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 absolutely flush with the wall surface. There should be no gaps between the wall and the frame (See Figure 12).

Installation of the Speaker, Sensor and Grille in New or Existing Construction

Installing a Niles MS-1 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 knockout 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 MS-1 using its mounting hex nut and washer so that it is tightly secured to the speaker. Connect all wires and continue your installation.
