Plasma Arc Speaker   

Plasma Arc Speaker



What is a Plasma Arc Speaker?

Plasma is a hot ionized gas that is electrically conductive. The plasma arc speaker creates a plasma arc using a high voltage electrical discharge.

When an audio signal is passed through the plasma it causes it to vibrate in sync with the audio signal. The plama in turn vibrates the air around it to create sound.


Plasma Arc Speaker

The Plasma Arc Speaker has a 3.5mm audio input jack for use with MP3 players, computers, phones, etc. and uses a 12VDC power supply, included.   ...   Read more
