22. This product is not intended for use outdoors.
Safe Limits of Operation
Polk specifies the recommended amplification range for each of its passive (non-amplified) loudspeakers. Typically that specification will be expressed as a range of power such as 20-200 Watts (per channel). It is important to understand what those numbers mean when choosing a receiver or amplifier for your Polk loudspeakers. The lower number indicates the lowest continuous rated power that will yield acceptable performance in a typical listening environment. The higher number indicates the highest per channel power that should be used with your Polk speakers. That number should not be confused with a “Power Handling” specification, and it does not imply that the speaker will safely handle that full amount of power on a long-term basis. We specify a wide range of power ratings because not all electronics manufacturers use the same method for rating power. In fact, high quality lower-rated amplifiers sound better and play louder than low quality units with higher power rating.
Similarly, we recommend using amplifiers and receivers with rated power above the Power Handling limits of our speakers because having extra power available for short term peaks is conducive to better sound quality, maximum dynamic range and effortless high volume output. But we strongly urge you not to use the full power of your amplifier or receiver for daily listening.
Loudspeakers can be damaged when an amplifier, regardless of its wattage, is made to play at higher listening levels than its power can clearly produce. Operation at this level can result in very high levels of audible distortion originating in the amplifier, which can add a harsh, gritty sound to your listening material. If you hear distortion—turn the volume down or risk damaging your speakers. You can damage just about any speaker, regardless of power rating, if you drive an amplifier to or beyond the point of distortion.

Placing Your Subwoofer in a Room
Your PSW Series subwoofer is not magnetically shielded. Do not place near video monitors. (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.
Suggested Speaker Placement
Suggested speaker placement with options for rear speaker placement. Subwoofer should be placed more than six inches from wall anywhere in the room.
Note: Additional satellite speakers may be purchased for 6.1, 7.1 or 9.2 surround systems by contacting Polk customer service at 1-800-377-7655.
SUB
18" - 24" (46 cm - 61 cm)
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. 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. 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.

System Hookup Options
Important: Use only one of these options. Never combine hookup options.
Option #1
Receivers that include a “Sub Out” feature—the most common hookup method with Dolby® Digital receivers.
Note that one of the speaker input 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 receiver to the red (+) terminal on your speaker, and the wire from the black (–) terminal of the receiver to the black (–) terminal on your speaker. Speaker wire has some indication (such as color coding, ribbing, or writing) on one of the two conductors to help maintain consistency. 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.
Note: Use either the L or R Line input (another hookup option is to use a Y-split cable and connect both L and R line inputs). After you make this sub out connection, turn the “Low Pass” filter fully clockwise.
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.”
Receiver Settings: Front, Center, and Surrounds = “SMALL” Subwoofer = “ON,” or “YES,” or “PRESENT” Set the crossover frequency on the receiver to 120 Hz.
Consult your receiver’s owner’s manual for speaker configuration.

Option #2
Two channel or Dolby Pro Logic receiver with no “Sub Out.”
If you elect to use the speaker level inputs, use two-conductor 16 gauge or thicker speaker wires. See your Polk dealer for wire recommendations.
Note that one of the speaker input 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 receiver to the red (+) terminal on your speaker, and the wire from the black (–) terminal of the receiver to the black (–) terminal on your speaker. Speaker wire has some indication (such as color coding, ribbing, or writing) on one of the two conductors to help maintain consistency. 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 unfrayed strands.

Adjusting Your System
Subwoofer Adjustments
Your powered subwoofer offers a range of setting options. We recommend the following settings as starting points, but the settings that are best for you depend upon your speaker 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: http://www.polkaudio.com/polk-university/articles/bass­management-and-subwoofer-connections.
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. Start with the volume at 50%.
AC Power Connection and Auto On/Off
Your subwoofer features auto on/off circuitry, marked “auto” on the power switch, which automatically turns your subwoofer on when it senses a program signal. We recommend the “auto” setting if your subwoofer is always receiving power (ie, if it’s plugged into a wall outlet).
When no signal is present, the circuit turns the subwoofer off after 15 minutes. If you are concerned about the brief delay between when the music starts and when the subwoofer turns on, simply leave your subwoofer in the “On” position. You may want to leave your system unplugged during extended periods of non use, such as during a vacation.
Fine Tuning Your Subwoofer
•Volume—Adjust by ear using a wide variety of CDs and video sources. Adjust for deep, powerful bass without “boominess.”
•Low Pass—Note: This control should be turned all the way up when the subwoofer is connected with Method #1 (LINE IN). This control adjusts the frequency range over which the subwoofer operates. 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.
•Phase Switch—Sit in your favorite listening position. 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. Sometimes no difference will be heard.
