"Harmonic Distortion
There is considerable discussion in the literature of nonlinear (harmonic) distortion in loudspeaker behavior [46, 47, 48]. All loudspeakers have nonlinear distortion, and small, inexpensive loudspeakers tend to have more nonlinear distortion than large, expensive loudspeakers.
Perversely, I don't think this is that important a factor in loudspeaker performance. I have measured loudspeaker harmonic distortion spectra when listening tests had suggested that it was unusually high or low [49, 50]. I have also investigated distortion when I have found a loudspeaker producing audible sub-harmonics, tones whose frequencies are an integral fraction, one half, one third, one quarter, of the fundamental [51]. In a presentation at the 1989 Audio Engineering Society Convention in New York, the mathematician Manfred Schroeder postulated that the production of subharmonics is often related to the presence of chaotic behavior in a diaphragm. This latter phenomenon can be heard on Stereophile's Test CD 2, Track 25.
But of all the loudspeakers that have been reviewed in Stereophile in the past eight years, there are only a few in which noticeable levels of harmonic distortion have been associated with negative review findings.
However, I do conjecture that listeners use overall distortion to set a comfortable playback level. If a loudspeaker has high intrinsic distortion, hence a limited dynamic range, it won't be played as loud. Once the level of harmonic distortion rises above a threshold (probably one that is different for each listener), the listener reaches for the volume-control knob. I realize, of course, that my opinions on this subject will be controversial."
