Speaker Lifespan

multiply 12 by 7, then divide by 7, then subtract 0. that is the actual age of your speaker in human years. they should be fine until they dont work anymore.

I have a pair of JBL's from 1972 and no problems what so ever. Maybe the crossover caps start changing value over decades??

My speakers have followed me throughout my life, with various members of the family. My son uses my Monitor Audio MA8's circa 1990. My mother uses the first speakers I ever bought, Leak Mini sandwich's circa 1965. Mind you, she is pretty deaf now and I am not sure if she notices if sound is coming out at all, never mind deteriorating drivers.
So, a challenge, has anyone got speakers 41 years old still working. Leak, British engineering for you.

you need new speakers,then a new amp,then a new...... come on man,keep the econo goin'!!!!

It depends on the material being used, especially for the driver cone surround. Foam is (albeit musical sounding) very susceptible to rot, while rubber is more durable. I think the Xover components are not subject to degradation, because of the relatively low voltage of the signals and the low ambient temperature.
