How long does it take a decent quality speaker to "wear out"?

Totem Acoustic Speakers are made to last a lifetime. In addition they are designed to sound identical in any part of the world they are domiciled. They are absent of any wool or Acoustic filling that breaks down over time.

Good question!

Other than the driver surrounds crumbling, I have never had a speaker “Wear out” I have upgraded crossovers because it was an upgrade, not because of any other reasons.

Correction,  I did have to replace a tweeter, but that was probably my fault. 😀

I had to have the foam surrounds of my WATT/Puppy Puppies replaced after about 20 years.

Long time ago, I blew out the midrange of a Rectilinear III Highboy doing stereo wars in a dorm.  Duh.

Gradient 1.3 speakers still playing them after 27 years. I been thinking about buying a new pair of speakers,  like the Raven celesti speaker ,any opinions , I know they have 45 day trial, Like do they sound very clear on top,  like horns .I have read 2 Audiogon reviews and pt audio, and Steve Huff. My speaker are not box speakers, If this helps ,thanks,,,
