I am one of those unhappy costumer. So i swap to meistershaft resonator mid and back. guess what??
very annoying drone from 2000rpm to 2900rpm. i cant hear radio, not Bluetooth telephone. even more not happy??
btw, i really like your N55+evolve post, what is one of the reason i have moved to this forum.

I still have some drone with my set up as well but compared to stock drone it is nothing really, totally negligable. I had drone between 2000 to 2900 with stock and it was quite annoying, now I have around 2200 to 2400 maybe and also less present even if you stick at that particular rpm. Doesn't bother me anymore, not in the city not on the highway.
I heard Meisterschaft with mids generate drone so maybe you try putting back your stock mids to experiment?
One thing is almost for sure the N55 midpipe minimizes and in some cars eliminates the drone.
