Dynaudio C4 old stock discounted


I am in a position to buy a brand new Old stock Dynaudio C4 at a significant discount. It's been stored for at least 10 years sealed in original box under controlled environment. Is there a possibility that a speaker which has never been used could get damaged with time? Do the internal elements age without use? Could there be breakdown in the woofers and tweeters, crossover or any other component ?

I know that capacitors get old and leaky and eventually need to be replaced on aged amps. Does this not apply to speaker architecture ? 
Dynaudio’s “Guidelines for Warranty” states the warranty begins at time of purchase and lasts for two years.  So, in the event there’s an issue, you would be covered under warranty, provided the speakers are being purchased from an authorized dealer.
I was going to buy them but they're too tall for my room and the tweeters in them are a nearly 20 y o design
I’d be worried if they were 40 years old. You realize people keep audiophile electronics for 20 to 50 years right? They change hands yeah but they survive. Else what are you paying for exactly? The wood finishing?
