Polk Audio DSW PRO 660wi
Our take on the Polk Audio DSW PRO 660wi by Crutchfield's Kristen Schaub
Deep bass you can hear and feel
Rumbling spaceships, thunderous explosions, the smooth, sonorous tones of a double bass — Polk's DSW PRO 660wi can handle just about anything you throw at it with power and precision. It features a 12" woofer driven by a potent 400-watt amplifier, capable of filling even a large room with deep, rock-solid lows. This authoritative sub uses Polk's exclusive Feed Forward™ technology to reduce audible distortion without limiting volume. You get quick, precise response throughout the sub's entire frequency range, even at room-shaking volume levels.
Sounds great no matter where you place it
The PRO 660wi also includes the Polk Room Optimizer™, an ingenious feature that lets you specify the location of your sub with one of four options — corner, mid-wall, in-cabinet, or mid-room. The Optimizer then automatically equalizes the sub's response to ensure smooth, clean bass from that position. You can easily access this function, as well as the volume control and phase switch, with the included remote, so you can fine-tune the bass from your favorite listening spot. Removable feet let you position the PRO 660wi for either front-firing or down-firing operation, whichever you prefer.

Driver: The DSW PRO 660wi uses a 12" Dynamic Balance composite polypropylene 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 Audio is able to optimize the woofer's motor structure, voice coil alignment and suspension for the best possible performance even at extreme listening levels.
Class D Amplifier: The subwoofer is powered by a high-current Class D amplifier producing 400 watts RMS power (800 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. The efficiency of a Class D digital amplifier translates into high-power, and cool, reliable operation with low distortion.
Feed Forward Distortion Suppression Technology: This technology maximizes acoustic output as it reduces audible distortion. Feed Forward is a zero latency system that maximizes dynamic output of the subwoofer system without relying on slow responding feedback techniques. What you'll hear is quick, precise bass output with minimal audible distortion, even at loud volume levels.
Enclosure: The DSW PRO 660wi features a bass-reflex enclosure with non-resonant MDF construction and internal bracing for deep bass impact with superior detail and accuracy. The subwoofer's enclosure's durable onyx black finish can be painted to match your room decor, if desired.
Downward Radiating Slot Port: The DSW PRO 660wi features a downward radiating slot port which lessens turbulence, noise and distortion. The result is deep, clean and accurate bass.
Video Shielded: The DSW PRO 660wi is magnetically shielded for placement near video monitors. You should still allow at least 18" of space between your subwoofer and any tube television. LCD, DLP and Plasma TVs are not affected by magnetism.
Frequency Response: The overall frequency response for the subwoofer is 20-160Hz, and the -3 dB frequency response is 25-125Hz.
Repositionable Feet: The DSW PRO 660wi features repositionable rubber or spike feet which allow you to orient the subwoofer on its "back" to turn it into a front-firing woofer when you want to hide the subwoofer away in cabinets. There is an optional woofer grille (item # 107DSW600G, sold separately) available when the subwoofer is used in a front firing application.
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.
IR Wireless Remote Control: The DSW PRO 660wi comes supplied with a credit card sized IR wireless remote control which operates the following subwoofer's controls - Volume, Mute, Phase, Night and Polk Room Optimizer. 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 its downward firing configuration. There is a blue LED behind the woofer's logo badge which blinks to confirm the subwoofer has received and responded to the remote's instructions. The LED feature can be turned off.
Note: The subwoofers crossover setting must be set using the controls located on the rear panel of the woofer.
Polk Room Optimizer: The DSW PRO 660wi's remote control incorporates the Polk Room Optimizer (PRO) feature. The Polk Room Optimizer feature allows you to place the subwoofer where you want it in your listening room. Based upon the four most common room placements for subwoofers, the Polk Room Optimizer maximizes sound quality for you, smoothing out the bass response that a particular room placement creates. There are four push-button room equalization presets on the remote that correct for room boundary effects for typical room placements: "cabinet," "corner," "mid-wall," and "mid-room." The result is great bass performance no matter where you place your DSW PRO 660wi subwoofer.
Night Mode: Night Mode compresses the dynamic range of the woofer's output, so you hear low-level bass detail at lower volumes.
Volume Control: The DSW PRO 660wi has a push button volume control to adjust the volume of the subwoofer relative to the other speakers in the system. The volume is adjustable from 0 to 40. The blue LED on the front panel will indicate the volume level using a combination of short and long blinks. The volume can also be adjusted using the supplied wireless remote.
Phase Switch: The subwoofer's IR wireless remote features a phase control which allows you to select 0-degrees (normal), 90-degrees, 180-degrees (reverse) or 270-degrees. This control enables the subwoofer to blend more seamlessly with your main speakers. If the bass sounds muddy or unclear, using the phase control can sometimes strengthen the bass "attack."
Low-Pass Filter: The DSW PRO 660wi offers a continuously variable low-pass filter, adjustable from 60-120 Hz. The cut-off frequency must be manually set from the subwoofer's control panel.
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, red when the unit is off and yellow during standby mode.
Note: If the receiver's subwoofer output is unfiltered, you should use either the left or right Line Input of the subwoofer.
Line (Filtered) Inputs/Outputs: The subwoofer has gold plated left and right RCA Line Level inputs. The inputs are for use with electronics featuring unfiltered "Pre Out" jacks (Example: a separate pre-amp processor with a separate amplifier). It may require "Y adapters" to connect the left and right outputs of the pre-amp processor to both the subwoofer and the power amplifier. The line outputs allow you to send a filtered signal to a power amplifier to drive bookshelf speakers.
Speaker Level Input/Output: The subwoofer has 5-way binding post connections for front speaker level input and output. The subwoofer's low-pass filter takes the low frequencies (based on the setting of the filter) and sends it to the subwoofer. The speaker level outputs send a filtered signal to your connected speakers.

Why did you buy this?
I currently have Polk Audio RTI Tower Speakers. I'm replacing my older Polk Audio DSWPRO600. [ STEVEN Aug 21, 2018 ]
Paired my Klipsch Forte IIIs with the DSWPro 550wi that had been hanging around here and think that this is one of the best I have heard. Though the Forte IIIs don't rneed a sub, the combo is beyond awesome, especially with Bach and LIszt organ pieces, so will pair my other pair of Forte IIIs, in a larger room, with the 650. And, of course, Crutchfield! [ Charles Jul 13, 2018 ]
I have had Polk products before and have always been a fan of there sound quality. [ Curtis Feb 01, 2018 ]
I already own Polk RTi12 speakers. This SW has good reviews and lots of power for home theatre use. [ Thieng Jan 22, 2018 ]
Outfitting my son's house and I have this product and it is awesome. [ Jeffrey Oct 10, 2017 ]
To go with RTI A9's. I am also looking to buy another 660wi. Waiting for it to go on sale. [ Hari Sep 20, 2017 ]
This subwoofer meets my space, power, and performance requirements. I like the Brand's reputation, and I appreciate the favorable user reviews. A bonus is the auto on/off power feature. [ Terry S. Jun 11, 2017 ]
I have had a 10" Polk Audio sub for several years. While it worked well, the amplifier gave out and I decided instead of replacing the amp, to just upgrade to something larger as my new living room is much larger. After reading the reviews and comparing prices, I couldn't pass this one up at $499. [ Randy May 11, 2017 ]
After researching and using Crutchfields advisors I decided to purchase for my new home theater room. [ Keith Dec 31, 2016 ]
Option to change from front or downward firing. Also size needed for room. [ Bryan Dec 31, 2016 ]
Amazing sound, upgraded from 10". [ William Dec 18, 2016 ]
I chose this based on customer reviews. [ Kevin Dec 05, 2016 ]
Best sub I've ever had thinking about another for the 7.2 i need to feel whats happening behind me also [ COURTNEY J Nov 26, 2016 ]
Replaces the one I had. [ L Nov 12, 2016 ]
My buddy has a 15 year old Polk Audio dual 10" home sub that still shakes the block. I wanted a top end sub that does the same. [ Richard May 08, 2016 ]
Superb sub for a home theater. Unless, of course, you have a $30K setup, in which case you may want something else :) But in all seriousness, the difference it makes is amazing. You know, it senses the source signal and turns on after a few seconds by itself. So you start with a sound just through the speakers. For me, that's a standard 5 channels. Then this thing comes on and it's an instant "Wow".... Highly recommended. [ ALEX Feb 02, 2016 ]
I want something that will thump my whole body when listening to music or watching a movie. [ Todd Jan 17, 2016 ]
Strong unit. I have three others [ JEFF Jan 09, 2016 ]
PRICE AND SOUND QUALITY CAN'T BE BEAT. [ RAFI Jan 07, 2016 ]
Compatible with RTiA9's [ PETER Dec 21, 2015 ]
Purchased one of these units 2 years ago for the family room and it is great. I have my movie room done and I would not want a different sub in there... [ Jeff Dec 18, 2015 ]
Already own one of these subs, adding a second it sounds so great!!! [ Steven Dec 10, 2015 ]
3 questions already asked
I use this sub to power my main entertainment area in my basement. When we watch movies or play music loud the base is felt through 3 levels of the house. I do find my self having to turn down the gain for bass heavy music. I have operated this sub both wirelessly and directly with a long rca type wire. Works great both ways. I initially set up the room with an additional sub but realized I didn't need it. I have been very happy with its performance. [ GUNTER May 28, 2016 ]
2 answers Hi, I've been researching this sub for months. I currently have 2 PSW505's running in an Onkyo 818. Would one or two of these give me the same punch and boom as my 2 505 or better? I'm looking for a tighter solid "feel it and hear the rumble than what I have now. I get some really deep rumbling wall shaking bass from these but, I like the wireless feature and Phase controls Bc 818 doesn't have bass management for 2 subs. Also have tile floors, anyone heard this on hard floors? Doesn't seem to be a lot of reviews anyway on 660, has anyone compared them to the Valendine wireless? Any help would be greatly appreciated. A~ [ Aaron Dec 04, 2014 ]
I have mine behind a door leading out to a hardwood floor. Room is about 15' by 12' Unit carries a very nice punch and sub rumble, I like the controls to fine tune the sound. Id recommend, although I haven't compared to the Val. [ MICHAEL A Dec 06, 2014 ]
i've been satisfied with sound on hardwood floor but can't compare to your current model. Rumble is good with video. I've been dissatisfied with wireless - there is a lot of interference when turned on but not in use, like when walking between transmitter and speaker, and I think sometimes when in use. I'll probably switch to wired. [ THOMAS J Dec 05, 2014 ]
I forwarded your question to an Advisor and they responded with the following: The Yamaha RX-A2000 has a standard subwoofer pre-amp output that is compatible with the Polk subwoofer. You will need to use a mono RCA/subwoofer cable to connect the two. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat.
