My Altec's with cloth surrounds are original from late 60's or early 70's, I prefer treated cloth surrounds to even butyl rubber. For foam surrounds, I use mink oil about once every 2 years to keep them pliable.
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!
