There are 3 variables affecting aging: 1) Materials and manufacturing quality (or lack thereof) used including glues, ferrofluids, foam surrounds, etc. which can age over time. 2) Environmental conditions including temperature and more important humidity along with potential detrimental lighting effects (UV). and 3) Damage based on usage = high SPLs that may damage driver coils and / or crossover components.
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!
