I'm curious if anyone has gotten a chance to experience Audio Modulated Tesla Coils in real life? Or if anyone got any random comments about them, they seem pretty interesting to me :P. Yes do i realize they sound very electrical, but seems pretty neat nonetheless. I saw a comment somewhere that it sounds like sound coming out of nowhere. I wonder what kind of frequency range these things got. (vibrate the air?). Anyone got any impressions of them?
