Speakers last a very very long time especially if used carefully and not over or under driven.
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.
