting hardware is not provided.

zz If using the 10° mounting adapter, route the speaker cable through the adapter and 0° mounting plate, attach the adapter

to the 0° mounting plate using the four included screws and washers, then attach the wire ends to the quick connect contacts using a small screwdriver. Be sure to observe the correct polarity. Attach the mounting plate to the wall (see the figure below).
