Summary: As the review title states, I returned and exchanged a Polk 110 for a PSB 125. It's been a year and I still prefer and enjoy the PSB 125. So, no regrets. As a matter of fact, I just ordered and received a PSB 100 from Crutchfield. Been up all night auditioning it and so far I like it just as much as the PSB 125. To Polk's credit, all my car audio (speakers and amp) are Polk. So Polk gets the job done too in that respect. Guess I just prefer PSB for home audio.
Summary: I have this paired with Polk Monitor II 50 fronts, Polk CS1 II center. and Polk Monitor II 30 rears. It nudges the low end down a bit, but doesn't often add much punch. When watching action movies I'm left wondering where's the BASS I was suppose to get with a subwoofer. At a low frequency of 38Hz 3db, this thing just doesn't go low enough. I've read reviews where people pair with a Polk 70 and claim it's great.
Summary: Why buy this sub when u can get the psw 505 at the same price? It has a larger driver, more power and a lower frequency response. the 505 is not much bigger as far as size goes, but It's totally different in performance. I had a psw 10 for 2 days. It was the poorest excuse for a subwoofer I have ever seen. All you could hear was woofer flutter and excessive port noise. I returned it with intentions on buying the psw110 or the 12in. Model.
Summary: Polk should be ashamed of himself to want so much for this weak sub. Replaced it with a Paradigm PDR-8 for the same price and it blew the Polk out of the room. The Polk PSW10 sounds better and is also cheaper!
Pros: Built like a tank.
Cons: Its the weakest 100 watt sub i've ever heard!!!!
Summary: My systems consists of a Polk RM10 satellite system, a Klipsch RC10 center speaker, a Polk PSW10 subwoofer, and an Onkyo SR705 AV receiver. I'm very happy with my current setup, with the exception of wanting to upgrade my subwoofer. My Polk PSW10 has great punch in the low to low- mid ranges. (When I watch the pod race from SW Phantom Mencace, you can feel the racer engines starting, and as the ships roar by on the screen the effect is pretty incredible).
