5) Place the speaker into the rough opening.
6) Level the speaker and tighten the screws, being careful not to over tighten them. See
diagram below for details.

Note: The AMC 900
THX
is sold in pairs. On the cabinet, near the input terminals, is a temporary
label to specify screen direction. The response will be slightly superior in this direction. Install
the two AMC 900
THX
’s so that the arrows BOTH point toward the screen. If listeners are not
going to be located on or near the center axis of the speaker, the speaker should be oriented
with the arrow toward the listener location (even if this is away from the screen).
LISTENING LEVELS AND POWER HANDLING
The power recommendation for the system assumes you will operate the amplifier in a way that
will not produce distortion. All speakers can be damaged by even a modest amplifier if it is
producing distortion. If you hear a gritty noise or other signs of strain, turn down the volume.
Prolonged or repeated operation of your speakers with a distorted signal can cause damage
that is not covered by the warranty. It is especially important that you do not overdrive the
bass capability of smaller speakers. Watch for noises, such as pops, caused by the music’s bass
line. Use of the loudness control and/or full bass boost at louder volumes is likely to overdrive
the woofer. Use such controls sparingly.
HOW TO CARE FOR YOUR SPEAKERS
Use a soft terry cloth towel slightly dampened with water, glass cleaner, or a diluted mild
detergent. The towel should be just damp enough to wipe the surface clean without leaving
a trail of moisture.
Do not use abrasive cleaners or any cleaner containing chemicals harsher than those found
in glass cleaner.
Turn the mounting
clamps against the

place the speaker

head screwdriver
to deploy the
mounting clamps
and pull them
against the back
of the drywall.
