Product Research



Driver: The Polk Audio PSW110 uses a 10" Dynamic Balance composite cone driver for deep, accurate response with low distortion. For a smoother response and improved durability, the woofer utilizes a rubber surround.

Klippel Optimized Woofer: By using a state-of-the-art Klippel Distortion Analyzer, Polk is able to optimize the woofer's motor structure, voice coil alignment and suspension for the best possible performance even at extreme listening levels.

Motor Structure: The PSW110 utilizes a powerful motor structure for a higher BL responses (the measure of the motive force applied to the cone) that results in louder, deeper and punchier bass.

Compression Circuitry: The woofer's Compression Circuitry limits distortion at high volume levels.

Amplifier: The subwoofer is powered by a high-current amplifier producing 100 watts RMS/200 watts dynamic power that supplies clean power for loud bass and a wide dynamic range necessary to recreate a life-like experience in your home.

Enclosure: The PSW110 features a bass-reflex enclosure with non-resonant MDF construction and internal bracing for deep bass impact with superior detail and accuracy.

Down-Firing Port: The powered subwoofer's downward firing port allows the woofer to be extremely efficient and provides more bass impact for your home theater experience.

Not Video Shielded: The subwoofer is not magnetically shielded, so it is not recommended to place it next to tube TVs and video monitors. Though LCD, DLP and Plasma televisions are not affected by magnetism you should allow at least 18" of space between the subwoofer and any TV.

Placement: You may place the subwoofer anywhere in your room, but it will perform best when it's on the same side of the room as your system's front speakers. Also, placing the subwoofer near a wall or in a corner will increase its loudness.


3-Way Power Switch: The subwoofer has a 3-way power switch on the rear panel. You can select Auto, which turns the unit on automatically when an input signal is received and off 15 minutes after the signal stops; On, which keeps the unit on and Standby, which turns the unit off. The LED power indicator glows green when the unit is on and red when the unit is off.

Volume Control: The PSW110 has a rotary volume control to adjust the volume of the subwoofer relative to the other speakers in the system.

Phase Switch: The subwoofer's phase switch allows you to select 0-degrees (normal) or 180-degrees (reverse). If the bass sounds muddy or unclear, toggling the phase control can sometimes strengthen the bass attack.

Low-Pass Filter: The PSW110 offers a continuously variable low-pass filter, adjustable from 60-160 Hz. There is an LFE position for use with the filtered LFE output from a receiver or preamp.


Line Inputs: The subwoofer has gold plated left and right RCA line level inputs for use with receivers having subwoofer or stereo preamp outputs that do not contain their own low-pass crossover. Using the Line Inputs allows PSW110 to do all the low-pass filtering. If your receiver or processor only has a single subwoofer line output, connect it to the Right line input jack.

LFE In: The right channel RCA input doubles as the LFE input; if your receiver has an LFE output and a built-in crossover, use this input and set the low-pass filter dial to LFE.

Speaker Level Input/Output: The subwoofer has spring clips for the speaker level inputs and outputs. The subwoofer's low-pass filter sends bass frequencies (based on the setting of the filter) to the subwoofer. The speaker level inputs and outputs are shorted together, so the output is not crossed over. You should set you receiver's front speaker setting to Large.

Customer Q&A

10 questions already asked

I'm interested in getting this sub, but I'm not quite sure what cable/s i need. I have a Sony STR -DH790 receiver that has left and right designated sub outputs. Do I need two RCA cables to connect to this sub, or one sub cable from the LFE/right input on the sub to the right output in the receiver? Thanks

I used designated subwoofer cables. They are like rca cables, but they are heavy duty and shielded.
[ roadrunner  Nov 30, 2019 ]
You just need one RCA cable. Just like you have written in your question. Connect the cable to the LFE/right input on the sub. Adjust the sound to your listening pleasure.
[ Ronald  Nov 30, 2019 ]
Plugged my PSW110 in and as soon as i plugged in power a constant distortion buzzing came from sub can you guys tell me what is wrong??

Enter an answer to this question.Good afternoon, write Rachel's husband, Danny. In relation to the Polk subwoofer, you must check the receiver's connection and see that this child is making that noise (ground), in addition, you must connect it only in the red color input, I hope you can solve it.
[ RACHEL  Oct 25, 2018 ]
Sounds like a bad amplifier. If you can't return it to Crutchfield then call Polk's customer service. I believe this sub has a 3 yr warranty if my memory serves me. The amp went out in my sub and Polk shipped me a new amplifier. A ten or so minute job and my sub was as good as new. Good luck!
[ MICHAEL  Oct 25, 2018 ]
I am no expert but, it sounds like either you got a bad cable or the connector maybe be bad on the unit. You could also try moving the unit sometimes depending on your other components they could thru off signals that could cause issues. I am sure the Crutchfield folks will help you or replace your unit.
[ Matt  Oct 25, 2018 ]
First disconnect your amplifier from the speaker, removing the connection at the speaker. If the noise stops, the problem is either in your amp or the connecting wiring. Assuming that the noise stops when the speaker is disconnected from the amp, check your wiring from the amp to the speaker. There could be a short circuit in the connectors. A high resistance short could be the issue. Assuming that the wiring is good, the issue is in the amp itself. Of course, if the noise continues when the audio cable is completely disconnected from the speaker, there is a problem with the speaker itself.

Crutchfield tech needs to address this. If it's not a crossed wire somewhere adding the buzzing to your input, then maybe faulty item. Test item with another connection to another device, another tv or something.
[ Andrew  Oct 25, 2018 ]
My first guess would be to check to make sure the connection is all the way in. They will totally distort just the way you described.
[ Jason  Oct 25, 2018 ]
I have the same problem...never contacted them but I unplug it it's annoying if you hear back from them let me knowEnter
[ BRANDON  Oct 25, 2018 ]
Do I need to connect my speakers to the back of the sub even though I have a receiver?
[ Matthew  Sep 27, 2017 ]
2 answers
You have two other options. If your receiver has a sub out rca jack ,use it with a sub cable to the LFE input on the speaker (most common set up). If you have a pre-out you can run right /left rca cables to sub.
[ LAWRENCE  Dec 10, 2017 ]
No you can connect it directly to the sub out in the receiver.
[ Jeffrey  Sep 28, 2017 ]
Is this subwoofer dual voltage? (115-230)
[ Benjamin  Jan 06, 2017 ]
1 answer
No. The unit does not have a voltage selector on its back. Only the 2-prong AC conector for the included cable.

[ JOHN  Mar 28, 2016 ]
It cannot be removed
[ CHRIS  Mar 27, 2016 ]
My Yamaha receiver just has one RCA jack type input. What is the best hook up for this sub woofer? Is there a cable the has one input for the receiver and 2 for the sub woofer?
[ Steve  Apr 29, 2014 ]
1 answer
I forwarded your question to an Advisor and they responded with the following: Powered subwoofers have two RCA (left and right) inputs for when you are connecting from a receiver that doesn't have a designated subwoofer output. But when you have a home theater receiver with a single, mono subwoofer output, you need a mono subwoofer cable, such as this one, to connect to, in this case, your Polk Audio PSW110B powered subwoofer. And you need to connect the sub cable into the Right RCA input (not the Left) on the PSW110B. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat.

Can it be hooked up to an already pwered tv speaker bar that came with out a sub-woofer?
[ Gil  Nov 30, 2013 ]
1 answer
As long as the powered TV speaker bar has a subwoofer pre-amp output any of the powered subwoofers should work great.
