I'll bet you enjoy the T762. I've heard nothing but good things about it. Nothing from personal experience on the Rava. I have seen quite a few discussions at the AVS Forum (you might check over there) that indicate this is sub a lot of people like. In a 14x12 room, you won't need a monster sub and the HSU STF-2 might be a pretty good choice to get you started. Good quality, good performance, good price.
BTW, based on the room size, the pointer to the M60s or M22s is good advice. SInce you will likely move to larger digs as time goes on, I'd nudge you to the 60s.
For your own piece of mind, give Axiom a call to discuss and you might find that you can save a few $$ to put towards a sub.
