7.Direct the tweeters. The tweeters are directed by gently pressing on the outer edge of the tweeter housing. It will move in any direction. For low volume background listening, create more reflections and thus more ambiance by directing the tweeters towards the sidewalls. (See Figure 4)

8.Install the MicroPerf™ grille. Start by positioning one edge of the grille slightly inside the loudspeaker. Gently work around the loudspeaker a little at a time until the grille is fully seated. Don’t try to insert the grille fully in any one area, as this will make complete installation more difficult. Don’t force the grille to fit as you may damage the grille if you apply too much force.

9.Connect the other end of each loudspeaker wire to the receiver (or amplifier) carefully observing polarity.

10.Turn on the receiver or amplifier and test all loudspeakers in the system.

PAINTING THE GRILLE AND FRAME

The CM850Si loudspeaker and flush-mount metal grille may be painted without the need for primer.

1.Install loudspeaker into ceiling or wall following the previous steps 1 - 6.

2.Remove the smallest perforated circle from the cardboard square template. This is the paint mask that protects the loudspeaker from paint. Gently press it into place inside the baffle.

3.Paint the frame of the loudspeaker.

4.Paint the grille separately from the loudspeaker frame. For best results when painting the grille, use a spray gun or airless sprayer. Thin the paint to prevent clogging of the grille holes and apply several light coats instead of one heavy one.

5.Gently remove the paint mask after paint has dried by pressing in the tab in the center and carefully pulling out the mask with your finger. Be very careful not to poke the tweeter with your finger.

6.Finish installation of the loudspeaker following the previous steps 7 –10.
