Is there ANYTHING this guy didn't think of ?
Solid-state Tesla coil.
The primary runs at its resonant frequency in the 41 KHz range, and is modulated from the control unit in order to generate the tones you hear.
It is the actual high voltage sparks that are making the noise. Every cycle of the music is a burst of sparks at 41 KHz, triggered by digital circuitry at the end of a "long" piece of fiber optics.
It's been suggested that a good name for this coil would be the "Zeusaphone".
Perhaps .... Polk TSi's ?
