The CM650BG ceiling mount loudspeaker offers Niles durability and installation ease and is designed for unobtrusive installations.

The CM650BG measures 9-1/4 diameter; It features a weather-resistant 6-1/2 inch polypropylene co-axial driver system with a urethane surround and powder coated aluminum grilles, making it suitable for bathroom and outdoor patio applications. It employs a bracketless

mounting system: simply cut a hole in the mounting surface and tighten the four clamps via front-baffle screws. The flush, MicroPerf

INSTALLATION AND OPERATION GUIDE

Thank you for choosing a Niles Ceiling Mount loudspeaker. With proper installation and operation, you’ll enjoy years of trouble-free use.

CONTINUED OTHER SIDE

The CM650BG is designed to work well in any standard ceiling. The mounting surface must be at least 3/8 inch thick.

It will perform well in any air volume greater than .5 cubic feet.

This speaker is designed to be minimally affected by long lengths of speaker wire.

The CM650BG will accommodate speaker wire between 12 and 22 gauge.

WIRING CONSIDERATIONS

1. Cut a foot-long piece of coat hanger.

Bend the wire (creating a right angle) leaving 4-3/4” at one end for the CM-650BG (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 3-3/8” of depth. If the coat hanger movement is obstructed by anything, fill the hole(s) with spackle and try another location. (See Figure 1).

2. Locate the hole template and remove the inside portion of it. Save this part—it may be used as a paint mask. Use the inside of the template to trace the outlines at the desired location on the ceiling or wall. With a keyhole saw, cut along the penciled lines.

BE CAREFUL NOT TO CUT THROUGH ANY EXISTING WIRING.

3. Attach the speaker wires to the speaker.

Be sure that proper phasing is observed.

4. There are four clamps which hold each speaker in place. The clamps are tightened via four front-baffle screws. To install the speaker, first rotate the clamps inward. Insert the speaker into the cutout and tighten the clamps by turning the

screws clockwise. DO NOT OVER TIGHTEN THESE SCREWS. Over-tightening the clamps may make the grille difficult to install. (See Figure 2).

NOTE: The screws will be easier to turn if you “prime” them first. Before installing each speaker, turn the screws in and then turn them back out to their original positions.

5. Install the grille into the speaker. The

grilles fit tightly. This is to prevent each grille from becoming loose over time. Some effort and care is required when installing them.

6. Repeat this procedure for the next speaker.

To remove the grille from the CM650BG, obtain a small paper clip (size #1, common) and bend the last quarter inch of it into an “L” shape. Holding the paper clip with a pair of pli-

ers, insert the end with the “L” into a hole near the edge of the grille. Remove the grille by pulling the paper clip towards you.

The CM650BG may be painted. The plastic will readily accept most any kind of paint.

The speakers must be masked prior to painting them. The inside portion of the hole template can be used as a paint mask. Remove the outside portion of the template by gently pulling along the perforation. Affix the mask to the front of the speaker using a piece of tape.

Fold the tape onto itself to form a doublesided loop. Affix the tape to the tweeter and place the mask onto the speaker.

The grilles should be painted before they are installed. The best results will be obtained by using a spray gun or airless sprayer, thinning the paint (prevents clogging of grille holes) and by applying several light coats instead of one heavy one.
