Thanks Wayne,
I have tried running only the sub, but things don't improve greatly. It, being a Klipsch RSW-10, would surely have good output in a similar sized room with halfway decent accoustics. The subs in the speakers (DefTech PT400's) are equipped with LFE inputs and have volume controls. They also had amazing output and played quite low in my old house.

The problem I would have with setting the mains to small is that I have my crossover set to 100hz because all my other speakers seem to get a little "honky" in the midrange (no doubt another result of horrendous accoustics) and the PT's sound great all over. I would also really hate to send all that upper bass to any sub. Even Xed at 80, it seems like a lot to ask of it. If I had things my way, Id like to be able to send frequencies 100hz and down to the mains, and 50hz and down to the sub. but of course I don't have the requisite electronics for that. Without getting a processor that would let me do different crossover frequencies for different speakers, I haven't been able to justify setting the mains to small. I have tried it, and there wasn't any gain that I could percieve. I would have a pretty had time essentially sawing off and throwing away the bottom half of my speakers.

Now that that's off my chest, is there a recommended prosedure for integrating speakers with good bass capabilities into a system with a sub? I would guess it would take variable phasing on every sub, right? I'd love to do that, if someone knew of a way it could be done.

But anyway, back to BFD, does anyone use it for full range EQing? Like say between an amp and preamp, or even between a specific source and the pre or receiver? Or is this something better left to high end gear?
