Correction, (and I hope I'm correct!) 457cps is 68cents sharp, not 100cents/1/2 step. Why anyone would want that pitch is beyond me! Doesn't make sense. As for number crunching a B or D. Without actually doing it, I'd say that the Breaking strength(s) of most of the bass and upper treble would be exceeded worse than the M&H 9'/A0 Regards, Joe Garrett, RPT, (Oregon)
