Niles Audio CM8MP - Manual (Page 3)

Easy Installation
The MP Multipurpose series speakers
employ a bracketless mounting system in
existing ceilings. Simply cut a hole in the
mounting surface, remove the grille from
the speaker, connect the wires and place
the speaker in the hole. Then tighten the
four mounting “dogs” via the front panel
screws. The dogs first swivel 90°, then
clamp the speaker frame to the drywall as
you tighten the screws.
Hole Saving Bracket
Available as an optional accessory, CM5
Series, CM6 and CM8 Series New
Construction Brackets can be installed as a
“hole-saver” before the drywall goes up.
The drywall contractor cuts the holes as
the drywall is installed, reducing installa-
tion time and minimizing the chance for
lost wires.
Installer Selectable Acoustic
Fine Tuning (CM8MP Only)
Installers can select to de-emphasize the
bass or treble by 2dB to accommodate
reflective surfaces and corner loading.
This selection is accomplished via baffle-
mounted controls that are accessible after
the speaker has been installed.

Recommended Amplifier Power
For satisfactory performance, we recom-
mend an amplifier with a power rating of
five to 60 watts for the CM5MP, five to 75
watts for the CM6MP and five to 100
watts for the CM8MP. 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.

The MP Multipurpose tweeter is
housed in a custom designed, low
diffraction enclosure which pivots
up to 20° to provide optimum high
frequency coverage
