Overall, the sub looks and sounds great. For the price it is it sounds good and hits hard. I would recommend this to anyone, especially if this would be their first system. Just be sure to put at least 500 watts on this sub, if not 750. I have seen the sub take 1000 watts without a problem. And although 250 will move the sub, I would strongly recommend to go with at least 500 watts.
Pros: First, the subwoofer is very good for the price range. I was amazed at the low tones it could hit, it couldn't hit all of them but most. It is also a lot more loud on just 250 watts than I expected, my Honda CRV shakes every time it hits.
Cons: The first subwoofer I got came with the right subwoofer busted and I had to send it back, but another was quickly sent to me. The bass is a bit muddy but it was expected.
