The whole Setup is in a early Stage but i think i can build an everyday usable System.
I cant explain it in English.
But here you can read how it works.
(My Setup works with another Technic but it doesnt differ too much)
Plasma/Ion tweeter
Because ionized gas is electrically charged and so can be manipulated by a variable electrical field, it's possible to use a small sphere of plasma as a tweeter. Such tweeters are called a "plasma" tweeter or "ion" tweeter. They are more complex than other tweeters (plasma generation is not required in other types), but offer the advantage that the moving 'diaphragm' is optimally low mass, and so very responsive to the signal input. These types of tweeters are not capable of high output, nor of other than very high frequency reproduction, and so are usually used at the throat of a horn structure to manage usable output levels. One disadvantage is that the plasma arc typically produces ozone, a poison gas, in small quantities as a by-product. Because of this, 1980's German made Magnat "magnasphere" speakers were banned from import to the USA. See also plasma speaker and plasma arc loudspeaker.
In the past, the dominant supplier was DuKane near St Louis in the US, who made the Ionovac; also sold in a UK variant as the Ionophane. Electro-Voice made a model for a short time under license from DuKane. These early models were finicky and required regular replacement of the cell in which the plasma was generated (the DuKane unit used a precision machined quartz cell). As a result, they were expensive units in comparison to other designs. Those who have heard the Ionovacs report that, in a sensibly designed loudspeaker system, the highs were 'airy' and very detailed, though high output wasn't possible.
In the 1980's, the Plasmatronic speaker also used a plasma tweeter, though the manufacturer did not stay in business very long and very few of these complex units were sold.
Currently there appears to be only two manufacturers still making and selling plasma tweeters, Acapella Audio Arts, in Germany[1][2] and LANSCHE AUDIO in Germany[3] This tweeter is extremely expensive, and has been favorably reviewed.[4][5][6] Note that there is at least one German DIY Audio plasma tweeter design which claims maximum sound pressure levels in excess of 115 dB, and without special machined cells, or horns, or dedicated gas tanks.[7]
