TEPS TO INSTALLING

English Français NederlandsDeutsch Italiano

Testing the space behind the hole

7LSYou need a tape measure and a sturdy wire (such as a straightened coat hanger)

22 in. (55.9 cm) in length for this step.

1. Bend the wire as shown in Figure 10.

7LS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 any 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

in. (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 11). Probe to make

sure nothing is in the way to a depth of 4

in. (10.5 cm). This indicates that the space

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

• If the wire goes in without a problem, proceed to step 4, below.

• 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 12 on page 12, 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.
