The sub has freedom to move around the room. It was only the sub on for the test. I have it crossed over at LP Freq on the sub at 130.
Make sure you disconnect your mains and set your processor to small with sub to ensure processor xover to the sub.

What I did with my f113 was place it (with my son's help) in my seating location and connected up my RS meter on a low tripod, and ran sweeps with REW. I moved the meter around until I found a location between the front speakers and the back next to my equipment rack that gave the smoothest response that followed the ideal curve. Make sure you deselect ARO, full xover without any slope, no 25Hz trim, zero phase and no polarity,...to start.

I then swapped sub/mic positions and went from there,...allot of heavy lifting later, repositioning sub, mains and even moving my seating location, and advice from brucek and others here, and it sounds fantastic! And I'm not done yet. I have a BFD1124P on order.

Your room has a cathedral ceiling, it will be a tough beast to tame bass wise, without treatments.
