Nope. The type x is meant to be more of an sq(l) sub than the r and in every app I've heard has sounded much better.hmm ive never heard one so i dunno, but the type x is Alpine's "SPL" sub, i think ive heard that it still sounds good
I agree there would better choices than the x. But I'd seal if you're going strict sq w/ the x. However I'd give them much more than 600 watts.
