I wouldn't worry about that area until I added the mains to the sub and did a measure to see how the overall response works out. The peak at 40Hz is a bigger concern.
Have you considered using REW to take your measurements? It's more accurate and much easier.
I would use the Auto EQ system first and then do your testing of the sub and the sub + mains after it's complete.

That initial test was run with the sub and the mains. The receivers xover is set at 80Hz. So when the signals I used were above 80, the main were producing them. I will redo the tests tonight since I recalibrated everything last night, and post the results here.
I have definately considered REW. I downloaded it and read through all of the help files. My only problem is that I do not have a good enough sound card and would have to purchase an external one to make it work. Someone very helpful, who has a BFD, told me he did all of his measurements and graphed it using excel. So, since I didnt have a proper soundcard, I did it this way.
As for the auto EQ thing. I still dont understand. I will redo my sub measurements with the mains on, with the test tones I used previously, tonight. But my question is still: Should I recalibrate the "auto EQ" afterwards? I would have to send test tones from 80Hz up to 4kHz (or something like that) as my EQ on my receiver allows me to control gains on certain freqs ( like 250Hx, 1kHZ, etc). It also has something called "trim" control. I will redo the graph and post tonight with the new results.
Thanks,
