Niles CM8SW Installation & Operation Manual page 4

Infinite Baffle Design
The CM8SW is designed for optimum low
frequency reproduction in traditional ceil-
ing environments and varying air volumes.
It does not require a special enclosure to
provide high performance.
Selectable High-Pass Filter
Installers can also select whether or not to
filter the low frequencies from the satellite
speakers at a fixed frequency of 120Hz.
Like the low-pass filter, this selection is
accessed via baffle mounted controls
(See Figure 2).
Adjustable Low Pass Filter
Installers can select passive crossover for
both woofer and satellite speakers via
baffle-mounted controls that are
accessible even after the subwoofer has
been installed (See Figure 3).
Weather-Resistant Construction
All components of the CM8SW are weath-
er resistant. The aluminum grille and stain-
less steel mounting screws are rustproof.
This makes the subwoofer ideal for moist
environments which would cause some
brands of speakers to discolor. Protected
outdoor installations are perfectly suited
for the CM8SW.
MicroPerf
The CM8SW employs Niles' exclusive
MicroPerf grille construction. The excep-
tionally tight hole pattern provides
acoustic transparency at all audio frequen-
cies and enables the woofer element to
remain invisible. MicroPerf grilles can be
painted to blend seamlessly with the
surrounding decor.
No-Strip Speaker Wire Terminals
Dual Niles patented gold-plated no-strip
speaker wire terminal connectors accom-
modates 12-18 gauge wire.

Easy Installation
The CM8SW employs a bracketless
mounting system for existing ceilings.
Simply cut a hole in the mounting surface,
remove the grille from the subwoofer,
connect the wires and place the speaker
in the hole. Then tighten the four mount-
ing "dogs" via the front panel screws. The
dogs first swivel 90°, then clamp the frame
to the drywall as the screws are tightened.
Hole Saving Bracket
Available as an optional accessory, the
CM8 New Construction Bracket can be
installed as a "hole-saver" before the dry-
wall goes up. The drywall contractor cuts
the hole as the drywall is installed, reduc-
ing installation time and minimizing the
chances for lost wires.
