Before you make any holes
Drill a pilot hole for testing the wall space
Be sure you have read and understand the considerations provided in "Preparation" starting
on page 5, so you can proceed with confidence.
Installation is basically the same, whether you are using these speakers with a rectangular
grille or round grille and installing in a wall or ceiling. There are a few exceptions.
Wherever special instructions apply to ceiling or round-faced speaker installation, those
instructions will appear in a gray box, like this.
CAUTION: If you are unsure of your ability to complete this process, contact a professional
installer.
Allow 30 to 60 minutes to complete the steps that follow.
Before you make a sizeable 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" starting on page 21. 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 for this first step
You will need a sharp pencil for this step.
The template is designed to show where to drill two half-inch (13 mm) pilot holes first, before
you make an opening large enough for the entire speaker. This allows you to probe behind the
wall to make sure your chosen location is spacious enough and there are no unseen 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 for testing the area below the
pilot hole to make sure it is spacious enough behind the 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.
For ceiling installations, carefully consider how the position of the speaker enclosure
behind the wallboard affects the orientation of the Bose
tain a consistent logo orientation, you can remove and rotate the speaker frame as needed
before inserting the speaker into the ceiling hole. See Figure 21 on page 20.
Tip: Remember to 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. This does not apply to exterior walls in cold climate regions, where upside-down
speaker installation is not recommended.
