dc level 3

I just ordered 2 dc level 3 12s and they need about 1.75 cubes per driver.

I'm thinking of going ported with 1.7 cubes each (after displacement) and tuning to 32hz. Any...

2 12" dc level 3's or 1 12" RF T2D412 (new 2010 model) looking for a more SPL setup but would like some SQ aswell. dont recommend another sub these r my only options i know u will probably say DC bc its more cone area but ive seen vids of these T2's and they look like they slam pretty hard.

ok hopefully this is going to be one of my last "which is better" posts. 2 12" dc lvl 3's ~~~ or ~~~ 2 13" jl w3v3 im really looking for SPL but i would also like some SQ. plz dont recommend any other subs, i really hate it when ppl do that. if you want to recommend something, you can...

im looking at 2 12" dc lvl 3's but i wanna know like the percentage of sq to spl in a ported box. like 60% SPL and 40% SQ or whatever. also what amp would you recommend to power 2 of them thats not over like 500 but clean/powerful?
