FWIW; in speaker testing the most common failure mode is melting voice coil
glue. I drive every woofer to its maximum SPL capability using a ramped sine
wave ( a demanding but non-purposfully threatening) that has characteristics
similar to musical programs.

Not saying that it doesn't happen; I'd just like to know more about the
circumstance.

Yeah, in your LAB, where you don't deal with seasonal swings in
temperature and humidity. Woofers should be designed for real world
conditions, not to satisfy lab tests.
