Hmm...nobody wants a supersub? 29mm xmax, 2500 watt powerhandling. I used around 1300 on it and it is too loud. I'm downgrading to a pair of e10o's. This sub gets very loud for a single 12. The SQ is also very good. Search up on this sub, it will hold its own with the Brahmas, XXX's, and w7's and all the other subs out there. $250+shipping is a helluva deal IMO
