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.

@paradisecom I have Bozaks from 1963. Replacing the capacitors in the crossovers definitely improved the sound quality.

I just gave my brother a pair of Heresy II.   Still work and sound good.   I'm guessing they are 35-40 years old.   

After a decade goes by and as long as the cones or foams aren’t damaged you may want to think about re-capping them.

@georgemunn I am going to order the plinth. I was unaware ZU offered the Omen Def Supreme tweeters. I'll have to look those up

I believe ZU has discontinued the Omen Def Supreme. Maybe they will still build them on special order, however, they are no longer on the site. I'm a pro photographer and the site still uses a photo I took for them back in 2012. The B&W image of the omen def large driver close up. 

I have a pair of 30y/o ESL's, Acoustat Spectra 1100's that continue to impress me with each improvement in my other components. Anyone else have older ESL's?
