How long do B&W 800 series speakers last


Hi,

I am curious to know the average life of these high end speakers particularly B&W800 series. Does the surround/ cone material give up with time due to material fatigue, dust and air corrosion etc
Does the SQ degrade.

I assume they last for like 20-30 yrs given the resale prices. I see prices dip to only 50% in 15yrs. Even less for N805's

I am sure 6-7 yrs use is very normal But what about 10-14 yr old nautilus ?
Or how about an matrix 805 treated like a baby for 20 yrs.

I've had my Matrix 802/3 since 1993 or so. I've had my Matrix 805s for about 10 years. They've lasted well all this time with no need for repairs. They may eventually need to have the caps in the crossovers replaced but they sound fine so I will wait. The only thing that has happened is that, with all of the sun they have gotten in my listening rooms over the years, there is a slight black shading to the front wood veneers right underneath the black speaker covers. Didn't know the sun could do that. That is about it.
Weird question to ask about B&W?! I thought the sound matters more than the longevity.
If you consider the life/price ratio, every High-end speakers doesn't worth the price i guess...
