POLK AUDIO—
A HISTORY OF EXCELLENCE
Polk Audio was founded in 1972 by Matthew
Polk and George Klopfer. Their dream was to
make speakers with the performance of the
world’s best speakers, at reasonable prices.
They did so by applying scientific principles
to speaker design and by concentrating solely on the speaker business. That is how Polk
became known as “The Speaker Specialists®.”
Today Polk Audio is still headquartered in
Baltimore, Maryland and is now one of the
world’s largest manufacturers of home and
car loudspeakers. Polk’s research has yielded
over 20 patents for advances in loudspeaker
performance and value. Polk speakers have
earned the praise of audio experts the world
over, as well as dozens of awards for innovative, high-quality design. Polk Audio speakers
are sold in over 50 countries and in audio/
video specialist retail locations throughout
the U.S.
Founders Matthew Polk and George Klopfer
still work alongside 300 dedicated Polk team
members to bring you the best speakers you
can buy.
FEATURES:
• 8"(PSW250), 10"(PSW350) or
12" (PSW450) direct radiating
subwoofer driver for deep bass,
smooth response and low distortion.
• Dual bass ports for deep bass and high
acoustic efficiency.
• High current 50 watt (PSW250),
100 watt (PSW350) or
150 watt (PSW350) power amplifier
• Subwoofer volume control, variable
crossover control and phase switch allow
you to optimize performance to match
your audio system, room acoustics, and
program material.
•LFE input (PSW350 & PSW450)
• Switchable 80Hz high pass or full range
speaker outputs (PSW450)
• Auto on-off circuit that automatically
turns your subwoofer on when it senses
a program signal. When no signal is present, the circuit mutes the subwoofer.
GETTING STARTED
Please inspect each loudspeaker carefully.
Notify your Polk dealer if you notice any damage or missing items. Keep the carton and
packing material. They will do the best job of
protecting your speakers if they need to be
transported.

SPEAKER PLACEMENT
Due to their compact size, Polk PSW Series
subwoofers offer plenty of placement
options—in an entertainment center, behind
furniture or next to a sofa or chair. The subwoofer may be placed anywhere in the room,
but for the greatest possible bass output,
place the subwoofer in a corner of the room.
The subwoofer may lay on its side, but placing it on its feet or base will yield the best
performance (Figure 1). NEVER LAY THE
SUBWOOFER ON THE AMPLIFIER END—
THIS WILL DAMAGE THE AMPLIFIER.
The PSW250, PSW350 AND PSW450 are
magnetically shielded and can be placed
close to a television set, if necessary.
However, we do not recommend placing your
TV set on the subwoofer. The vibration
transmitted to the TV set may shorten the
life of the TV. If you see any color distortion
in your TV, move the subwoofer a few inches
further from the set.

CONNECTING THE SPEAKERS
TO THE SYSTEM—GENERAL
If you elect to use the speaker level inputs,
use two conductor 16 gauge or thicker speaker wires. If you choose to use the line level
inputs, use high quality, shielded RCA type
interconnect cables (see hookup options). See
your Polk dealer for wire recommendations.
Note that one of the terminals on the rear of
the speaker is marked red (+) and the other
black (-). Make certain that you connect the
wire from the red (+) terminal of your amplifier to the red (+) terminal on your speaker,
and the wire from the black (-) terminal of
the amplifier to the black (-) terminal on your
speaker. Most wire has some indication (such
as color coding, ribbing, or writing) on one
of the two conductors to help maintain consistency. If your speakers sound “thin” with
little bass and little to no center image, odds
are that one of the speaker wires is connected backwards. Double check all connections.

Strip 1/2" of insulation from each of the two
conductors on both ends to expose the bare
wire. Twist the exposed wire of each conductor
to form two unfrayed strands. Connect two
conductors to the receiver or amp (refer to the
owner’s manual supplied with your electronics
for assistance with proper hookup). Connect
the two conductors on the other end of the
wire to the speaker terminals.

USING PUSH-TAB AND 5-WAY
BINDING POST CONNECTORS
Push the plastic tab of one connector to open
up the hole. Insert the bare wire into the hole,
and release the plastic tab. Repeat this step
for the other terminal (Figure 2).
The PSW450 uses 5-way binding posts, which
operate a little differently. Unscrew the red or
black nut several turns until the hole in the
shaft appears. Push the bare wire into the hole
and retighten nut finger tight (Figure 2a).
Make sure that the two bare wire ends do not
touch each other. Such an electrical short will
cause your receiver or amplifier to turn off or
malfunction.
