Hi Randy,

I used to have a similar setup (DT BP2002TLs as mains, and then a separate 2x12 box sub). I played around with different EQ methods quite a bit. At one point, I even EQd my DTs as full-range mains, and each one separately for its specific location such that each speaker had a flat FR. To do that, I actually needed two BFDs. One channel each for the mains, and a third channel for the other sub. Anyway, I was able to get good results doing that, but I was also able to get good results EQing all three together as one (thereby only using one channel of one BFD). If I were you, I'd probably go that route first. If you are currently sending the LFE/sub out signal to all three via splitters already, it'll be super easy. Once you get that going, you can always go to the next step by EQing each individually or whatever. I think you'll like the result from the beginning, though. If not, the REW/BFD combo offers literally endless hours of tweaking, if you wish.

I currently use relatively full-range mains (no built-in subs, and I think they're at -1 dB at 30Hz). I allow them to run full range for stereo listening. I tweaked the BFD by hand with the help of REW to get the sub (a single IB, at this point). I simply played a 15 to 200 Hz sweep, and integrated the sub with the full-range mains by hand. My FR for music is pretty flat. For movies, I apply a crossover, and I did something similar. REW is pretty good on its own, though, and I would expect that most people will get an improved FR right off the bat by using REW's suggested filters (after measuring your FR, of course).

As to people using the BFD for full-range EQ -- I'm sure some poeple do, but it's generally not suggested because of the relatively poor specs of the BFD (the 2496 is better) and the difficulty in getting good full-range measurements. It's certainly within the technical function of the device, but most of us just use it for sub EQ duty only.
