I don't really want to get into too many details right now, but I've created a theoretically perfect transducer that converts AC signal into air compression waves with no nonlinear distortion in theory and negligible nonlinear distortion in practice.  It requires no physical dampening and the signal is pure straight off the transducer.  It has a frequency response of within 0.2dB from 20hz to 30khz.

This part is done and ready.  This transducer exists and is working.  The problem I am having is powering it.  The impedance is very, very low.  I'm talking hundredths of an Ohm--essentially a short-circuit.
HOW DO I POWER IT?!  I DID NOT START THIS TO BE STOPPED HERE.
Even if I could somehow make an amp to drive this, how in God's name would I make a cable that could transport the resulting signal?
I've solved this problem by putting transformers in the earcups, but I don't want to have to add that weight and signal degradation.

If this doesn't work out, I could always market it as a lab microphone.  It works both ways and the FR and specs are the same whether it's converting from sound to signal or signal to sound.
