Mine are over 62 years old and still doing great. I did have a friend that had some surround failure on his JBL L-150's. They highly suggested to keep it out of direct light. UV is not a friend. At the very least use your speaker covers.
How long do good speakers last?
I just ordered a set of Sonus Faber Olympica Nova Vs, my first foray into nice speakers. I turn 51 this month and am hoping these will be the last speakers I ever buy. But it got me to thinking - how long should I expect these speakers to last? Or any good speakers for that matter? Does the foam eventually break down? Issues with general wear and tear? Appreciate your perspectives!
