Customer Ratings & Reviews

Looking for more bass sound to go along with some Polk bookshelf speakers to downsize from my studio monitors, this one works for me. The 8 ohm compatibility and adjustable volume on the unit made it a great choice for me. (BTW, I listen to mostly classic rock and this one ROCKS !)

Have never use any Polk audio before. But very impress with this subwoofer. I think the cost of purchase was good as well.

The sub sounds great except on the high end of performance. So, when your watching Godzilla vs. Kong and this strange port noise starts overwhelming your theater experience, you do the unspeakable and TURN DOWN GAIN. I mean, can I even watch this movie now? Stupid port chuffing. How am I gonna tell my wife, "I just need different woofer".

Love the new sound from this sub woofer! Great price too!

Great sound. Nice bass that won’t break the bank!!

I was looking to replace an expensive sub with something as good but less assaulting on my wallet. Researched the Polk line and settled on this model due to the great positive reviews. They were correct! It has subtle lows that enhances the sound perfectly. I'm extremely happy with the purchase. Thanks to Best Buy for the no hassle price match. I'll certainly be back!

Excellent sound, deep base. always love the POLK sound quality

I put two of these in a 7.2 channel set up in my theater room and they can shake the house. If you want to "feel" the bass this sub will definitely do the job.

Overall, I will say this is a good sub. Just don't set your expectations too high; because even though the sub has a nice sound to it, on certain bass notes it does sound flat. On a positive note, I am quite surprise by how well the built-in 100watt amp power the subwoofer. It's hard to believe they advertise this at 50rms, should be more like 100rms how well the sub moves. You can easily push this sub too hard. I have this sub connected to a Yamaha receiver with a pair of Bose v301s.

This is a nice sub especially if your not wanting to spend a whole lot of money .

Nice size, not too big, good sound. A decent subwoofer for the money

Small but powerful enough. Basic subwoofer but solves my purpose

Great sound and excellent value. It gives a real movie theater sound

Sound just as good as more expensive ones. Easy to set up

Bought as a recommendation from an Best Buy employee !! Best decision I 've made in a while. Very versatile as far as inclusion into your set up goes. I like the idle feature that allows the amp be in standby mode until an input is received. Plus, did I mention that this thing rocks? I haven't changed the gain from the OEM setting and I'm overwhelmed!!! BUY THIS!

Purchased this at half price cause I thought mines had broken during the move but come to find out they wired my movie room incorrectly, so after trying it out I decided to keep it and run both subwoofers and it was the best decision I made concerning that room. Puts out enough bang for the buck, very happy with item. Sub is on the bottom right of the picture.

Bought this for my stereo system. Easy to hook up. Great sound .

Great quality for the price Easy to install and use

I listen the subwoofer for music (not home theater) and also own the competitive Yamaha product. The Polk PSW 108 is great addition to any surround sound system adding a fuller base dimension and complementing existing speakers. The speaker has smooth even tones and response. I don’t sense the subwoofer “kicking in” but simply supplementing the range of the system.

Looks good in living room sound great and easy to connect.
