Interesting. I have been interested in these tweeters for years but never had the ability to hear them. Years ago I wanted to add supertweeters to my main speakers and was looking into plasma. I had no idea they had a limited number of hours. The permanently charged stat tweeters I chose work well, but it appears they have gone out of business. I have a great knack for finding gear from companies that go under. LOL. However 2 have recently been revived, TTW turntables, and the sale of Velodyne to someone actually interested in running an audio business.
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.
