Rating : - Fantastic!!!
I bought this sub, after I found out I needed a powered sub for my Sony recevier. This is my first actual home theater system and this sub completed it! It's a great buy if you mostly watch movies or play games. I haven't played music through it yet, but it should work just fine. The sub, recevier and my 42" plasma will eventually go to my room when I get a house and get my DLP, but for now it's fantastic!
