i have 2 12 CVRs...im not going to lie, the sq is not very good at all. my box is dual ported at 38 hz. It has around 1.8cf per chamber. Do i need a new box?
imo kickers are lousy in the sq department. i'd say either get a sealed box or a diff. ported box tuned lower. either way you'll lose some spl, but gain a little more sq.
