Eh, I'm thinking 2 XXX15's will be a bit much. And considering how much else I'd have to do to compensate for them, I'd save a good ammount going with something smaller. I'm hesitent, I don't want to be dissapointed, but what do you guys think about 2x12's? I like my music (mostly hip hop) pretty **** loud. Do you think 2 12's or 1 15" would be best? And do you think this would be loud enough (in a ported box)? I'm not about straight SPL, I'm big on good sound quality but being able to thump hard is important .
