I think this is different. Adidadi is running 5 small-ish speakers in a modest room. And the other chap was running very old (possibly broken large speakers and less experienced [I believe]) in a very large room.

The other chap the speakers did shutdown and these speakers did not shutdown before blowing drivers. Which to me is itself a problem idenpendent of eveything else. The Speaker should protect itself from blowing a driver.

If you think listening to music is fun, try learning an instrument.
