Soix rcommended what I would have, two SVS SB-1000 Pros. I own two different REL subs and both are great but more subs is better if they are good quality. Read up on distributed bass array and I'll say, it works.
I now have two SB-2000s and one SB-3000 (all sealed SVS) at 50Hz and 40Hz, and those three are much better than my single, very good REL sub was. I want a fourth... Good luck!
