I didn't see much measured (the red line) above 100 Hz from the subs. That's usually a filter on the sub. Look back at some other sub charts and compare to yours. No you probably won't get the flat from 20-120Hz response with your setup, but you should have better than what you posted.
You don't need to mess with the Advanced page 99% of the time. Tends to introduce more problems than it solves (like trying to use the THX 80Hz figure where it's not the best choice).
I also see you set it to try lower frequencies (the blue line is flat to 20Hz) but your sub isn't even close down there. It's wasting resources trying to boost the low freq where the sub isn't performing.
The whole cutoff v/s crossover thing is different. For all but sub, it's the same, but the sub is different. Look at the crossover setting on the MRX after uploading from ARC. It's worth posting the levels settings from the MRX after uploading as well. Often the sub is too loud, and ARC has to cut it a lot (and boost other channels).
The green line is what ARC thinks tbe output will be based on the settings it send to the MRX, hence it's called calculated.
It was trying to move from red to blue, and green is how close it thinks it got.
You'd have to measure separately to see the actual result. But the lines are based on all the measured locations and most measurement tools only show one (they don't have facilities to average the 5-10 location the way ARC does).
