Pros: Price and performance. At $80 to $100 this sub is optimal for any entry level surround system or as a 2nd sub for 7.1 or 5.2 using 2 subs, use this in the rear set the amp to 70hz+.

Puts out decent bass and good for movies if faced toward a corner wall in the back. Music may lack on this past 1/2 volume using the gain on the back.

Cons: Port chuffing is incredibly annoying when going past 1/2 on the back of the sub with the gain. This is extremely noticeable when below 50hz past 1/2 on the gain. If you turn it beyond 1/2 and go to below 50hz you experience large port chuffing because this subs design doesn't eliminate or protect against port chuffing since it is an entry low priced subwoofer.

Other Thoughts: I would not recommend this as your 5.1 or 7.1 or higher main sub for rooms larger then 14x12 or similar size. Larger rooms you would need to turn it up more and then you create the problem of port chuffing this sub is notorious for having. Annoying when you hear the chuffing noise.

Pros: Puts out good bass. Decent price

Cons: none

Other Thoughts: Bought this almost 3 years ago and it is still chugging along perfectly. Figured after 3 good years out of that baby I should throw a good review on here

Pros: Good looks
Many Adjustable Features
Great Bass
Better than others I've had

Cons: This thing is a lot bigger than I expected!

Pros: Price is incredible 120$ or less is a steal for this Sub
This Sub Sounds great for Music/Movies and games i don't know why anyone would say other wise unless their teaming this up with Tall Fronts which Polk does not recommend or have a Old receiver that can't send a Clear single to it which is possible.
It's not unclear either its pretty clear with a good receiver
It works perfect on my 5 year old pioneer which I'm replacing in less then 3 months.

Cons: People who turn the Amp to 100% on a 100$ Sub or people who complain about their is no LFE when you can buy a Y-adapter for less then 2$ on newegg.

Seriously i see No need to set this Sub past 50% and that's what Polk recommends! I also turned the Cross-Over frequency at max and left phase to 0 and bought a y-adapter(apparently its fine if you just plug the RCA cable into the left channel)

Other Thoughts: This was my first Polk audio purchase And i'm going to complete the set with Monitor 40 Fronts and Monitor 30 rears and a CS1 Center, This whole se-up will cost between 350-400$ with the sub included which is also a steal! Polk is by far my favorite brand To my opionen their the best you can get for the money and i really researched like crazy and to me no brand comes close to Polk besides Bose which i say no to. Just don't Buy this Sub expecting it to keep up with the Monitor 70's Polk recommends The set-up I'm doing with this Sub so take advantage of it and use their info. http://www.polkaudio.com/homeaudio/products/recent/monitor40/

Look at the URL to see The proof.

Pros: As suggested in the title, these translate a lot of the feel of your typical cinema. Auto-on and powersave works well. Heavy, but less-so in the box than the Monitor 40 pair in it's box (a major blessing during my recent move). Effect is pronounced at just 50% volume/gain setting on the rear knob, but I asked repeatedly yet my apartment neighbors say they can't really hear it from their rooms... Yay polite! Finally, doesn't distort like subwoofers included in HTIB kits (which I hated even when turned down low).

Cons: Lacks bass detail compared to headphones in the same price range.

Other Thoughts: I use a cheap Ratshack RCA cable to connect to my reciever's subwoofer out port. Leaving the other channel unplugged doesn't hurt anything.
By the way, you CAN'T use the subwoofer as your amp or DAC to power speakers. The left/right in and out speaker wire terminals are on a separate circuit than the RCA jacks, and are only provided in a worst case scenario if your integrated amplifier doesn't have a dedicated subwoofer out port. So you can't plug this directly into most computers.

Pros: Great Sounding Sub, Compliments my Monitor 60 Front Speakers and my CS1 Center Channel tremendously. This Sub pounds HARD!!! Gives the bass that the Monitor 60 Lacks. Has a great range, but does flutter a little on the more deep-end bass ranges. None-the-less for 89.99 on sale you can't beat this sub, if your on the fence, dive in and buy this baby. Wait for a sale though as it goes on sale regularly.

Waiting on my Monitor 30's for my surround speakers to finish my all Polk Audio Surround!

Cons: None!! Buy this thing and enjoy that deep/clean hard hitting bass your surround system deserves!!!! :D

Other Thoughts: Can't wait to get my Monitor 30's to finish off my all Polk Audio Surround. Polk Audio has always been the best bang for your buck in terms of quality/prices. As stated earlier wait for sale though as NEWEGG often puts There Polk Audio Speakers on Sale for great prices. Throw in Free Shipping and you can't beat hedeal

Pros: Got one of these 5/24/2009 and it's still pumping out the bass! Plenty for the smaller living room we have.

Cons: none

Other Thoughts: And considering it was less than a C note on a Shellshocker deal, this has been FANTASTIC!

Pros: * Solid construction (it's heavy 31#)
* It has a decent sound given it's < $100 as of 10/18/12.

Cons: * Didn't come with cables like my M-Audios 40.
* Rattles when Volume is set above 80% so I set mine to around 70%.

Other Thoughts: PSW10 is paired with M-Audio 40 routed to my RealTek Audio. Plug sub into center/sub. Plug m-audio into L/R. Download Realtek HD Audio Manager. Set to 5.1. Test. Turn off the two rears and center. Check the box for enable bass management and filled...BOOM! 2.1 Stereo system on a PC. Sounds great but the bass could be better but again it's less than $100 WTFlip do you expect right? Buy it unless you want to spend $400 or more.

Pros: I have had this sub for almost 2 years now. It still works just as great as it did the day I took it out of the box. This sub shouldn't be used for any professional sound equipment. But it definitely does the job if all your going to use it for is a home theater system. I use my sub for listening to a lot of music, a lot of time at high volumes. It seems to take whatever I throw at it with out to much of a problem. Great sub. I recommend it.

Cons: None that I can come up with.

Pros: Great sound and user friendly. Easy to set up.

Cons: None found yet.
