I have a pair 25 year old Wharfedale Diamonds. I had to do a little glue repair on the dust caps. The tweeters look like ones you could replace for $6 bucks- for the pair! No one can believe how good they sound.
Foam deteriorates, some people replace caps, but old cared for speakers should last a long long time.
