...Yes, and so do actives. There are actives out there that are multiple decades old (30+ years) and they still work fine.
OK then, please name one active speaker that has been operating for 50 years or more. This is not hard to do with passive speakers, as that list is a long one.
I can tell you that I have had three (3) active subs not make it much past the 5 year mark before the plate amp failed, and they were all from good reputable companies that just no longer stocked replacement plate amps for what was now in their eyes a discontinued product. Since there is zero standardization of plate amp dimensions and hole patterns, all three (3) of those not very old subs was headed for the landfill - until I decided to use my sheet metal working capabilities to make adapter plates to mount replacement plate amps sourced from Parts Express. That was when I learned that one of the plate amps also took out its woofer when it failed, so I had to also source a replacement woofer as well. None of those subs was abused. I think two of the three failed in the Auto-Turn-On sensing circuitry - which I could not reverse engineer and repair because of conformal goo that had been painted on the printed circuit board. Next time won't be such an easy replacement as the wood byproduct cabinets (particle board/mdf) now have lots of holes and silicone sealant all over them. BTW, I bought replacement plate amps with manual on/off switches.
Even if a regular power amplifier fails, which I personally have found much less likely, you just slide another power amplifier onto the shelf in its place, and connect the standardized connectors from the last one to the next one. Then if you like you download the service manual for the failed one and repair it, and have a spare without missing a beat.
