How long do high quality speakers "last"


I am the original owner of a pair of ProAc Response 2 speakers. They are almost 7 years old, but have never been driven excessively hard. How long (i.e. useful lifespan in years) can I expect these speakers to "last" (i.e. no significant sonic degradation) if I care for them carefully? When they do start to degrade, what mechanical failures and sonic degradations can I expect to occur? Thanks in advance!!!

Quality speakers are made to quality standards and can last for decades.

I have a pristine pair of ADS L-520's that I bought new in 1980.  They are currently used in a secondary system.  They have been well taken care of, not exposed to temperatures extremes, driven with only quality electronics and their woofers use butyl rubber surrounds that will last forever.  So I see no reason that I can't get another 36 years out of them.
