Well there's a bunch of box builders on here that could be a big help. Rockford, Kicker, JL, etc. have their factory preferences for their subs and a lot people don't really find them optimal for the goals they wanted out of the sub. With 2 T2's I'd imagine your goals are mainly SPL. Without looking at the factory specs I'm going to guess RF is about 1.75-2.00 cubes a woofer. Whereas I'd probably give em' 2.5 cubes a pc. and tuned low (around 30-34 hz). My suggestion is get a hold of a designer, tell them what your goals are their and they'll steer you where you need to go.

I had one t212 in a 2ft ported at 33hrtz, and it hummed sweetly. Take up alot of space. You might be able to get by with less than 2cft per. But why choke them out. If you have the space, go with atleast that 2cuft per. If not, the 1 twelve in that space on about 1k was crazy, i would've loved to have two of them with 1k per. ssteele18 built mine, check with him, very helpful with the box he did for me.
