There's been varied discussion on this, but here's (only...) my selection of the Threads that covered seemingly relevant issues:

There maybe some guidelines published somewhere but I have never been made aware of them. One problem is that there is such a wide range of end use applications. A pair of compression drivers being asked to reproduce 500Hz up will wear out faster than ones crossed over at 2KHz. A diaphragm in a typical audiophile's home will probably outlive him while a diaphragm in a touring sound system may only last one year.

Aluminum is widely acknowledged as wearing out faster than titanium. JBL has gone over to the exclusive use of titanium for pro (read PA ) applications. Aluminum diaphragms with mylar surrounds last much longer than all aluminum diaphragms, but there is debate as to which sound the best.

I doen`t hink there is a change in the alu diaphragm
when you drive them at home listening levels.
Checked my 24 years old 2441 and there is no change
in frequency response.
Of course i would change all PA or Disco driven diaphragms.

My GF says a diaphragm should be replaced after one use, but this seems like it would be very expensive.
