Can't see the first graphic. Shows broken link for some reason.
1/12 octave is pretty fine res.
Try 1/6 or even 1/3.
At 1/3 you are looking for +/-5dB across the rev range, as a good benchmark.
Even a -5dB plot can't really be heard as missing amplitude as you go down say, a walking bass line.
Bass room modes are pretty sensitive to distance from the drivers.
I can have bass boom a few feet in from the chair, and suck out in the chair!
Try to get a proper length cable, and re-measure.
I've always found with DSP room correction, less is much more.
Better to put up curtains, have thicker rug, books on shelf, even partition a wall etc etc rather than start cutting above 150Hz, or heaven forbid adding
amplitude.
'Measures flat, sounds pants', is one of my mantras
