I do notice that the graphs that have this high frequency drop have a more wavier line than those that don't, but that drop is still too deep to not be there with the more averaged graph with the smoother line. This leads me to believe that the M50, M2 and M22 have a diminished high end, yet mostly inaudible, but the M60, M3, M80 does not. If it's using the same drivers, I have a hard time understanding why the difference.
