TEPS TO INSTALLING
English Français NederlandsDeutsch Italiano
Passing the pilot hole test
If you have successfully determined that this location will work for one speaker, test the wall
or ceiling for the second speaker before making any larger holes. Refer to “Drill a pilot hole for
testing the wall space” on page 9 and repeat those steps.
If the first speaker location is fine, but the second is not, you may want to relocate both
speakers.
Repairing a pilot hole
To patch a pilot hole, fill it with spackle. Let the spackle dry, then add more until the hole is
slightly overfilled. When it is thoroughly dry, sand the area to make it flush with the wall.
Prepare the wall for inserting the speaker
Use care in the steps that follow to ensure satisfaction with the end result.
CAUTION:
Now is a good time to reconsider your comfort level with this job. If you have doubts
about cutting into or running cord behind the wall, it is best to stop here. Contact a professional
installer, describe the job, and request a cost estimate before engaging the installer’s services.
WARNING:
If you believe insulation in a wall may contain asbestos, do not cut into the wall. Find
a different location for installing the speakers instead.
Measure and mark the hole to be cut
You need a carpenter’s level, a sharp pencil, and optional tape with the template to
complete this step.
1. Position the template carefully over the pilot hole where you want to install one speaker.
2. Make sure the template is level (Figure 14).
