Speaker Lifespan


Barring a blown driver, tweeter, etc. How long before sound starts to obviously degrade? I have Mirage Bi Polars that are 12 years old. Not looking forward to replacing them.

How about Goodmans Axiom 80s
Despite their really low power handling most are still going strong after nearly 40 years-and in many ways they are still the best sounding speaker ever.
My ultralinears in the garage are still going strong. They were purchased in 1976. I had to replace the foam on the woofers 10 years ago but that's it and they still sound pretty good.

depends on designs, but I have a 1895 edison horn that still works ;) Caps change values with age,surrounds rot, paper surrounds last a long time but driver cones get brittle with age. I have had more than a few voice coils drive right through paper cones on vintage drivers.But over all a good design should last 25 years or longer with repairs. 10-15 without service.
My oldest pair is 47 years old, no repairs to drivers. Well they use fabric surrounds on the extended range "woofer" and have aluminum tweeter compression horns (they have been known to need new diaphragms at least once in a few decades, mine never did) the crossovers each lost a knob otherwise they sound fine. You name the make! BTW they have been played quite loudly.
