I'm an opinionated person, I've heard Cerwin Vegas and were never really happy with them. You can buy different subs that are better and cheaper. And yes go with a DVC you'll be happier in the end. If you have the money and space just run 1 12" unless you don't want that much bass. If you want tight clean bass then run 2 10's. And using ported boxes is the only way heh. you get lots of DEEP bass.
