FIRST THINGS FIRST
Caution: Subwoofers are heavy. Exercise caution when unpacking your subwoofer.
Please inspect your loudspeaker carefully. Notify your Polk dealer if you notice
any damage or missing items. Keep the carton and packing material. It will
do the best job of protecting your speaker if it needs to be transported.
Your system includes a detachable power cord that’s packaged separately from
the cabinet. Insert female end into the receptacle on the amplifier plate and insert
the polarized AC plug into a wall outlet (or power strip) as per the safety instructions
found on the inside cover of this manual. We do not recommend connecting the
subwoofer’s AC power cord to your receiver’s switched outlet.
PLACING YOUR SUBWOOFER IN A ROOM
Your PSW Series subwoofer is not magnetically shielded. Do not place near video moni-
tors. (LCD, DLP and Plasma televisions are not affected by magnetism.) Allow at least
18" (45cm) of space between your subwoofer and any television, but if you do notice
video distortion or discoloration, immediately move the subwoofer away from the TV.
Your PSW Series subwoofer offers many placement options: in an entertainment center,
behind furniture, or next to a sofa or chair. You may place your subwoofer anywhere in
the room, but you'll enjoy the best performance when it’s on the same side of the room
as your system's front speakers (Figure 1). Placing your subwoofer near a wall or in
a corner will increase its loudness. When placing your subwoofer in the room, always
place your subwoofer on its base feet side down (Figure 2). If you can at all avoid it,
do not place your subwoofer next to an open door.
We do recommend placing your subwoofer in different locations within your room
to learn what produces the best sound quality for your listening environment. For
more information on subwoofer placement, go to www.polkaudio.com/education/

OPTION #1—
Receivers that include a “Sub Out” feature—the most common hookup method
with Dolby
® Digital receivers.
• Connect a single RCA cable from the “SUB OUT” of your receiver to the LFE input of
the subwoofer. This connecting method bypasses the subwoofer’s internal filter and
relies on the filter built into your receiver. Make no other signal connections.
Do not use speaker wire to make the connection to the subwoofer.
• Connect all speakers directly to the receiver. When using method #1, adjust
your receiver’s speaker configurations as follows: Set Front, Center and Surround
speakers to “small.”
• Depending on your speakers’ bass output capabilities, set the crossover frequency
on the receiver to 80Hz for tower and bookshelf speakers (speakers with a woofer
5 1/4" in diameter or larger) and 100-120Hz for satellite speakers.
Receiver Settings:
• Front, Center, and Surrounds = “SMALL”
• Subwoofer = “ON,” or “YES,” or “PRESENT”
Consult your receiver’s owner’s manual for speaker configuration.
