If you encounter insulation behind the wall
You can expect to find insulation in an exterior wall and sometimes in an interior wall. If the
insulation found there is malleable, you can cut and remove some of it from both above and
below the speaker hole to make room for the speaker. Other types of insulation will be difficult
or possibly dangerous to handle.
CAUTION: Beware of hidden nails when reaching into the wall to remove insulation.
CAUTION: Wear gloves and protection for your mouth, nose, and eyes before handling
insulation that contains fiberglass.
Reorienting or changing speaker frames
Reorienting the rectangular frame logo
If you intend to mount a rectangular framed speaker upside-down due to a lack of space
below the hole, you will need to reorient the logo before inserting it into the hole.
To do this, remove the frame from the speaker, rotate it 180°, and reattach the frame. There
are four frame screws, labeled GRILLE, that hold the frame in place (See Figure 17 below and
Figure 23 on page 18). Do not confuse them with the dogleg clamp screws that are labeled
WALL.
Do not insert the speaker into the wall without a frame attached. The frame keeps the
speaker from falling into the wall.

Replacing the rectangular
speaker frame with the
round frame
Installing round speaker frames
If you intend to use round speaker frames, install them now by removing the four screws that
hold each rectangular frame and using them to secure the round frames (Figure 17). The logo
is on the round speaker grille, which will be positioned later.
Insert and wire the speaker
You need a Phillips-head screwdriver and optional tape to complete this step.
If your wall is not pre-wired, refer to “What to do when the room is not pre-wired” on page 24.
When wire is within reach of the hole you have cut, follow the procedure below:
1. From inside the newly cut speaker hole, locate and pull out 14 in. (36 cm) or more of the
pre-wired speaker cord (Figure 18 on page 16).
