Well, I have a few more places to check, but I haven't had the time lately, and while they are both very large dips, they are also very narrow, and aren't as noticable as you might think. One is at 45hz and the other's at 56hz. Just to give you an idea, at 40, 50 and 60 hz, the response is all back to normal, and is actually pretty straight other than these 2 dips. I'm going to start working on my house curve this weekend, and I'm going to try giving each of these a narrow boost of at least a few dbs. Did you add dbs anywhere, or mostly just drop some and move the sub around? In my last place, I found that worked much much better (as most people on these boards reccommend), although the dips were much wider.
I have a 2 boosts and 6 cuts. The 1 boost was narrow and was necessary only because of the cuts on either side of it. The other boost is in that big dip you see, and contrary to the advice I also receive it did help. It was the last thing I tried and I think I boosted +4 dB between 50 and 60 Hz somewhere. You'll notice that my pink curve still shares a lot of movement in the same general areas as the blue curve with the biggest exception being around 50 Hz, I think that's where the one troublesome boost was required.

I ended up increasing the sub level by several dB's from my pre-BFD setting. Once I started cutting frequencies, I noticed my average response was well below my speaker's reference level of 65 dB or so. I think my sub's gain knob is around the 12 o'clock position now instead of the 10 o'clock it was at. I also boosted the receiver gain to the sub when following the BFD comprehensive setup guide.

Hmmm, this site has everything you need to know about the BFD and links to test-tones.
