SVS Sub measurements

Hi!
I made some measurements and wanted to ask what you think about this one?
I have:
Sony str-1080
Yamaha ns-777 towers and surrounds
Svs PB-1000 Pro
and
SVS PB-2000 Pro
I have calibrated the speakers with sony Avr and also checked the levels with rew and UMIK-1 and measured the distances after the sony calibration.
I have acoustic panels in three corners of the room from the floor to the ceiling.
My subwoofers are on front left PB-2000 Pro and back right SVS 1000 Pro.
I measured subs using towers crossed over at 90Hz.
My current measurement is the violet graph. I think the response in violet graph is kinda weird from 60Hz to 187Hz and I´m wondering should it be much flatter.
The orange measurement is previous average measurement with speakers moved slightly.
My room is average sized about W6xL6xH2,7 meters.
There is no smoothing in the rew measurements.

That response is pretty good. There is some raggedness, but the nulls there are pretty narrow. You might experiment with 70 and 80 Hz crossover frequencies to see if the global response changes for the better. It might, but it might not.

Thanks for the reply I have to try that.
I haven't played around so much with crossovers. Mostly I have played with subwoofer distance settings and speaker/subwoofer placements.
