There are debates on opinions that cannot be resolved. This is math and physics, not opinion.
The author of the info at the westhost link offers the relevantly titled article "Why Do Tweeters Blow When Amplifiers Distort?
" The introduction of which laments this is:
a vexing question, regularly asked and rarely answered properly. The answers are actually quite simple, but the common misconception is that the distortion creates harmonics, and the additional harmonic content destroys the tweeter.
The rest of the article then provides measurements that show the added harmonics from clipping do in fact increase the signals in the tweeter. Just that the ponderous explanation misses the point. So the author is correct: the question is rarely answered properly.
The article also makes this statement about what happens when a sine wave just below clipping is pushed 3 dB into clipping:
Peak power remains the same, since it is limited by the amplifier's power supply voltage.
Except it doesn't. The power increases even though the peak voltage
of both waveforms is limited by the power supply. As a sine wave becomes a square wave, the power ultimately doubles. Where does all that added power exist spectrally? At every harmonic above the fundamental -- many of which heat the tweeter. Edited by Roger Dressler - 2/4/13 at 9:10am
