0.5 points is not negligible, it adds a lot of error to the score… glad
@amirm found and fixed the problem so we can have more accurate scores from now on
By the way
@MZKM, where did you get the data? Can I get a zipfile? I want to add it to the Loudspeaker Explorer to compare directly and maybe experiment to see if it's possible to do something about the previous measurements.
@amirm?
There is more than one difference in that measurement so it is not just the manifestation of this issue.
What exactly are the other differences / issues between the original and corrected measurements?.....
I wanted to speed up the measurements for the mic cage tests (after the review measurements were done without it) so checked the symmetrical option thinking it would half the measurement points. It did not. Instead it completely changed the density of them. This likely changes the wave expansion a bit making it better on one axis, and not so good in another. Until I run more controlled experiments, I won't know.
.....By subtracting the original Genelec data point SPL values from the corrected ones, you would arrive at a correction curve for the original measurements.....
We are talking couple of dB errors here. Any computation you make would have to know how close the mic was to the driver, the size of the driver, etc. As I said, you can just file off the tops of those little peaks and be there if you like.
I will emphasize again that we should not be so focused on small differences.
Here are correction added to all of them and think many will agree its a linear one that will benefitl all of them, by the way great thanks this new Genelec review amirn and if if you ask me
@MZKM will get some work update preference rating list for all of them
...in dirty quick calibration filtered blues animation below they are:

Animation is a 2 second toogle x3 one can see correction filter in the three missing Spinorama, 1) original review 2) amirm's new catch of Klippel hardware 3) microphone calibration added and btw
@amirm could it be for SV2 and 8341A you have active used mic calibration and then kind of forgot about it ..
...
EDIT should it be case operator had used mic calibration for SV2 and 8341A and forgot detail about it then their animation is as below, same 2 second toogle x3 of 1) original review 2) amirm's new catch of Klippel hardware 3) microphone calibration added.
