  1. JohnnyH –

    This is my honest review from somewhat an audiophile and bass head *been having subs in my cars since I started driving* lol for movies this will definitely shake and vibrate your house and floors and sometimes you can feel it in your chest depending on the placement *I got mine in a corner which is recommended for heaviest bass*
    For music it is kind of lack luster, can easily hear the distortion kicking in on newer bass heavy songs especially rap/hip-hop and it honestly sounds terrible when the distortion hits, but that’s only if you turn it up enough, I find myself having to constantly turn it up or down depending on if I wanna listen to music or watch movies in my home with this sub, if you’re not really a bass head or a big speaker guy it definitely gets the job done but is it worth $400? To be honest no. you’re wayyy better off with the klipsch R-112SW going for $429 at the moment *not sold at Best Buy unfortunately* don’t go for the $600 R-121-SW-II sold at Best Buy because the $429 R-112SW hits harder, has more power output and also won Crutchfield’s 2023 top selling subwoofer for a reason. Just giving my advise because I’ve been looking for a good subwoofer on a budget and it’s not easy.

    I do like all the adjustments on the back of the subwoofer though is defined useful.

    Final conclusion: gets the job done and sounds good with movies when there isn’t distortion, but when there is distortion especially with music it’s definitely annoying and doesn’t sound pleasing at all. If I got this on sale for $299 or under it wouldn’t be too bad of a deal then.

    Hope this review helps others.

  2. Garrden –

    Was running a home theater setup for a while without a sub and this brought it to a whole new level. Clean bass and the knobs let you find that perfect balance

  3. TravisN –

    Great low end at an affordable price. Very adjustable with volume, frequency, phase control and multiple inputs/outputs.

  4. RichardP –

    I bought this durning Christmas time December 29, 2022. I did not open the box until June 2023. Found out it was defective. It crackles when it play low bass tones. Best Refuse to exchange it, return policy is only 14 days of purchase, not including un-opened box of items, you own it, whether bad, defective or good. I cannot use it, am told it is under warranty to have Polk repair it.

  5. WJ12 –

    Awesome subwoofer. Will shake the whole house if you want it too.

  6. DerekjM –

  10. Kevin –

    More than i expected. An average size living area can be totally dominated with plenty left over. Clear bass.

  11. Unknown –

    It’s great. Everything I wanted and more .It performs flawlessly. I will probably buy another one in the future.

  12. LeshelbiaC –

    IT IS SMALL AMD FASHIONABLE HOLDING ALOT OF BANG MEANING BASS!!!

  13. TracytB –

    Awsome speaker! Bass is great especially for my small room . Hits perfectly!!

  14. ChrisC –

    Sounds great! Easy plug and go! Does raffle my windows so pretty deep and loud! Not deep like car subs

  15. ScottG –

    Sounds great.
    This thing is a game changer….
    I would definitely recommend….

  16. DavidP –

    Not yet installed yet I have every confidence in this Geek Squad team to correctly install this speaker.

  17. NavneetK –

    Best sound quality! Have the product for one year, still works like brand new.

  18. JoJoTheJo –

    This sub is clean… within limits. My house has an upstairs landing where two of the “walls” are non existent and overlook the downstairs. With that, this sub does not get the benefit of reflection. A lot of the bass waves get lost to the great abyss that is my two story living room. So after some trial and error, I did find a place to put the sub where I do get some bass response for movies and music. It is clean bass, but not altogether as present as I would prefer. Partly because of the open layout of my small house, but I will definitely need to get a more powerful sub in the future. At least for this room.

    Technical babble aside, I’ve been watching some older movies like the original Top Gun, Saving Private Ryan, and Jurassic Park. The bass that is present is clean and accurate. This sub definitely gives me some much needed depth I’ve been missing from my smaller Definitive Technologies bookshelf speakers. It helps to really tie in the audio side of the experience from watching movies. On the music side, I am able to set up my newer receiver to play music to the sub as well as the speakers and it fills in nicely. But there is definitely a limit to the bass here. Anything more than half way on the volume knob of the sub and it starts getting blatty and muddy in response. It doesn’t seem to want to keep up as well with music as it does with movies.

    I am thankful for this sub. It is good, it is clean, and I do enjoy it much more than it might sound like in this review. It has filled in a void I’ve been missing for a long time, especially living in apartments where I’ve been apprehensive about making neighbors angry. But since I have my own house now, and a lot of time to do the upgrades I want to, I will be investing in a much more powerful sub in the future and likely promoting this sub to an office or bedroom where it won’t need to be turned up as loud.

    Maybe I need dual SVS subs for this space. We’ll see. I’ll need to bribe my neighbors with grilled and smoked meats before making that kind of jump in bass.

  19. WarrenG –

    So glad i purchased your product! Changed the whole dynamic of my surround sound!

  20. BrianC –

    This sub is hard hitting. Running a Onkyo receiver

  21. Kumar –

    It is a good product . I am satisfied from the purchase

  22. BJ23 –

    We made 4 of these into a tv wall and we love it !!

  23. RonaldW –

    I am a ardent Polk Audio enthusiast, and this Monitor does not disappoint, the low resonance range comes through with crystal clarity.

  24. DarrelF –

    Excellent subwoofer, great sound quality. Very satisfied, this is our 2nd one purchased for use. Happy with both!

  25. ShaunF –

    If you like bass and music this is the best deal at the store. Sony is real basic and Klipsch has better audio quality but less bass and more acoustics.

  26. Jinnie2512 –

    Great sound for the price. Helps put the whole 5 point 1 sound system in perfect sound.

  27. CoreyM –

    Paired with a 7.2 ch dennon avr and its perfect. I love loud movies, sports and video games. My wife and son say its too loud so i keep it at 70% and everyone’s happy.

  28. John –

    I will never buy open box item again, the item was a 10 year old subwoofer and the wrong model.

  29. Tonton –

    Perfect for my Denon amplifier and matches my two side speakers and center speakers

  30. MyReplacementIpods –

    I LOOOOOOOOOOVE MY SPEAKER!!!!! This was the BEST PURCHASE I EVER MADE IN MY LIFE!!!!!

    This Polk 12” has surprisingly good deep bass, I’m thankful I decided to go with this purchase.

  41. MMC1 –

    Sounds good with movies and gets the job done, especially for the price.

  42. Medafaded –

    I’d give it 5 stars, but Best buy was a horrible experience. No so-called experts, just normal people trying to get by. So when i went to ask about the “Everything needed online, and all that was needed. I still had to come back to the store multiple times, and spend more money to get what was required! The bundled items online gave me mismatched brands which can cause delays, and not even the required front speakers were associated with the “everything needed”. At the store I specifically asked for an audio expert, so they can confirm I was purchasing everything i needed, he answered every thing I said with a yes! I got home did my install, and my new receiver said I was missing required Front speakers, so I had to Back to the store, luckily black friday had bookshelf speakers, same brand great price! But the sub hits great during movies, and video games, music too! Makes you really feel like you set up your own mini theater. Happy with product, glad i did my own research.

  43. Tony –

    One of the best sound system I ever bought, the base is just unbelievable! It’s a real home theater! It’s the best sound system in Best Buy right now!

  44. SamM –

    You can hear the bass when the car crashes and drums are thumping

  45. Locochico22 –

    I’ve always been impressed with the Sound Polk Audio puts out. I had to replace my Polk Sub of 20 years with this one. This one sounds just as clean with great thump for the room. Highly recommended

  46. RAppYBUd –

    I canfeel the bass throughout the house. Makes movies come to life.

  47. ReneeM –

    Sounds amazing! Easy to hook up and looks great!!!

  48. Erik –

    Good subwoofer. I like it. That is not a lot to say. it’s good

  49. Mezo –

    First this subwoofer is just for movies and some music. I have a 20×30 open living room. This woofer fills the room. Can it shake the house? Not really, but it does fill in the gap of lows that you are missing from the front channels. I got this on sale and suggest you wait for it if you can.

  50. Zipk –

    Has decent response. Sound is clean and strikes hard.
