I appreciate the responses and Ive tried to implement some of your suggestions tonight.
Overall, I don't think I'm that impressed with the DCX2496. For some reason everytime I power the unit off I loose my settings. I saved them as an internal preset, yet have lost my settings multiple times. The interface is pretty darn kludgy and I keep loosing connection and getting random errors at synch. I connect again and the error doesn't appear etc.
The product just seems a bit outdated and kludgy to me when compared to the superslick Inuke DSP interface. I do like that I can modify it realtime and didn't realize that until one of you guys said it above. The first few nights I was making adjustments and then pushing them etc. I can definately do RTA on the omnimic so it's nice to also adjust the DCX2496 realtime. (the inuke dsp can definately do realtime too)
I ensured all the EQ was off in the DCX2496 channels like suggested by DesertDome. I put a 48dB Butterworth HP filter on at 20hz for both channels. I ensured that Channel A and Channel B were both working correctly and sounded and measured nearly identical. Output is mono for all six channels (of which I'm only using the first two). I raised the crossover on my Onkyo TX-NR1007 to 120hz for each channel and LFE to ensure the 80hz crossover I was using for the previous graphs a couple nights ago didn't get in the way of this EQ process.
Here's the result.
I've attached my new non smoothed frequency response. This FRD file is averaged over 10 captures - so it may look smoothed, but it is just multiple capture averaged.

Using the FRD file I left REW auto EQ settings pretty much as default and let it choose the target spl level. See the screenprint below for all auto settings.
These are the three EQ filters it chose. Nothing looks extraordinary.
After plugging in these three filters on both channels I get the following blue frequency response. The 48dB butterworth filter and the -12dB PEQ at 21hz really kills my 20hz performance. Not sure about that. You can see the before and after omnimic graphs.
I then droped the -12dB PEQ at 21hz to just -6dB and came up with the following graph instead to have a bit of a house curve as you recommended.
I'll listen to this for a bit and see what I think. I guess I just think that it's slightly lame that the AutoEQ isn't more perfect adept. I've spent more time playing around with this than it just takes me to throw some filters together in the Inuke DSP 3000 amp and have a darn near perfectly flat frequency response like on the Inuke 3000 DSP -- without even having any of the filters calculated automatically for me.
There is no smoothing on any of these graphs. I don't like using smoothing for measuring. When you turn on 1/6 octave smoothing the FR looks better obviously.
