The CVR is a pretty decent sub for the money. They take rated power and some, which I think sacrifices the sound quality quite a bit. They get awful muddy on the low notes, but sound great with the high notes. I blew one in a week in a ported enclosure with rated power, and when I called Kicker the tech told me to under power it in a ported enclosure. Next time I will probably go another route with my set-up with maybe some Type R's which have extremely better sound quality compared to these.
