Voice coils are damaged from too much heat.
The cause is too much rms power.
Clipping harmonics might add 0.5 to 1.0 watts to the treble output -- not even close to the rms power needed for damage -- and these clipping harmonics would be intermittent added treble output unless the clipping was continuous, which is rare for home audio equipment.In my opinion, the harsh sound of clipping harmonics serves as a warning to turn down the volume ... offsetting the slightly increased power output due to the clipping harmonics themselves.
A more powerful amp might sound LOUD and clean before a tweeter is damaged ... while a clipping amplifier will sound LOUD and harsh,
but the result is the same -- the tweeter is damaged.
