IMPORTANT: WHEN INSTALLING THE LOUDSPEAKERS 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 screwdriver
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 loudspeakers in the system
according to the receiver manufacturer’s instructions.
CHECKING LOUDSPEAKER PHASE
Loudspeaker wire has two conductors. On both your loudspeaker 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
