I have a single Stephens P-52 woofer with a P-15 horn driver in a late 1940s Stephens cabinet. Still works well, and is still seeking a companion to make stereo. Otherwise, in no particular order and still working.....I have JBL C37 (D130 + 075 tweeter), 1950s, Altec 604-8G, 1970s, Dynaco A-25, 1960s, ADS 400 and 810, 1970s, (400 was refoamed, 810 are butyl), Magnepan 3.6R, early 2000s. It appears that speakers last a good while. Crossovers that use electrolytic caps should be updated.
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.
