This forum is certainly an interesting find. I've been using a BFD for sub equalization since about 2000 when I built my theater. Haven't messed with it much since the initial install, but decided it was time to get caught up on what was happening and did a Google search for BFD which led me to this site. Cool.
I have a DSP1100P.
