Using a spade bit with the

power drill to create the

pilot hole

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).

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.
