There should be no gaps between the wall and the frame. IMPORTANT: DO NOT OVER TIGHTEN THE SCREWS! OVER TIGHTENING THEM MAY MAKE THE GRILLE DIFFICULT TO INSTALL 7. Direct the tweeter. (CM730, CM750 & CM760 only) 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. (CM760 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. PAINTING THE GRILLE AND FRAME Each CM710, CM730, CM750 & CM760 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. • Cordless drill with 1/4 – and 1/2- inch drill bits and a 1-inch paddle drill bit (for drilling through studs) • Stiff wire, fish tape or glow rods for routing cables • Rubber gloves and protective eyewear • Keyhole or drywall saw • Phillips screwdriver set • Wire stripper • Stud finder • Cable ties • Pencil • Turn off all system power before making any connections • Always wear protective eyewear when using tools • Make sure hands are clean before installation • Wear gloves when working with fiberglass insulation Figure 2.
