From personal experience these kinds of questions only arise when someone is straining to justify a big purchase given the available budget. Sure, money management is a critical life-skill but guess what, life is short and other than passing on generational wealth, live life to your fullest. So the short answer is; loudspeakers last plenty of years-worry about your loved ones and your liver, lungs, and heart before worrying about how long your dang loudspeakers will last.
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.
