It all depends on how the speakers were constructed and the materials used. Cones with foam surrounds deteriorate in a few years and need repair. Quality speakers with long-lasting materials are a different story. My woofers were made in 1946. That’s not a typo. They will turn 80 next year. And they sound fantastic.
How long should high quality speakers last?
My Zu Omen Def MKii (rev B) are going on 13-14 years old. The speakers sound wonderful. I have no intention of parting with them. The speakers came with the latest ZU tweeter design. How long should I expect the speakers to last without any issues? I do not abuse the speakers and run them with my Luxman 595ase amp.
