Before you make any holes
Be sure you have read and understand the considerations provided in “Preparation” starting
on page 5, so you can proceed with confidence.
CAUTION: If you are unsure of your ability to complete this process, contact a professional
installer.
Small check marks call your attention to the tools you’ll need for the next step.
Tips offer ideas to make the job go easier and help you avoid mistakes.
Drill a pilot hole for testing the wall space
Before you make a large cut into the wallboard, check the space by probing behind the wall
or ceiling through a small pilot hole. Time spent now can help ensure a successful installation.
Note: If you are working in an exterior wall where there is insulation, it may be difficult to probe
behind a pilot hole. You may prefer to eliminate this step and skip ahead to “Prepare the wall for
inserting the speaker” on page 13. Do this only if you can be sure the insulation is malleable and
that nothing else behind the wall will impede the installation.
WARNING: If you believe the insulation behind the wall may be composed of asbestos,
do not drill or cut into that wall. Find a different location for the speakers instead.
Using the template
You will need a sharp pencil for this step.
The template shows where to drill two
1
/
2
in. (13 mm) pilot holes before you make an opening
large enough for the entire speaker. You can then test the space behind the hole to make sure
there is enough room for the speaker and that there are no materials blocking the installation.
Notice the dotted lines extending at an angle from the pilot hole to the bottom corners of
the DO NOT CUT area on the template. Use them as a guideline to be sure there is enough
room below the pilot hole for the length and width of the speaker enclosure.
To position the template
1.
Select a spot on the wall or ceiling where you want the center of the speaker grille. Allow
enough space for the speaker enclosure both above and below the pilot hole. You may
need that second option if you find an impediment in the space below the hole.
2.
Center the pilot-hole circles on the selected spot as you press the template to the wall.
3.
Use a pencil to trace around the inside of the circles (Figure 7).
4.
Remove the template.
