That's the beauty of my planar-magnetic speakers, they rely on an electrostatic design and are pure resistance. No impedance means that the Hafler amps dampening factor of >200 isn't needed! They are 6-ohm, purely resistive.
You can see why the 6-ohms combined with 84db sensitivity requires a few thousand watts to wake them up.
Gotta' love them MOSFET output transistors and 140Vdc power supply rails!
Here's the theory and design info:
