Square waves contain even more power than sine waves.
All those lovely odd harmonics that ensure constant full peak-to-peak power that will cook voice-coils almost instantly. Not so much the clipping but the overloading of the voice-coils.
But then again, when some cones were made of solid polystyrene foam, the very rapid full-travel back and forth caused the voice-coil area of the foam cone to break and separate completely away from the rest of the foam cone. Had to have my B139 woofers from my KEF Concertos re-coned quite a few times back in the day.
