Are you using a miniDSP 2x4HD in this set-up? I can’t recall.
If you are then you might consider using MSO to Eq the subs. It automates filter calculations with the goal of having the same response in multiple locations. This should hopefully address the 67 to 90ish hump on the subwoofer chart.
I would also try using MSO generated filters to eq up to 160Hz to possibly help with the subs/mains overlap above the 80Hz XO.

I am using a MiniDSP2x4HD with 3 subs. I went at it again today to play with sub positioning and measurements .Today's results, I got a smoother bass response at the CLP and RLP but the LLP which is open to the stairwell and hallway always gives me trouble and the worst response. I think this is as good as its going to get until I get rid of the old sofa, chair and ottoman and get the new smaller furniture inside. It will allow me more placement options.

Todays and last weeks sub placement and orientation. The right sub is now facing the sofa instead of out into the room and the left sub is pulled closer to the left speaker.

I didnt like the measurements I was seeing and I thought I could tighten things up so I tried next day again playing with new sub positioning. Everything else stayed status quo.

Here are the measured results.
Subs 1-3 Raw response across all 3 LP
