You may have described the audible signs of "clipping" Perhaps your full 
steam is a few two many pounds over pressure for the boiler!
Essentially clipping produces square waves, initially only on the highest 
"peaks", but as the overload increases in severity, the impact of the 
clipping becomes clearly audible. During the "is it or isn't it" stage -
the 
amp is still producing an increased spectrum of high frequencies, which 
MIGHT be a worry to a marginally rated tweeter / crossover, but  severe 
clipping probably "takes out" the crossover / tweeter as well as 
significantly increasing the power dissipated in the woofer. In addition 
the effectiveness of it's voice coil cooling will be compromised -
spending 
time stopped at both extremities.

My guess would be you killed them Judging the onset of clipping is an art 
depending on the music source material.

Good luck
