you GOTTA mention which infinity subs ya got. there are 3 current lines of subs by infinity, with a bunch of older versions of the kappa subs. then there was the budget sub about 5 years ago that had some graphite-injected poly cone. ok, i'm goin a bit overboard here

you get the idea. also:
- will the box be ported or sealed?
- what size/tuning?
- What amp?
