Recommended Amplifier Power
For satisfactory performance, we recom-
mend an amplifier with a power rating of
10 to 100 watts for the CM5AT; 10 to 125
watts for the CM6AT and 10 to 150 watts
for the CM8AT. Curiously, most speakers
are not damaged by large amplifiers but
by small amplifiers. If your system is play-
ing loudly, a small amplifier will run out
of power very quickly. When an amplifier
runs out of power it creates damaging
“clipping” distortion. A large amplifier will
play at the same volume without distort-
ing. See the section on operating the
speakers for more information about clip-
ping distortion.

Installation Considerations
New Construction Bracket serves as a
“hole saver” when drywall has not
been applied. It is not necessary when
retrofitting to existing ceilings.
Knockout wire tie allows the wire to be
secured to the bracket throughout the
new construction process. It knocks
out cleanly when the speaker is
installed.
New construction wings
instantly snap into the
bracket without screws.
Wings are scored for
easy size trimming.
Brackets and wings
attach to the ceiling joists
with nails or screws.
Dogs swivel 90°, then
clamp the speaker
frame to the drywall.
Frames are molded with a
slight texture to assure
good paint adhesion.
Mounting screws tighten the
“dogs”, clamping the speaker
to the drywall.
Rust-proof aluminum grilles make the CM
series perfect for moist environments.
