Incredible

So, first of all, I'll start out with I purchased the R3.15 about 2 years ago. I put it in the exact optimum size box in the manual and hooked it to a boss AR3000D. The crisp clear heavy bass I could believe even my serious audio buddies couldn't believe it. I'm very impressed its held up still bumps hard and clean and clear. They are now discontinued and its probably cause they are way underrated. Excellent sub I really have nothing I don't like about it.
