I purchased this Subwoofer because I just purchased a new Sony STR-DH590 and it had the option of adding a second subwoofer to balance out the Bass sound across my living room.I am still having problems setting up the amp so that I am getting better treble and the higher pitch sounds from guitar's...

I have 2 of these in a 5.1.2 home theater setup. They sound OK. Worth it for the sale price. My 10 year old paradigm 10 subwoofer sounded better at low to mid volume. Biggest annoyance is when at lower volumes, sub constantly turns of with a loud CLICK until enough bass is signal is detected to to...

Bought this to replace an old 12 inch sony that had stopped working. Smaller in size but way bigger sound. Couldn't be happier with this. Sound quality is great but I am not an audiophile. Working in a 7.1 system.

Needed to replace an older Sony subwoofer of 19 years Sony subwoofers is a great value for what I need. May even buy a twin to this one. My receiver supports two subs.

Got this to fill in the lowest of the low frequencies with a pair of vintage KEF bookshelf reference monitors with a new Rotel integrated amp. Now our system sounds like DisneylandI put on the soundtrack from the Fantasmic show, and I can feel it just like I was at the show.

To appease my wife I needed a small subwoofer to compliment a smaller pair of vintage ADS speakers in our condo living area. The Sony 10" woofer was a good solution for me. It fits right where I need it (laying on its side) and fills in sonically from 35-75Hz nicely where the smaller speakers don't.

I was looking for an a smaller sub to complement a new pair of KEF Q100s. This fit the bill perfectly - great sound, small size and affordable price.

I've had Sony products in my car and home for years and never a single issue. This sub compliments my 5.1 setup perfectly and I expect the same level of quality as all other Sony products I own.

I love the build for the asking price, but still the build quality could have been improved! Buttons, switches and the body could have made with more sturdy materials as Sony was synonymous for quality once.
