You did point it very exactlyIf you mean the exact 60Hz ,ok,you're right,I didn't point it so exact.
Say 55Hz,50Hz?
No difference to me,plenty of music material there,and material that matters.
"In this graph we see over 6% at 60Hz at 86db."
which was obviously wrong.
Then you mixed up Amirs non anechoic measurements of a single loudspeaker to the statement of Neumann of a pair in half space.
By the way even 10% 2nd harmonic distortion in that low region can be inaudible, the most audible problems of 2-way loudspeakers can be seen at multitone measurements which mess up higher frequencies where audible distortion limits get lower.
