Excellent. And what do they tell you about the resulting frequencies on the
far side of the bridge as they relate to the speaking length LM1? And how
do they relate to transverse frequencies of the speaking lengths? No point
in any of us wasting time on this if the duplicated results are posted in
numerous places and all agree.
