IIRC the M22s and M60s were both designed to have the same "sound" as the M80s but in smaller enclosures (and with fewer drivers). The M2, M22, M60 and M80 are generally considered to have one "sound" (think of these as the 5-1/2" midrange family), while the M3, M40 and M50s have a slightly less "forward" sound (the "6-1/2" midrange family).

QS8s are supposed to have the same sound as M2... M80. Not sure which side of the family QS4s follow.
