I have a large combined family room and dining area approximately 21x30 ft with a cathedral ceiling. The total volume is roughly 7500 ft^(3). I'm looking for a subwoofer that provides a decent amount of low end for movies/TV that won't get swallowed up in that large space but doesn't break the bank. Would dual PB-2000 Pros work? I don't have a budget necessarily but trying to keep it within reason. I may wait to see if I can catch the RP-1400 SW sale at some point (would do 2 as well). I also considered a single Monolith 16.

My question is am I in the right ballpark or do I need something more for a space of that size?
