Plasma Speaker Kit

 

 

As one of our most popular products, this full bandwidth Plasma Speaker was specifically designed to reproduce high quality audio through high voltage plasma modulation. In otherwords, the high voltage arcs from the Tesla Coil are modulated so that they create audio sound waves - the Tesla Coil becomes a plasma speaker. This Plasma Speaker operates at 4MHz using a state-of-the-art Class-E switching topology that creates a virtually silent output arc that permits high quality audio reproduction. This Plasma Speaker kit is one of our best demonstration pieces and its always fun to watch both children and adults jaws drop when they realize there are no speakers and that all the sound is eminating from the high voltage arc. For even more fun and better low frequency response, use two together as a stereo pair. (Please note this kit is identical to the Class-E Audio Modulated Tesla Coil Kit)

Available in both a standard and high power version. The high power version creates larger arcs and increased audio output with better low-end frequency response. Please note you will need to provide your own transformer if your electric is based on 230/240VAC 50/60Hz.
