Painting the Grille and Frame

7.Direct the tweeter. The tweeter is directed by gently pressing on the outer edge of the tweeter housing. It will move up to 20 degrees in any direction. For critical listening, direct the tweeter towards the user’s favorite listening position. For surround sound or low volume background listening, create more reﬂections and thus more ambiance by directing the tweeter towards the sidewalls. (See Figure 4)

8.Set the Treble level control. (CM860 only) Listen to a well-recorded piece of music at the user’s favorite listening position. Listen for treble harshness or ringing, particularly when the loudspeakers are placed in a room without carpet. Use the -3dB Treble cut position to correct. Listen for dull or mufﬂed upper frequencies, particularly when the loudspeakers are installed in an area with thick carpet or fabric wall coverings. Use the +3dB Treble boost position to correct. (See Figure 5)

9.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.

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

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

Each CM830, CM850 & CM860 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 - 7.

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 8 –10.
