I have purchased vvx's from kevin directly and they arrived as described and work great! With that being said, they are good subs for the value, but I wouldnt jump on their new line zvx or w/e.. Better subs for the money. And to be honest I wouldnt risk sending him that kind of money and end up with b-stock or nothing at all.. If running the VVX's, its a great sub for a great price, otherwise just look elsewhere. IAD seems promising!
