Thor's Hammer is great, and is no doubt on the very short list of cost-no-object subs. But if cost is an object, it's $21K without crossover or amplification. By contrast, the top of the line JL Gotham, with two 13.5" drivers, is $12K complete with crossover, amplification, and some room optimization EQ. Two of them cost less than one Hammer plus the required amp and crossover. Anechoically, a Gotham is down about 6 dB at 16 Hz, so I suspect that two of them with boundary reinforcement would do just fine.
At the OP's price range, you'd be hard-pressed to beat his choice of two: the DD12+ or F113. They're both so good it comes down to personal preference. JLs are incredibly fast and integrate well with main speakers, but the DD+ series has more sophisticated room-blending EQ circuitry (from what I've read). I've heard JLs and love 'em.
