Except for the lady folks who seem to START in that range.  What
happens in so many female voices I hear (including broadcast stations)
is that high central tonality dominates to the point of overwhelming
the silibant range and 600-1200 NEEDS to be seriously suppressed to
let the silibants emerge.  I'm not sure 6 dB is enough for them.
