My intention is to remove the 2.5kHz part of the sound power peak at 3.2kHz without hurting the direct sound to much compared to the original tuning.
Compared to the auto EQ yes I want to lower the direct sound peak and get a slight dip at 2.5kHz since it sounds much less harsh and is more enjoyable with most speaker of such kind.
Ah, I think I got it.
Besides all that extra fine surgical anechoic EQ, ~1 db reduction at 3.2 kHz is what you really think makes the biggest difference in reducing mid-HF "harshness" of this speaker.
Eh, color me skeptical... I mean, seriously, you got to be kidding me.

It appears I didn't even bother EQing out that minuscule upper mid peak. Although, I did cut out some of the bass port resonance (~1.6 kHz) that seems to be leaking out (and just happens to be oddly emphasized) in my own nearfield in-room measurements as shown above.
