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!

I think you might be ok with those SF speakers.  My Olympica 3 are probably 7 years old and going strong.  I think 20 years is achievable.
Lol . He said I hope these speakers are my last speakers I will ever buy. In the pursuit of the sweetest sound you can achieve out of your audio equipment is a never ending story. Once your hooked it's a done deal. Enjoy the sound
Forever.  My Avalon Eclipse' are 30 years old and fine.

My dad's John B Lansing speakers were bought in 1961.  Still working fine in our living room.  They are now 60 years old, and are quite lovely endtables to boot!
