The typical scenario to destroy speaker high frequency 
driver in a hifi speaker is to have too low power 
amplifier and running it to severe distortion. 
The disortion causes lots of high frequency components 
to be generated by the distortion, and those high 
frequency components can overload the high freuqncy driver 
even through the total power to the speaker is much less 
than the speaker power rating. The reason for this is 
that the high freuqncy driver has typically much lower 
power rating then the other drivers on the speaker, because 
normal sounds do not have much high frequency signals.
