Yeah bridgman perhaps the lower M's might be good. I haven't heard them save the 22s. I constantly read reviews of monitors that have the mid bass hump and the graphs to show it. The reviewer sometimes seems puzzled as to why it sounds good. Other reviewers credit the hump.

but...when I throw in a polished and scrubbed old Miles Davis lp or my Dorati, Stravinsky firebird suite 200 gm lp, I'm in love with M60s. On the latter, the dynamics are startling and on the former, well, no such sibilance on a Miles Davis trumpet. It's stuff like that makes me want to keep the M60s. :-)
