Good spl and sq sub for the money, well built, push terminals.

None for the price.

These subwoofers are very good for the money. I had them in a sealed box for about a month until my system got stolen and the box wasn't even sealed very well and they pounded pretty good. The sound quality is pretty good on them, not the best by far but still alright. They are also built very well, the cone is very tough and the whole thing seems to be built to take some abuse. The push terminals make wiring it a little easier. You can underpower these things and they'll still pound pretty good.
