Lansche plasma tweeter replacement every 5000 hours.

Who would purchase a speaker with a tweeter life span of 5000 hours? I was seriously thinking of picking up a pr used here on audiogon till I heard you have to purchase a new tweeter for $2000-2500 after 5000 hours. That’s ridiculous to say the least. Who knows if they will even be around in the next 5-10 years.
