Steps to Installing

Testing the space behind the hole

You need a tape measure and a sturdy wire (such as a straightened coat hanger)
22 inches (55.9 cm) in length for this step.

1.

Bend the wire as shown in Figure 17.

places

Tip:

For greater accuracy, make the first bend a little long, measure again, and cut off the

extra length at that end.

WARNING:

If there is a possibility of electrical wiring in the space behind the wallboard, wrap

the wire with electrical tape to prevent electric shock.

2.

Make a mark 4

inches (10.5 cm) from the short end as an indicator of the proper front-

to-back depth of the hole.

3.

Use the bent wire to test for enough depth, front-to-back:
Insert the short end of the wire into the hole and straight back (Figure 18). Probe to make
sure nothing impedes inserting this end to a depth of 4

inches (10.5 cm). This indicates

that the space behind the wallboard is deep enough for the front-to-back speaker
dimension.

• If you cannot insert the wire to the 4

-inch (10.5 cm) mark, you need to drill a new pilot

hole elsewhere. Then repeat step 3.

4.

Use the wire again to test the width, side-to-side:
With the short end still in the hole, reposition it (as shown in Figure 19) and rotate it 360˚
around the hole. This indicates if the wall space is wide enough on each side of the hole
for the side-to-side dimension of the speaker.
