lots speaker measurment diffrence(for room correction) with omnidirectional microphone and silicon ear from minidisp hear

I always thought there is something not correct in room measurment and i thought it is maybe because ears do not hear omnidirectional. so i bought the minidsp ears they named it ears (in front stand H.E.A.R.S). I do measure at same positions. the result maybe explain wy room curves have a falling slope for speakers . I was really shocked about the much diffrent result. And when i do the speaker corrections with the ears results after longer tests i always notice the correction with ears sound much more real in compare to omnidirectional microphone. the brain try to correct to a good sound, this can hear when reduce high freq and after some minutes hearing set it to neutral. then it seem highs are more less that neutral setting for some time. so it seem logical do room correction that make more linear for ears direction to sound better and not for omnidirectional microphones. omni mirophone tell me that i need only reduce 90 and 170 hz around 8 db and boost 450 hz 7 db should be good. but it sound very worse and do ear pain after longer hear. minidsp ears tell me that i have too few mids which is right and i hear this in headphone compares. increase mids (450 hz not so much as omni measure show) and reduce the 8.2 khz boost al littel at 10 khz is important and i do also on my self made fun hear eq corrections.

The reduction above 10 khz i think too is in in speakers in compare to headphones. but i am not sure if i can trust the values above 10 khz. maybe others or @amirm can try with a headphone measure system try measure a speaker. I think i need a 3d print do of my ears and put it on my omnidirectional measure microphone. :Dbut currently i am happen with the sound enhancement
the microphone and hrtf correction i do is in the minidsp ears called HPN files. this come closest what i hear. in the ears manual stand this

The HPN compensation is similar in intent to the compensation used in other published measurements. We have
also tailored it for a simplified headphone EQ target, as shown in Figure 14. Note however that for headphone
EQ we now recommend the HEQ compensation

the HEQ show the speakers have even more high boosts. thats too much mid/ high level. so correction depend on HEQ to linear sound too dull. but HPN fit very good. HPN on headphones and correct linear sound too bright. there is also a in ear curve for ears but this sound only for in ears good when correct them to linear

here is compare of measure. I measure both same distance around 70 cm and position. in omni directional is good to let look speaker FR nicer and diffrence between speaker are less.

this is kali LP6 1 and focal alpha 65 evo.
