Dear Cmpromo: I think that the problem that you have with that single Rel subwoofer is that you were using like a bass reinforcement not like an integrated part of your speaker system and that you only use one unit instead of two.
Please read this subwoofer links, I think that can help us to understand the whole subwoofer concept and its heavy advantages:

Btw, Sgr: you can try with your Revel subs what is on those links. It could be interesting what you could have about.
Regards and enjoy the music.
