Rick:
I was seriously considering a BFD as well (especially since Behringer has a $20 or $25 rebate till the end of January) but I have one concern:

Doesn't any EQ you apply with the BFD apply only to one sweet spot? Have you remeasured in different locations, or is that not applicable to your room?

I've got a square room that's giving me problems!
