INSTALLING THE SPEAKERS (CONTINUED)

6.At each speaker, set the DIFFUSE/DIRECT switch according to the desired application (see page 8 for usage).

7.At each speaker, set the TWEETER LEVEL switch according to the desired application (see page 9 for usage).

8.Install grilles into each speaker – they should fit snugly. If they don’t, try loosening the mounting-dog screws. They may have been tightened too much.

PAINTING THE SPEAKERS

The CM6HDfx speakers may be painted, as the plastic frame will readily accept most paints. For best results, 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.

1.Paint the grilles first and let them dry before installation.

2.Mask all speakers prior to painting them. You can use the inside circular portion of the hole template as a paint mask.

3.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 double-sided loop. Affix the tape to the tweeter and place the mask onto the speaker.

4.Paint the speakers. After they are dry, install the grilles.

CHECKING SPEAKER PHASE

Speaker wire has two conductors. On both your speaker and amplifier, one conductor is attached to the negative (–) terminals, while the other is attached to the positive (+) terminals. Usually, the wire is marked for your convenience, but the marking can be done in following different ways:

Stripe on one wire

Ribbed area you can feel on one conductor

Different colors of metal wire on each conductor

Fabric strand or string wound into one of the conductors

Of course, there are some wires which appear completely identical. So be careful, or you might make a connection mistake. If you do, one speaker will be playing “out-of-phase” with the other speaker. A pair of out-of-phase speakers works against each other, and the sound of the two
