Pros: Amazing bass when setup correctly with your receiver. Great price and out performs others I paid three times as much for.

Cons: Looks small compared to others I have had but outperforms them. So I would have to say I have no cons at this time...

Overall Review: I have had several setups on subs and I am very satisfied with this one. I had to work with my Yamaha receiver to get it playing right after the auto setup and make some adjustments on the sub also. But I am very impressed with it especially for the price. I would recommend it. You may have to work with settings like I did but it is well worth the money and time...
