Acapella ion tweeters


Does anyone know about Acapella ion tweeters (specifically the TW1S)? I would be interested to know about the following:
1) If you have any experience with them, are they really the best out there? Are there are other tweeters which can match their speed? Are there others with similar technology?
2) Did they have ozone problems at one point or do/did all extant versions of the TW1S have it licked?
3) Are they now available separately? I remember reading in a post many moons ago that they only came as part of their speakers (I believe the mysterious Detlof was the author) but the website has a separate listing for them. And if available separately, does anyone a) have ANY idea what they might cost? and b) who in the US or Europe (or even better, Asia) might sell them?
Thanks, Travis

At an audio show years ago John Dahlquist demo-ed a system with Ionovac tweeters. Sounded very cool and open .The hotel room was also cool with the windows open to exhaust the ozone buildup..
