These are pretty tight..
I got to hear Mikes when he cane through and i was really, really impressed with the single 12 setup, in a decent box. Box was tuned in the low 30's i believe, and this sub was bangin. It hold's its own pretty nice on the chopped and screwed music, but it aldo kept up real nice with the kicks frm some fast paced rock song that i cant remember what it was called right now.
All in all, well worth the asking price, and i think i might have to trade up for a 15, because i really like the way they look
Peace
