Speaker life depends upon the design, environment, and usage. I am not familiar with your speakers. From a design perspective, ware of the basket of driver is material dependent. Foam wares sooner than rubber as an example. The driver diaphragm is also material dependent. Metal and composites are more durable than paper. Environmental factors like heat and humidity affect materials of construction. Aggressive home playing conditions of professional playing conditions shorten life span. Crossover design with electrolytic caps may need cap replacement after 10-12 years. You should inspect these items for ware. If there are no signs of ware and your speakers sound good, don’t worry. This still appears to be a current model. So that’s comforting from a repair perspective. I have one of my first low end audiophile speakers, a 40 year old pair of DCM Time Windows still sounding as they did back then in a vaca home in VT. Do they sound as good as modern designs … no. But they have not deteriorated and sound as they did back then.
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.
