Niles Audio CM5PR Speaker User Manual


 
Recommended Amplifier Power
For satisfactory performance, we recom-
mend an amplifier with a power rating of
10 to 100 watts for the CM5PR and 10 to
125 watts for the CM6PR. Curiously, most
speakers are not damaged by large ampli-
fiers but by small amplifiers. If your system
is playing loudly, a small amplifier will
run out of power very quickly. When an
amplifier runs out of power it creates dam-
aging “clipping” distortion. A large ampli-
fier will play at the same volume without
distorting. 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.
