If you'd like to fix it, here is what I would try:
Using channel 3, measure cc with subs on, cc with subs off, then subs on with cc unplugged. The first measurement should show the dip you mentioned. The second two measuremts show how your subs measure and your cc measures before they combine to give you your very first measurement of cc+subs. These measuremts correlate to whatever distance/delay setting you have set in your avr.
Now Increase/decrease your sub distance/delay by 1' measuring cc+sub each time. Once you have a bunch of measuremts, you can go to the All SPL tab and unchecked everything except the first three measurements above. Then systematically check and unchecked the incremented/decremented cc+sub measurements noting which ones a "above" your initial three measurements. If any part of a measurement dips below your original three, it can be deleted, it's not constructive. Pick the best one and set your avr to the setting in the distance/delay setting.
Alternatively you can do this with your mains of you focus more on music.
As I mentioned, subwoofer alone is flat up to 100 Hz and then has a dip in response. I already did a sub tweak and made overall transition much better, but that 100-105 Hz issue still persists. (crossover at 80, looks worse everywhere else)
However, regardless of that...I have to re-run Audyssey again, because last time I mistakenly ran it without reseting some subwoofer settings and that might've actually worsen the calibration. But still, that won't rid me of that dip.
