Speakers don't blow up because of "amplified distortion which causes the speaker piston movement to become non linear" but rather clipping allows power to defeat the crossover point and burn the fine coil and leads, similar but different to how a diode only allows power to continuously flow in one direction but will allow pulsed transients to flow in the opposite direction. This illustrates the "minor exception" factor.
Drivers exploding on the other hand usual do so if they are of a high hardness material and resonance node is excited at high power, or if their excursion is exceeded and the air load or suspension puts the diaphragm under additional stress. The T&P drivers all have notable resonance nodes as dictated by the material though they are mostly outside their intended crossover range. The amplifier may have been responsible possibly too.
