They were done by a speaker designer I know...
Who will conduct a worthwhile listening test comparing a compensated (eq) signal to a pure one??
BTW, taken from your link:
Most people that aren't used to "accurate" bass with proper pitch and damping (long time users of vented speakers) should probably use something closer to a static Qtc of .65 or .70 or so
As Usermanual already pointed out, all things being equal, there are no psychoacoustics reasons to prefer a compromised parameter on a sound one. However, there may be plenty of psychological reasons to do so.
