  • High current 300 Watt Continuous (460 Watt Dynamic) power amplifier.
  • Adjustable low pass crossover, phase switch and volume control allows perfect blending with any main speaker.
  • Auto on/off circuit that automatically turns your subwoofer on when it senses a program signal. When no signal is present, the amplifier turns off within 15 minutes.

  • Magnetically shielded for safe, flexible placement next to a TV or video monitor.

Technology

Dynamic Balance® Woofer Design Polk perfected the method of analyzing a speaker's microscopic behavior with laser Interferometry. With that information in hand, Polk engineers select the ideal combination of materials, geometry and construction techniques to literally “tune out” unwanted resonance. The result is a subwoofer that delivers pure, distortion free deep bass.

Klippel Optimized Long Throw Woofer Using a state-of-the-art Klippel Distortion Analyzer, Polk engineers optimized the woofer's motor structure, voice coil alignment and suspension for longer excursion and greater linearity bringing you the best possible performance even at the most extreme listening levels.

Slot Load Venting improves bass response. The wide, long slotted vent dramatically lessens turbulence, noise and distortion, pouring out a tidal wave of precise, thunderous bass!

Rock-solid MDF construction (including a 1 inch thick front baffle) suppresses enclosure panel resonance for distortion-free, accurate response. Polk subs sound better because they're built better.

1To ensure a valid warranty, Polk loudspeakers must be purchased at an Authorized Polk Audio home or car loudspeaker Dealer (such as Amazon.com). (If you're not sure a dealer is "authorized," call Polk Audio at 1-800-377-7655, and ask us.) The warranty is not transferrable, that means it applies only to the original purchaser. If you purchase your speakers from a private individual, that product is considered "used" and has NO factory warranty, no matter what the seller implies. The warranty is VOID if the serial number of the speaker has been removed or defaced. If you have any questions about your warranty coverage, or you think you need service, call Polk Customer Service at 1-800-377-7655. We're here to help you get the most from your new speakers!

Bass is clear, deep, oh, and LOUD! If you really want your HT to sound like an IMAX theater, then I whole-heartedly recommend this sub. It fills in the low end seamlessly. It also takes the burden of reproducing low lows off of your other speakers (which aren't nearly as capable as the PSW505). This is not a cheap "rumble box". The first movie I watched with this sub connected is Peter Jackson's "King Kong". The raptor/bronto chase through the gully is off the hook! The 30-ton bronto's gallop will set up a standing wave in your intestinal tract!!! But loud does not mean muddy or rumbly with the 505. I was pushing the sub to about 50% volume and I thought my house's windows may break. And like I said, that was only at about 50% volume. Besides, you want to be a good neighbor and not max this thing out cuz it can be heard clearly from a good 50 feet away. I find that it performs exceedingly well at about 15% of its capability in my medium/small sided living room. At normal/reasonable volumes, this sub recreates the super lows that truly make the difference between listening pleasure and listening rapture. No HT is truly complete without a sub and this one fits the bill to a tee.

a) I definitely WOULDN'T recommend this product if you live in a dorm/apt/condo/townhouse. This thing has the sonic capability to really anger your neighbors.

b) This sub is one of the few in its price range that actually has an LFE input (Low Frequency Effects) in addition to LL & speaker-level. I you didn't know, LFE & Line-Level (LL) inputs both use an RCA connector. The difference is that the LFE channel carries only low freqs from source whereas LL carries the entire sound spectrum.

Was very iffy on this sub since I was going from a $1,000 Velodyne to this, but let me tell you I am not disapointed.Low tight bass with no distortion or rumble, sounds much better playing music than the Velodyne did,even though I use it mainly for movies.In my opinion you are getting a high end sounding subwoofer for $300, there is no way you can beat that!Tried to see how loud I could take it to see at what level it would start to distort, but could not get there because my windows were about to pop And my nose started to itch from the tremendous vibration, teeth rattled a little too! trust me I am not exagerating! BUY THIS SUB!!!!!

Update: YES March 10 2012 and this sub is still going strong....Amazing!

Polk Audio is still making great speakers. I bought my first pair almost 30 years ago in 1978, had them for almost 25 years till I replaced them with smaller ones with a Velodyne sub. When my overpriced Velodyne sub went out on me last month, I decided to give Polk Audio a try since my first experience with Polk was so good. All I can say is that I'm glad I went with the 12" and for the approx $300 price tag, it sounds as good if not better than my high end $800 Velodyne sounded. For the extra $75 or so, get the 12" as opposed to the 10", you'll be glad you did.

This is a great budget sub for those looking to get their feet wet with home audio, for someone that has never had a sub before, or is upgrading from a HTIB (Home Theater In a Box). I currently have this sub and have been using it for 2 months. Polk has a longstanding reputation for building quality products and for excellent customer service. If you're considering the PSW10, don't as for a little more money this sub is in a completely different league and I have owned both.

Pros:

- Price
- Good sound for the money
- Decent looking sub
- Decent sound quality for home theater or music
- Provides a good amount of bass for a medium size room (20x15)

Cons:

- Doesn't go very low. I believe this sub is tuned at 35Hz from reading reviews, and it drops off sharply after that. Unfortunately, this is where a lot of the sound is in movies where you'd want a sub to perform well. For music, it's less likely going to be an issue. In my own experience, I played a couple of bass test songs (Bass, I Love You and a frequency sweep) and found the same to be true. On the lower notes this sub simply loses it's composure under the tuning frequency, which is to be expected as there's no acoustic load for the driver under that. The end result is that the driver flaps freely and there is concerning port chuffing (noise) and simply a lack of output.

Suggestions:

- At this price point there are few competitors to this sub. The BIC America F12 12-Inch 475-Watt Front Firing Powered Subwoofer has gotten better reviews than the PSW505 and will play lower and likely sound better doing it.

I have been in the process of slowly replacing my speakers, going from an old set of conventional 3-way Altec Lansings (w/Bose surround satellites and a Boston Acoustic center channel) to an all-Polk Audio 5.1 configuration. Over the last few months, I purchased a set of Polk Audio RTI A7s for my fronts, a Polk Audio CSI A6 Center Channel, and a pair of Polk Audio RTI A3s which serve as rears. The new speakers offer great clarity and response across the mid- and high-range (they are all voice matched so it sounds great) but they are a bit lacking in terms of bass as compared with the old Altecs, which featured a 12" woofer and a lower -3db limit of ~30Hz, rendering a subwoofer unnecessary. I needed that little super low-end "thump" I used to have (the A7s, the most responsive speakers I own at the low-end of the sound spectrum, have a lower -3db limit of 35Hz), and after reading the reviews here this sub seemed like the best combination of performance and value. I purchased this item from Amazon and it arrived in 3 days' time. Plugged it in and all I can say is wow. I have a medium-sized room, and this product has no problem providing the low-end bass I need without breaking a sweat. The PSW505 is self-amplified, and I have it set at less than half of max volume. At its current setting it is more than suitable. When I crank it up, it makes the entire room shake, and literally rattles my teeth.Read more ›
