Just curious, were any of your mics individually calibrated like you can get from Cross Spectrum Labs? Yes, both UMIKs have individual calibration files. The UMIK-1 from CSL has the additional calibration file they provide. So in all, there are 3 files, hmmmm, . . . . never thought about doing this before, but I'll compare the mic from CSL using both cal files. And this is the result. One UMIK-1 mic and both calibration files. One trace is the individual miniDSP cal file, and the other is using the CSL cal file. Which is better? dunno Which is more accurate? dunno Which file should I use? Well, this is interesting, at least to me. When using REW, I've always used the file that is in the folder marked "REW". That's how CSL named it. I just compared this file with a newly downloaded file from miniDSP and they are the same, so I've been using the miniDSP cal file all along when using REW, but with Dirac I've been using the CSL cal. Does that matter to me? No. It would've mattered if the traces didn't match up as close as they do.

I did send my EMM-1 as well as my ECM-40 in and got both calibrated for 0 and 90 degrees. What you see in my graphic is the original calibration curve by Emotiva as well as the calibration curve for my specific EMM-1. Regarding variance here is an article from a german company regarding an overview of 1000 measurement mics calibrated by them: www.hifi-selbstbau.de/grundlagen-mainmenu-35/softwaremesstechnik-mainmenu-66/480-1000-mikrofonkalibrierungen-eine-uebersichtEven if it is in German the pictures are easy to understand. Especially upwards of 10kHz there is quite some significant variance, so an individual calibration imho is money well spent.

Hello colleagues, I reset the xmc-1 and it already measures much better, not creating that high pass in 10khz. I even have better sound, I'll go by dirac again. Thank you all

Hello guys, as I already mentioned I solved the problem of the measurements, but now another doubt arises and that is that when I move dirac to the av in the earnings of the speakers it leaves them all at 0, I find it strange that I do not apply any gain or attenuate the speakers measuring with rew they are all at the same gain. Does the same thing happen to you? Thank you and forgive
