Product Description

From the Manufacturer

Have a big room? Have the need for BIG, life-like bass impact? Then the PSW505 is the subwoofer for you. More than a mere brute, the PSW505 is equally at home reproducing all the subtle nuance of a plucked string bass as it is belting out a rocket's roar. Full-featured and over-powered, the PSW505 will rock your world.

Key Features

• Slot Load Venting improves bass response. The wide, long slotted vent dramatically lessens turbulence, noise and distortion, creating precise, thunderous bass!
• Polk subs sound better because they're built better. Rock-solid MDF construction (including a 1 inch thick front baffle) suppresses enclosure panel resonance for distortion-free, accurate response.
• Big 12-inch Long Throw Driver for longer excursion and better linearity.
• Adjustable low pass crossover, phase switch and volume control allows perfect blending with any main speaker.

Why you should consider this product

Big subwoofer performance pure and simple. If you’re ready for room filling, chest-thumping high impact high performance bass, the PSW505 is the perfect choice.

Take a look inside this product

• Huge Hi-Roll Surrounds that support a true long throw driver.

• 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.
• Unfiltered LFE input for use with low pass filtered subwoofer output jacks.
• Pro-grade 5-way binding posts speaker inputs and outputs.
• 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!

5.0 out of 5 stars Dripping with bass September 22, 2009

By Money Leaker

Amazon Verified Purchase

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. The LFE goes straight to your sub's amp whereas LL first goes through your sub's built-in crossover and then from there to your sub's amp. If you plug LL into the LFE input, you'll be asking the sub reproduce the full sound spectrum. Not what you want, of course. Probably not a big deal whether you use one or the other. The Polk's built-in crossover is fine, i'm sure, but I'd rather do the crossing-over at the A/V unit level.

c) Apparently, a good powered sub has an ON/OFF/AUTO switch, a 180-degree phase-change switch, a volume control, a cross-over level control (this control is not functional if you are using the LFE), a LL input (or two), an LFE input, and a Left/Right channel speaker-level input and corresponding outputs (for a total of 8 speaker wire connectors).

d) The unit seems very well built with what feels like sturdy wood (or MDF) and is somewhat heavy. Which is a good thing. It feels reassuringly sturdy/massive.

e) Would I buy this sub again? Well, I've discovered that many of the wonderful items that are for sale at Amazon are no longer being produced. IE, they are discontinued by the manufacturer. Do a product search at polk.com and you will no find this sub (you can do a search in the product support section to find its corresponding literature pdf). I just guess that that is the nature of the beast. Great products sooner or later get replaced with even newer & greater products. The older and merely "great" (not "greater") products still need to get cleared out of the inventory so they wind up at amazon.com or other e-tail sites. So, despite the fact that this sub is no longer in production, no longer supported, and is probably a year or two or three (or more) old... would I still buy it again? HELL YES!

5.0 out of 5 stars Low and Tight November 7, 2008

By Balashark

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!

5.0 out of 5 stars Great sound from a Great company October 30, 2007

By Harry Bulgari

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.
