???Modern Speakers???Life Expectancy???

The demise of my 20 year old amplifier has me thinking about this a lot lately..I have speakers that had manufacture periods starting in late 2012(Harbeth M30.1)& 2014(Dynaudio Excite X14)..Both are low hours usage & it's  likely neither is over 300-400 hours use..At 63 years old & failing health is it likely I will outlive the speakers or that I will need replacements in say the next 10 years?Is there any preventative  maintenance that will keep them fit for duty?Thanks much all.


Sorry to hear about your health sir. 
I think the odds are your speakers will be fine. I’ve had multiple 30 year old speakers and none of them had issues. 

my upstairs system is a 50yo Sansui, 30 yo Krell and 30yo Paradigms. Sounds great. Preventative maintenance would be keep them out of the sun and in a semi climate controlled environment. Other than that you’re probably good 👍. 

Good quality poly caps can last for decades...especially in a passive circuit. Inductors, resistors, and wire, even longer. Woofer surrounds can rot if they’re foam, but the butyl rubber ones last decades too.

If the tweeters have ferrofluid, that can dry up every 20-25 years or so, but can be cleaned out and refreshed.

I suppose gravity can do it’s thing to the suspension over time, so can’t hurt to rotate the woofers in the cabinet 180 degrees every 20 years or so if the speaker wire leads are long enough..

My speakers are 33YO, showing no signs of giving up.

Wish you all the best with your health.
