Dual Subs - looking for some guidance, please


I'm several rounds of measurement and tweaking so far, and would like some feedback on how things look on the numbers end.

I have dual subs in a 4200cf room with openings to a kitchen area. The subs are located just outside the mains. My hope is to leave them where they are, but there are other placement options if need be if I cannot get this to work well enough.

I have a BFD 1124 and am manually tweaking the REW results after doing the Optimize, etc. in an attempt to smooth out things a bit.

First, here's the measurement with the orignal settings, including some phase shifting of the subs in the processor and a xover at 80hz. (BTW fronts are B&W N804's. Subs are Velo HGS-12's.

After realizing the crossover might be important to shift down due to some nasty stuff near 50 Hz, I ended up applying these filters using a 60hz xover:

This resulted in the following curve (no smoothing)

Any suggestions on what to do from here? At this point, I think I'm over-correcting with some of these overlapping settings? No house curve has been loaded, and doesn't yet have the sound I want, but not sure what's missing. I plan to play with this during the coming week, so I'm reaching out for ideas. THANKS!
