Installation of

Brackets, Frames

and Grilles in

Existing Walls

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

1. Drill a 1/8” pilot hole just barely

through the wallboard or dry wall (1/2”

to 5/8” deep in most homes) about an

inch below the center of your proposed

speaker location (an inch to the side if

you are mounting the speaker horizon-

tally). BE VERY CAREFUL NOT TO DRILL

THROUGH EXISTING WIRES, PIPES, OR

STRUCTURE. IF YOU FEEL ANY EXTRA

RESISTANCE AS YOU ARE DRILLING,

STOP. Cut a piece of coat hanger equal

to the width of the bracket. Bend the wire

in half creating a right angle. Poke the “L-

shaped” wire into the pilot hole and turn

it in a complete circle. If it turns freely,

repeat the procedure from a hole about

an inch above the center of your proposed

speaker location (See Figure 11).

If the wire’s movement is obstructed by a

pipe or cable, fill the hole (s) with spack-

le or other patching compound and try

another location.
2. When determining the final location of

the cutout keep in mind that the frame and

bracket will extend beyond the cutout.

Make sure that you do not place the edge

of the cutout directly next to a stud. Locate

the studs using a stud sensor or hand-

knocking. Once you have determined the

correct position for the cutout, hold the

supplied template up to the wall surface.

Level the template in either the horizontal

or the vertical position and mark the wall

with a

pencil. Drill the four corners

with a 1/4” drill bit.
3. If you are cutting a painted

or wall papered drywall use

a sheetrock or keyhole saw.

Cut the hole with the saw at

a 45 degree 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 ANY EXTRA RESISTANCE AS

YOU ARE CUTTING, STOP.
4. If you are cutting into lath and plaster

walls, use masking tape to outline your

penciled marks, drill the four corners with

a 1/4” bit 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. Finally, insert a metal

cutting blade into a sabre saw and very

slowly and carefully saw the lath. Sawing

the lath can easily vibrate plaster off the

wall. If you have the patience, use a pair

of tin snips to slowly nip away at the lath

instead. There is no risk with this method,

it is just time consuming.
5. Fill the wall cavity with insulation at this

point. Remember to use equal amounts of

insulation for each speaker.
6. Slip the mounting bracket through the

hole and pull it toward you so that its front

edge slides into the hole and stops in place.

7. Attach the frame to the bracket by

screwing the frame to the bracket using

the supplied screws. Do not overtighten

the screws, this will distort the frame and

the grilles will not fit (this is not perma-

nent, just loosen the screws and the grille

will pop in). The screws should pull the

frame and bracket together (sandwiching

the drywall) so that the frame is abso-

lutely flush with the wall surface. There

should be no gaps between the wall and

the frame (See Figure 12).

Speaker, Sensor

and Grille in New or

Installing a Niles MS110 MicroSensor
There is a 1/2” round molded “IR Sensor

Knockout” on the face of the speaker baf-

fle. To prevent damage to the crossover

network you must remove the knock-

out from the rear of the speaker. Do not

attempt to remove the knockout with the

speaker face up. Lay the speaker face

down on a clean carpet or rug. Put the

tip of a screwdriver into the center of the

round “knockout” and sharply tap the

screwdriver handle as necessary. Install

the MS110 using its mounting hex nut

and washer so that it is tightly secured to

the speaker. Connect all wires and con-

tinue your installation.
