IMPORTANT: Before you cut into any wall, review the sections on running wire and loudspeaker placement.
1.When determining the location of the loudspeaker 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
4.If the coat hanger moves freely in a complete circle, hold the supplied template up to the ceiling surface. Outline the circular cutout on the ceiling surface with a pencil. Drill starting point with a 1/4" bit.

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 penciled 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 professionally; 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 com- pletely distant location 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 con- suming.
