    Best value for money, I bought these during the holiday sale for $99.99 I also purchased Sony Receiver and Speaker Set as well. All for less than $500.

    I bought the full 5.1 speaker package and amp on Black Friday sale. After I got everything setup it was amazing. The only issue I have is the bass does quite shake the room like I would prefer. I have a 7.2 capable amp so I may purchase a second and see how that goes.

    My old Panasonic Home Theater System came with a subwoofer, but it didn't have a built-in amp. This one does, and so it truly complements my Sony Receiver.

    I am still shopping for a new receiver, so until I buy a receiver I won't be able to rate this sub woofer. Most of the reviews were good and what sold me on this particular sub is the heavy rubber speaker surround rather than the foam ones, that tend to deteriorate over time.

    Purchase this sub-woofer to replace one that died. Evaluated this unit vs. others and could hear the difference and therefore could not justify spending more money for the same performance.
