LOL newf! BTW, my Bose 601 Series III have multiple deep depressions in the mid-range. I gave them away to my buddy who thinks they are God's gift to audio (both his eardrums are shot from taking out wolves, bears and coyotes).

Nachos, no way the QS8 sensitivity is 98db/m/2.83V. I call BS (a misprint?) on that!

The midrange will sound much better on the M5HP and so will the sub-bass...compared to the M22 and the M3 (and maybe the M50?).
