In Reply to: Distortion tests posted by Doug Schneider on June 21, 2014 at 07:59:13:
. . . D.B. Keele used to show the measured HD of EVERY speaker he tested at E-41.2 Hz and A-55 Hz. Occasionally he used B-61.7 or A-440 if he suspected problems in those areas, occasionally graphed THD vs frequency across the whole spectrum, and occasionally showed intermodulation distortion between the low E and A. I don't remember details of his testing regimen, but I do remember some speaker reviews showing up to 40% second harmonic and 53% (!) third harmonic of the low E. No way THAT won't be audible!
