Installation in Existing Construction

IMPORTANT: Before you cut into any wall, review the sections on running wire and speaker placement.

1.When determining the location of the speaker cutout keep in mind that the mounting dogs will extend 3/4" beyond the cutout. make sure that you do not place the edge of the cutout directly next to a ceiling joist. Locate the joists using a stud sensor or hand-knocking.

2.Once you have determined a possible position for the cutout, drill a 1/8” pilot hole just barely through the ceiling (1/2” to 5/8” deep in most homes) about an inch below the center of your proposed speaker location. BE VERY CAREFUL NOT TO DRILL THROUGH EXISTING WIRES, PIPES, OR STRUC- TURE. IF YOU FEEL ANY EXTRA RESIS- TANCE AS YOU ARE DRILLING, STOP.

3.Cut a foot-long piece of coat hanger. Bend the wire (creating a right angle) leaving 4-3/4" this allows for the extra width of the mounting dogs). Poke the “L-shaped” wire into the pilot hole and turn it in a complete circle and move it into the ceiling cavity to make sure you have approximately 6" of depth. If the wires movement is obstructed by any- thing, fill the hole(s) with spackle and try another location. (See Figure 14)

4.If the coat hanger moves freely in a complete circle, hold the supplied tem- plate up to the ceiling surface. Outline the circular cutout on the ceiling sur- face with a pencil. Drill starting point with a 1/4" bit.

Figure 14

5.If you are cutting drywall use a sheetrock or keyhole saw. Cut the hole with the saw at a 45° angle. That way, the drywall section can be replaced cleanly if there is an unseen obstruction behind the wall. BE VERY CAREFUL NOT TO SAW THROUGH EXISTING WIRES, PIPES, OR STRUCTURE. IF YOU FEEL EXTRA RESISTANCE AS YOU ARE CUTTING, STOP.

6.If you are cutting into a plaster ceiling, use masking tape to outline your pen- ciled circle and use a razor to score the plaster down to the lath beneath. Then use a chisel to remove all of the plaster within the taped outline. To actually cut the lathe, two methods are used profes- sionally; sawing with a metal cutting blade on a sabre saw is the quickest and the riskiest. Sawing a lathe with a sabre saw can easily vibrate plaster off the ceiling in a completely distant loca- tion creating more patchwork. If you have the patience, use a pair of tin snips to slowly nip away at the lath instead. There is little risk with this method, it is just time consuming.
