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!

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!
Oh come on, big, you just wanted to brag about your incoming speakers. I mean who wouldn't? They are beauties to behold and I'm confident that you will cherish them for decades to come.
