Plasma Speakers

I thought Musical Tesla Coils where cool, but the sound quality from Plasma Speakers is so much better.





Apparently you still need a traditional subwoofer for low amplitude sounds, but Plasma arcs are brilliant for higher tone sounds. Unfortunately microphones don't seem to be able to record the audio well, I don't know if this is because they are effected by the plasma's electromagnetic field or if they just can't record higher pitched sounds.
