12-INCH WOOFER WITH CARBON-FIBER-IMPREGNATED
PAPER CONE AND BUTYL-RUBBER SURROUND
The SW300 features a 12-inch long-throw, front-firing woofer with a Carbon-Fiber-Impregnated
Paper Cone combined with a Butyl-Rubber Surround for maximum bass response with reduced
sonic breakup and lower distortion.
SOPHISTICATED MOTOR ASSEMBLY WITH HIGH BL
MAGNET, EXTENDED POLE PIECE, AND CAST
ALUMINUM DRIVER BASKET/FRAME
The SW300’s woofer features a sophisticated motor assembly that combines a high BL magnet
and extended pole piece for deep bass response and clean bass tones. Moreover, the cast
aluminum driver basket/frame provides extra rigidity to the entire assembly for consistent
performance over prolonged use.
ADVANCED DIGITAL AMPLIFIER CREATES AMPLE POWER
WITH LITTLE HEAT
Powered by an internal 300-watt (rms) advanced digital amplifier, the SW300 can easily
reproduce 600-watt peaks with very little heat produced. Niles uses the latest digital technology
so bass response will be extremely fast and absolutely accurate, no matter what audio material is
being reproduced.
SEPARATE SUBWOOFER LEVEL CONTROLS AND
TRIGGER INPUT FOR MOVIES OR MUSIC
Separate subwoofer level controls for music and movies provide the right bass levels for different
types of programs. When activated by 12 volts input, the SW300’s MOVIE MODE trigger input will
automatically adjust the bass level appropriate for the source material.
RCA LINE-LEVEL AND LOUDSPEAKER-LEVEL INPUTS
In addition to gold-plated RCA line-level inputs, the SW300 features a gold-plated, non-filtered RCA
LFE (Low Frequency Effects) line-level input for a direct connection from a 5.1 or 7.1 home theater
sound processor. Using the “LFE” input bypasses the “Low Pass” frequency control.
The SW300 also has gold-plated, loudspeaker-level, five-way binding-post input connections.
Using this input allows control over the “Low Pass” frequency output of the SW300.

ADJUSTABLE LOW-PASS, HIGH-PASS,
AND PHASE CONTROLS
Variable low-pass and high-pass filters divide the incoming stereo audio spectrum into separate
signal paths for the mono subwoofer reproduction and stereo pass-through to a pair of satellite
loudspeakers. A fully-adjustable (0-to-180 degree) phase control ensures optimal system
integration, no matter where the SW300 is placed in the room.
INSTALLATION CONSIDERATIONS
RCA CABLE
For the best possible performance using the line-level connections, use high-quality RCA cables
that feature low impedance and gold-plated connectors. Consult your local Niles dealer for
their recommendations.
MUSIC SENSE CIRCUITRY FOR AUTOMATIC
POWER ON/OFF
When activated, the SW300’s music sense circuits will continually monitor the audio inputs and
automatically power on the subwoofer when audio signals are detected. Conversely, the music
sense circuits will automatically power off the subwoofer, after a preset time, when signals are no
longer present. The SW300 also includes a POWER TRIGGER input that allows a 12 volt input to
remotely power on/off the SW300 in the same way.
CASCADE AUDIO OUTPUTS FACILITATE EASY
CONNECTION OF ADDITIONAL WOOFERS
For larger rooms, or stereo subwoofer applications, several SW300’s can be easily added to a
home theater system using the cascading line-level audio outputs to feed additional SW300 audio
inputs in a daisy-chain connection.
ATTRACTIVE, YET RIGID, COMPACT CABINET WITH
REMOVABLE METAL GRILLE
The SW300 is housed in an attractive, compact, 11-layer no-void, birch-ply, cross-braced black
cabinet that provides the ultimate in rigidity and sound clarity. The black perforated-metal grill is
removable for those interested in showcasing the technology.
ADJUSTABLE ISOLATING FEET
LOUDSPEAKER WIRE
Use 2-conductor loudspeaker wire when connecting loudspeakers to your receiver or amplifier.
For most applications, we recommend using 16- or 18-gauge wire. For wiring runs longer than 80
feet, we recommend 14-gauge wire. The binding post terminals will accommodate up to 12-gauge
wire directly. Larger sizes can be accommodated via pin connectors.
When running wire inside walls or ceilings, always use (CL-2 or CL-3) rated cable. In some areas,
conduit is also required. For a trouble-free installation, low-voltage wire such as speaker wire
must be run in accordance with the National Electrical Code and any applicable provisions of the
local building code. If you are unsure of the correct installation techniques, wire jacket, or type of
conduit to use, consult a professional audio/video installer, building contractor, or the local building
and inspection department.
TECH TIP
Wire size is expressed by its AWG (American
Wire Gauge) number – the lower the number,
the larger the wire. For example, 12 AWG is
physically larger than 14 AWG.
NOTE: THE NILES SW300 POWERED SUBWOOFER IS EXPRESSLY DESIGNED FOR USE IN HOME THEATER
AND MUSIC APPLICATIONS. FOR HOME THEATER FRONT- OR CENTER-CHANNEL APPLICATIONS,
WE RECOMMEND USING A NILES PHD, HDLCR, OR HDLCRBX LOUDSPEAKER. FOR REAR-CHANNEL
APPLICATIONS, WE RECOMMEND USING A NILES HDFX, CM6HDFX, OR DS LOUDSPEAKER.
The SW300 is equipped with four adjustable spike feet (pre-installed with large slip-on rubber
covers) that mechanically couple the woofer cabinet to a hard floor. For carpet placement, the
rubber covers can be removed to reveal the spikes.
DOLBY® DIGITAL READY
The SW300 is specifically designed for Home Theater Sound. This model exceeds the specifications
set forth by Dolby Laboratories for the accurate reproduction of Dolby Digital-Encoded Sources.
