What he has said is, if two speakers have the same response but one speaker has a rise of x db at a particular frequency caused by ringing, and the other is completely free from such artifacts, all you have to do is remove that 3db of output via EQ, and the two speakers will sound exactly the same, and that no one can hear the independent effects of time domain ringing outside FR in a double blind test.
If harmonics and ringing are inaudible from the fundamental frequency then a sufficiently advanced room correction software should be able to make any speakers sound exactly the same on-axis.
