CONNECTING AND INSTALLING THE SPEAKER (CONTINUED)

IMPORTANT: WHEN INSTALLING THE SPEAKERS IN THE CEILING, OR IF THE INSTALLATION IS IN AN EARTHQUAKE ZONE, WE RECOMMEND USING THE ENCLOSED SHEET METAL SCREWS TO SECURE THE BAFFLE TO THE FRAME AS FOLLOWS:

a.Locate the dimples on the front baffle.

b.Place the self-tapping sheet-metal screw in the dimple and turn it with a screw- driver until it cuts through the baffle and anchors securely in the frame, as shown in Figure 17.

5.Turn on the home theater receiver and calibrate all speakers in the system according to the receiver manufacturer’s instructions.

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 the 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 that 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 playing together will be lacking in bass and sound “phasey.” If you suspect the sound is not right, and you cannot see any markings on the wire, try this simple test:
