Plasma speakers anyone with info?

There was a plasma speaker on e:Bay last summer. I believe it was called the Hall Plasmatronic. It was supposedly a complete & operating pair. I believe the reserve was between 2 & 4K. I don't think the reserve was met...
I think it was designed by Dr. David Hall. Hope this helps...

That might be the Hill Plasmatronics.
Acapella Audio of Germany incorporates "ion" tweeters
into their designs.

The name of the speaker was the Hill "Plasmatronic", and it did emit a lot of ozone as a byproduct; very hard on the lungs and other vital tissues. It was a fascinating concept speaker, but quite literally a health hazard.

While i've never heard a Plasma tweeter, i've been told by others that i trust that there are NO other options once you've experienced them first-hand. Their speed is unmatched by any type of driver based on a physical material. In specific, the Hill Plasma drivers were bone flat out to 40 KHz and remained linear out to appr 100 KHz if i remember correctly.

I know that our friend overseas ( the magical and mystical Detlof ) uses Plasma tweeters with E-stats for mids and large planars for bottom end. He's a good guy and would probably be glad to fill you in on specifics such as benefits, drawbacks, safety precautions, etc...

I can dig up a site where a guy had several hybrid dynamic / plasma speakers for sale. Some were still new in the box if i remember correctly. Drop me an email if you're interested and i'll try and hook the two of you up... Sean

Acapella audio of germany is currently producing three models with horn loaded plasma tweeters (and they've apparently figured out away around the ozone problem). This is your best bet. It may be something like acapella??.de Nelson Pass (of Pass Labs) built one back in the '70's called the Ion Cloud so he may be a source of information. I have seen one or two other units that looked to be current production models: one a japanese company and the other using TAD drivers.
