Grab a leftover Blueprint 1503 from
www.audioliquidators.com and a JBL BP1200.1 to run it. It should be enough to liquify your brain.
BTW, Audiobahn is more show than go. I've used some of their subs and have found they look better than they sound. Luckily, this was before they had an established name and I picked up the stuff for super cheap. Nowadays, they're pretty poor in the performance/$ measure. They do look really nice, tho.
