Steps to Installing

Drilling the pilot hole

You will need a half-inch spade bit and power drill, or a special rotary cutting tool for this step.

Using the proper equipment and protection is important.

WARNING: Use eye protection and be sure to observe all safety precautions while using the drill or cutting tool (Figure 15).

Figure 15

Caution against drilling without eye protection

WARNING: Make sure the spot chosen is safe for cutting. Do not cut through surfaces that may have hazards such as electrical wiring, conduits, or plumbing concealed behind them. Follow all other safety precautions.

1.Center the tip of the drill bit in the top circle you have drawn).

2.Drill completely through the wallboard to create a hole that you can probe behind.

Note: If you encounter insulation in the wall, it will be difﬁcult, if not impossible, to probe behind the pilot hole. If you are certain that the location you have chosen is free of hazards and impediments, you may choose to cut the hole for the speaker anyway, remove some of the malleable insulation, and proceed from there. Refer to “Prepare the wall for inserting the speaker” starting on page 21.

3.Drill the second hole just below the ﬁrst one (Figure 16). This elongates the hole enough to allow for testing the space for the length of the speaker enclosure.
