Are you basing this on actual observations, or on frequency 
range numbers on a datasheet?  All I'm doing with mine is 
cutting the bottom two octave bands to minimize breath 
pops, and I would do that with ANY mic. This setting was 
arrived at by critical reports from audio-conscious hams, 
and by listening to others and helping them adjust their 
TXEQ.
