This is the prototype for a plasma arc speaker kit. Apparently it uses 60,000 volts to generate the arc and sound. If a kit does get released, put me on the list!

  1. Very nice.

    I will point out though that this is more than just a light/sound show. In addition to the sound and lightning, you probably get synchronized bursts of X-rays too….

  2. I saw an article about this a long while back (60’s) using an oxy fuel flame doped with sodium. Couple the audio to a high voltage source via a transformer.

      Thanks for the info. They do seem to produce ozone and should be used in a well ventilated area. At least that’s what I found.
