TEPS TO INSTALLING

English Français NederlandsDeutsch Italiano

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).
