Default speaker protection

Do you care to answer the questions I asked? Like how does a clipped amp

"pop a

voice coil"?



Overheating. Speaker design 101..check into it.


The laws of physics, primarily the first law of thermodynamics, prevent
a speaker from heating itself up without an external source. In other
words, only the power amplifier and the external ambient temperature can
assist in heating the voice coil in the absence of other forces. So,
assuming no one's driving around in a volcano, the only source to
overheat a speaker is from the amplifier. Joule's law of heating and
some other law I forget the name of describes the transduction of heat
from electricity with energy remaining constant, forming a relation
between electrical power dissipation and heat. Therefore, only an
excess of power can overheat a speaker. It seems you're in agreement
after all. But I don't know why you insist on talking about square
waves and DC, all irrelevant.





And why you think that clipping is always going to damage the

speakers?



Speakers don't like amps to give them anything but clean, raw power.
Anything else can damage the speaker.


Define "clean raw power". For instance, if I send any combination of
pure sine waves to the input of an amplifier, is it a "clean" signal?
