I'll also try a full sweep with the phase switch at 180
Only need to sweep from 15Hz to 200Hz when doing this since you're looking at ~80Hz area.

I tried just the sub and I get almost the exact same response
That's a bit confusing. With the sub only you should be tracking the target as shown in your first graph as the dropping line. The bass management of your receiver should be crossing the sub at 80Hz as well as your main (when set to small). Why was the sub not tracking the target?

If you have a dip at 80Hz with the just the sub playing, then it's the room and not the interaction of the sub and mains. That's fine. Sometimes once you combine the mains and sub, the phase switch will clear the problem.....
