Thanks for following up with graphs. I am not an acoustics expert, and I hope that others who are will answer. But I'll give some tentative ideas based on my experience with acoustics and EQ in my various systems.
I realized after staring at them for a while that I'm not the best one to interpret graphs #2 and #3, but looking at #1, there are two things that might bother me.
The excess bass around 80 and 160 Hz is one. I like a little bass boost, but more than 10 dB seems a lot. These are probably room effects.
The other issue (taking the heavy purple line as an average) is the rising FR from 1k to 3k and approximately 8 dB shelf down thereafter. I don't know if the HF response could be made more even by adjusting toe-in of the speakers, or not. I would guess the 3 kHz peak might make music more immediate, but more tiring on some material. However, the lowered treble level might counteract that somewhat.
The big question is, how does it sound to you? If you like the result, that's the main thing. And I hope others will have something to say, too.
