longevity of good speakers


i am somewhat new at the audiophile game and i am looking for some advice on speakers. NOT SUGGESTIONS. my question is in buying a high caliber speaker like the verity ovations on the used market, with average play, approx. 20 hrs./week, how long can they be expected to play at their top form? in other words, if i buy a six year old set of good speakers, how long could i realistically expect them to give me great satisfaction?

"The fluid in tweeters may dry out" -

or midrange (my Hyperions have ferrofluid damping in 6 1/2" midrange).

I believe fluid can be replaced.
