Please inspect your subwoofer carefully. Notify your Polk Audio dealer if you notice any damage or missing items. Keep the carton and packing material. It will do the best job of protecting your subwoofer if it needs to be transported.

Your system includes a detachable power cord that’s packaged separately from
the subwoofer. Insert the female end into the receptacle on the amplifier plate and insert the 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.


While your wireless-ready subwoofer may be placed anywhere in the room, it is
magnetically shielded for placement near video monitors. (LCD, DLP and Plasma
televisions are not affected by magnetism.) Allow at least 18″ (46cm) of space
between your subwoofer and any tube television, but if you do notice video
distortion or discoloration, immediately move the subwoofer away from the TV.

Also, the Polk Room Optimizer (PRO™) feature lets you place your subwoofer anywhere in the room without compromising performance. When locating your subwoofer in the room, we recomment placing it on its base, feet side down.
If you can 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 based upon your listening preferences.

The PRO feature will tailor your subwoofer’s performance to its location in your
room. Select one of the four buttons on your subwoofer’s remote control that
indicates where you’ve placed your subwoofer in the room. (For more on this
feature, see “Polk Room Optimizer.“)

For more information on subwoofer placement, go to

Feet/Carpet Spikes

Wireless-ready subwoofers have removable feet. Each foot’s shaft is also a
carpet spike, which allows you to place your subwoofer on a carpeted floor.

To remove the conical feet from the carpet spike, grasp a foot firmly and turn
the foot clockwise while pulling up. Three complete turns should raise the foot
enough to allow you to place your fingertips under the foot and pull it off the spike.


Your wireless-ready subwoofer can be placed in a cabinet, thereby
reorienting the subwoofer’s driver so that it faces into your listening room.
See the instructions below:

Note: The remote control may not operate when the subwoofer is placed
in a cabinet with the driver facing into the room. If this occurs, adding an IR
repeater will enable the remote control to communicate with the subwoofer.

Instructions For Placing Subwoofer In Cabinet:

  1. With the subwoofer’s logo facing you, turn the sub on its side.
  2. Unscrew the feet from the bottom of the subwoofer.
  3. Reattach the feet in the threaded inserts located
    on the amplifier side. Press rubber inserts into bottom of feet.
  4. Turn the subwoofer onto its feet. Place the subwoofer in the cabinet
    so that the driver faces into the room.

Note: Grilles are available for wireless-ready subwoofers at your authorized Polk Audio dealer or at www.polkaudio.com.

Dual Voltage Switch

Wireless-ready subwoofers are equipped with either a dual voltage switch or an auto sensor.

DSWPRO660WI Selectable

WARNING: The correct voltage for your country has been set at the factory. Only use the voltage setting specified for your country. Using an improper setting may damage your subwoofer. Main Power Switch Turn power on/off via the AC MAIN switch.

Standby/Auto/On Switch

Your wireless-ready subwoofer uses a 3-position power switch, which selects
your subwoofer’s operational mode. The three modes are: Standby, Auto and On.


With the switch in this position, the subwoofer will only turn on (become active)
when the user presses the power button on the remote control. Once active the
subwoofer will remain on regardless of whether an audio signal is present.


Note: Wired connections only.
In the “Auto” position, your subwoofer automatically turns on when it senses
an audio signal and the LED located on the back of the subwoofer will be green.
When no signal is present, the subwoofer will enter a “waiting” state after 10
minutes and the LED will turn yellow.
We recommend the “Auto” mode if your subwoofer is always receiving
power (i.e., if it’s plugged into a wall outlet).

The subwoofer is always on and fully active in this mode. The LED on the back of
the subwoofer will be green. This mode is best if the subwoofer is plugged into a
switched power outlet. The remote control cannot be used to turn off the subwoofer.
Note: You may want to leave your subwoofer unplugged or the AC MAIN
switch turned off during extended periods of non use, such as during a vacation
and also during electrical storms.

Power Mode LED Colors And Their Meaning:

Green: Fully active
Yellow: Standby
Red: Protection



Wireless Connections

Verify that on your receiver you have a dedicated subwoofer output jack,
(common on most Dolby Digital 5.1, 6.1 and 7.1 surround receivers). The
output will be labeled “SW Out,” “Sub-Pre Out” or something similar. Using a
single subwoofer cable, connect the receiver to the LFE input on the transmitter
as shown in the OPTION #1 illustration.

OPTION #2 Line Level
If your receiver does not have a dedicated subwoofer output jack (common with
stereo (2 channel) and older Dolby Pro-Logic receivers), use line level connections. Connect the preamp outputs of your receiver and to the LEFT and RIGHT inputs on the transmitter as shown in the OPTION #2 illustration.

Wired Connections

OPTION #1 Receivers that include a “SUB OUT” feature—
the most common hookup method with Dolby Digital
® and DTS® receivers.

  • Connect a single RCA cable from the “SUB OUT” of your receiver to the LFE/R input of the subwoofer. This connection 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 other speakers directly to the receiver. Adjust your receiver’s speaker configurations as follows:
  • Front Speakers = SMALL
  • Center and Surrounds = SMALL
  • Subwoofer = ON, YES, or PRESENT
  • Depending on your front 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. Consult your receiver’s owner’s manual for instructions.

OPTION #2 Two channel or Dolby Pro Logic® receiver with no “SUB OUT.”
Use two-conductor 16 gauge or thicker speaker wires. See your Polk Audio
dealer for wire recommendations.

Note: Do not use the line or LFE input in this configuration.

  • Connect the left and right front speaker outputs of your receiver to the speaker level inputs of the subwoofer using speaker wire (see “Making Binding Post/Speaker Wire Connections” for detailed instructions).
  • Connect the left and right front speakers using speaker wire from the speaker level outputs from the subwoofer.
  • Connect the center channel speaker directly to the center channel output from your receiver.
  • Connect the rear surround satellites directly to the rear or surround channel outputs from your receiver.
  • Adjust your receiver’s speaker configurations as follows:
  • Front Speakers = LARGE
  • Subwoofer = OFF or NO
  • Center and Surrounds = SMALL

OPTION #3 Receivers with full-range (unfiltered) Left and Right “Pre Out”
jacks (this is the least commonly used hookup).

  • Connect the left and right preamp outputs from your receiver to the left and right LINE LEVEL inputs of the subwoofer. Do not use speaker wires.
  • Connect the left and right LINE LEVEL outputs to the left and right inputs on the power amplifier.
  • Adjust the settings on your receiver as follows:
  • Front Speakers = LARGE
  • Subwoofer = OFF or NO

Making Binding Post/Speaker Wire Connections

Note that one of the speaker input terminals on the rear of the subwoofer is
marked red (+) and the other black (-). Make certain that you connect the wire
from the red (+) terminal of your receiver to the red (+) terminal on your subwoofer and the wire from the black (-) terminal of the receiver to the black (-) terminal on your subwoofer. Speaker wire has some indication (such as color coding, ribbing, or writing) on one of the two conductors to help maintain consistency.

Note: If your subwoofer doesn’t seem to produce much bass, it is most likely
that one of the speaker wires is connected backwards. Double check all
connections for correct polarity.

Strip 1/2″ (12mm) 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
un-frayed strands (one on each end).

Unscrew the binding post hex nuts several turns. Insert the exposed wire,
ensuring that none of the bare wire ends touch each other, because contact
could result in an electrical short and cause your receiver to turn off or malfunction. With the speaker wire inserted into the binding post, turn the hex nut clockwise until it’s snug.


Note: When you set up your subwoofer for the first time, you will probably have
to make adjustments several times before you hear what you personally like.
Don’t forget to turn the AC MAIN power switch on.


Your wireless-ready subwoofer offers a range of settings. The unit’s
initial settings are as follows:
• Phase: 0
• Volume: 50% (20, on a scale from 0-40)
• PROsetting: mid-room

The settings that are best for you depend upon your subwoofer placement,
electronics and personal taste. After you’ve become familiar with what the
settings do, experiment with alternate options to find the method that
works best for your system setup. You’ll find an informative article on
“Subwoofer Positioning and Adjustment” in the set up section at:


Where you place your subwoofer in your room affects its response. wireless-ready subwoofers incorporate the Polk Room Optimizer (PRO) feature—four pushbutton room equalization presets that maximize your subwoofer’s performance for typical room placements: “cabinet,” “corner,” “mid-wall” and “mid-room.”

A traditional subwoofer’s response is affected by its location in a room. The
Polk Room Optimizer (PRO) feature allows you to place your wireless-ready
subwoofer where you want it in your listening room. Based upon the four most
common room placements for subwoofers, PRO maximizes sound quality for you, smoothing out the bass response that a particular room placement creates. You simply choose the location you want and select the corresponding button on your subwoofer’s remote control.


  • Volume: Adjust by ear using a wide variety of CDs and video sources. Adjust for deep, powerful bass without “boominess.”
  • Low Pass Filter Control: NOTE: This control does not operate when the subwoofer is connected with Option #1 (wireless/wired LFE Input). This control, which is located on the back of the amplifier, adjusts the frequency range over which the subwoofer operates. When using smaller main speakers the upper
  • range of the control will probably yield the best results. With larger speakers the lower end of the control range will probably sound best, but always let your ear be the final judge. If male vocals sound “thin,” turn this control up until the voice sounds rich but not “boomy.” If male vocals sound too “thick” or “chesty,” turn this control down until the voice sounds natural.
  • 4 Button Phase Control (0, 90, 180 and 270 degree settings): This control enables the subwoofer to blend more seamlessly with your main speakers. Sit in your favorite listening position. Using the subwoofer’s remote control, play music (not a movie) with a walking bass line. We recommend playing jazz or country music. Now listen carefully for the point at which the subwoofer transitions to your main speakers. This is the crossover point, and this point should be below the frequency of a male human voice. Whichever phase setting sounds louder or fuller at the subwoofer’s crossover (transition) point is the optimum setting. If after trying all four possible phase settings you cannot hear any difference, leave the phase setting at “0.

Wreless ready subwoofers come with a credit card sized remote control. All commands are sent to the subwoofer via IR control. The IR receiver is located on the front of the subwoofer when the subwoofer is in its downward firing configuration.

The remote control has the following features:

  • Power
  • Volume
  • 4 Button Phase Control (0, 90, 180 and 270 degree settings)
  • 4 Button Polk Room Optimizer (PRO) presets
  • Mute function
  • Night function allows you to hear low-level bass detail at lower volumes. If you have the volume at 30 and press “night,“ the volume is reduced by 50%, in this example to 15. Pressing “night“ a second time restores the volume to its original setting. Pressing Volume+ (or Volume-) incrementally increases (or decreases) the volume in the normal manner and takes the subwoofer out of “night“ mode. Also, the LED shines at a reduced intensity when the subwoofer is in “night“ mode.
  • Reset button restores the woofer’s settings to factory presets. Hold down for two (2) seconds.
  • LED turns LED On/Off. The amplifier remains active.

Important: To activate the remote control for the first time, remove the plastic tab.

Behind the logo badge on the front of your subwoofer there is a blue LED. The blue light blinks whenever you press a button on the subwoofer’s remote control. The light lets you know that the subwoofer has received the command and is enabling the function you’ve selected. The following table describes each button’s function and how the LED communicates to you:

Power LED is on when power is active and is off when power is not active. (Pressing the LED button on the remote will also turn the LED off.)

Volume LED will blink a 2-digit code indicating volume setting from 0 to 40 (i.e., if the volume is turned up to 28, the LED will flash two long blinks followed by eight short blinks).

Mute LED blinks slowly when “mute” is selected. Phase 0 degrees—1 blink; 90 degrees—2 blinks; 180 degrees—3 blinks; 270 degrees—4 blinks.

Night LED is on at a lower intensity; volume is reduced by 50%. PRO Presets Cabinet—1 blink; Corner—2 blinks; Mid-wall—3 blinks; Mid-room—4 blinks.

Reset LED will blink 4 times. LED Turns LED on/off. The amplifier remains active.

  • No sound coming from subwoofer – If hookup is “SUB OUT” to LFE, check and make sure your receiver is set to Subwoofer = YES. If hookup is via speaker wire, check that the polarity of the wires is correct.
  • Subwoofer doesn’t sound right. – Adjust volume, low pass filter, phase and PRO settings.
  • The subwoofer is humming. – There could be interference from a cable TV line. Disconnect the cable TV line from the cable box to see if the hum stops. A low-level hum is normal.
  • Subwoofer has no power – Is the AC MAIN switch on? Check outlet; check fuse after unplugging the subwoofer. The fuse is located under the power cord receptacle. Fuse type and rating is found on the back panel.
  • Remote control doesn’t work – Remove the plastic tab to activate the remote control’s battery or try replacing the battery. Ensure the IR sensor is not blocked.
  • Power LED is red. – Unplug subwoofer for 15 minutes, then plug back in.
  • The subwoofer’s sound is intermittent, sounds weak or is distorted. – – Turn off both the the transmitter and the wireless subwoofer. Then turn them back on to re-establish communication. Try changing settings of the Channel ID switches on both the transmitter and the wireless subwoofer. The wireless subwoofer could be too far away from the transmitter to receive a sufficiently strong signal. Try moving it closer

A Note Regarding Wireless Performance:

Like all wireless devices, your DSWPROWI may be susceptible to RF interference from such sources as microwave ovens, WiFi computer systems, video game systems, cordless telephones, blue tooth systems, baby monitors and other
devices. In particular, any devices operating in the 2.4GHz band may cause intermittent wireless connections between the DSWPROWI. It is also possible that your DSWPROWI may affect other wireless systems. For the most part, you can avoid wireless performance problems by physically separating these
devices from your DSWPROWI. Maintaining a distance of several feet or more between your DSWPROWI speaker and any wireless device should prevent any mutual interference effects. If you do notice any subwoofer signal dropouts take care to identify the root cause (most commonly having other wireless
devices too close) and resolve accordingly. Any interference effects from a microwave oven will cease once the oven stops operating and may be resolved on a long-term basis by increasing the physical distance between your DSWPROWI and the microwave oven.
