Room correction: strange curve

[faustocat]

This is the correction curve for my room using a dayton imm6 mic. It sounds great, but what I can't understand is that 55hz are enhanced and lowered AT THE SAME TIME, although applying very different Qs. I've repeated the measurement many times, but the result is more or less the same. Without the RC feature, I'd never have been able to get such a weird and good sounding curve
Just need a little fine tining to lower the peaks a bit.

Well then maybe first a question here:
Are the speakers able to go down to 55Hz? Because usually there is rather too mich bass due to room modes here…

Filter 2 is probably simply an over correction! Try removing it (and if necessary ajust the gain down in Filter 1) it will probably sound the same.
Or try using the smoothing filter (from 1/6 to 1/3)

Speakers are absolutely capable to go down to 55hz, they are b&w towers. I don't know if filter 2 is an overcorrection, certainly the midbass sounds less muddy now, and the mids and low trebles really shine. I'll try your suggestion anyway. Thanks a lot!
