Niles Audio CM610, CM630 dimensions New Construction Installation, Unpacking And Final Installation

3.Cut a foot-long piece of coat hanger. Bend the wire (creating a right angle) leaving 4-1/2” at one end (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 3-7/8” of depth. If the wire’s movement is obstructed by anything, fill the hole(s) with spackle and try another location.

4.If the coat hanger moves freely in a complete circle and you have sufficient depth, hold the template up to the ceiling surface. The cardboard square with the circular hole is the template. The inner perforated circle within the larger circle that was removed in step 1 earlier is the paint mask. Keep it for painting the loudspeaker later. Outline the circular cutout on the ceiling surface lightly with a pencil. Drill the starting point of your cut 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.

IMPORTANT: BE VERY CAREFUL NOT TO SAW THROUGH EXISTING WIRES, PIPES, OR STRUCTURE.

IF YOU FEEL EXTRA RESISTANCE AS YOU ARE CUTTING, STOP.

NEW CONSTRUCTION INSTALLATION

INSULATING THE WALL CAVITY

If feasible, fill the wall cavity with insulation at this point.

MOUNTING THE NEW CONSTRUCTION BRACKET

The optional CM600 BKT can be used with the CM610 or CM630. The hole saving bracket enables a faster and cleaner final installation of the loudspeaker. It forces the drywall installer to cut out the loudspeaker hole for you and provides wire ties for the loudspeaker wire, reducing the risks of accidental loss or movement of the wire. In addition, it enables you to align your loudspeakers with other ceiling fixtures with great accuracy since you can really see exactly where the loudspeaker will be. To install the bracket, first pivot the long wing out until it stops, which will be in straight line with the short wing. The wings and brackets have centering lines to simplify placement of the loudspeakers. Screw one side of the assembled bracket with wings to the joist using one of the supplied screws. Level the bracket. Screw the other side of the bracket/wing assembly to the joist. Two screws on each side make for a very secure installation. Secure the wire to the bracket using bracket’s wire tie tab. The drywall installers will cut the drywall to the exact size of the bracket. (See Figure 2)

CONCEALING LOUDSPEAKER WIRE FOR A FUTURE INSTALLATION

Attach the loudspeaker wire in a loop between the ceiling joists and carefully mark the exact location of the wire on a set of plans. Ask the general contractor to inform the drywall installers that the loudspeaker wire loops are concealed for future installations.

UNPACKING AND FINAL INSTALLATION

1.Remove the top piece of stryofoam from the box. You will find two loudspeakers bagged in a lower portion of packing. Remove the loudspeaker from the bag. The metal grille is installed on the loudspeaker and will need to be removed. This is easily done by rotating the mounting ‘dogs’ out with your fingers and pulling them towards the front of the loudspeaker. This will push the screw heads against the inside of the grille to work it out of the baffle. A pair of plastic grilles is also included in the packing. These may be used in place of the metal grilles to give the loudspeaker the appearance of a light fixture. (See Figure 3)

2.At each loudspeaker location, route the wire to the input connectors, then separate the loudspeaker wire so that at least 2 inches of each conductor are free. Strip away 1/4 inch of insulation from each individual loudspeaker wire.

3.Press down each spring-loaded connector one at a time, insert the appropriate conductor and then release the connector. Check to be sure that the connector is making contact with stripped wire and not the wire jacket. Gently tug on the loudspeaker wire to make sure it is held in place. If not, repeat this procedure until it is.

IMPORTANT: OBSERVE CORRECT POLARITY: POSITIVE (+) GOES TO THE RED POST AND NEGATIVE (–) GOES TO THE BLACK POST.

4.Rotate dogs back to their original positions so that they do not protrude out from the diameter of the loudspeaker.

5.Insert the loudspeaker into the hole by carefully holding it with both hands and angling it slowly into the hole until the frame is flush with the ceiling. Holding it in place carefully with one hand, (do not push against the woofer or tweeter) use a cordless drill to begin mounting the loudspeaker.

6.Tighten the four screws using a #2 Phillips bit. Use low torque and low speed or you may damage the loudspeaker. This should pull the frame and mounting dog 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.
