Looks interesting, though I thought that there was an easier method for dealing with eddy currents - copper-cladding the pole piece.
The shunt resistor idea sounds a bit hokey to me though. The source impedance of the amplifier does a much better job of damping the driver's motion. Easy to test: using your favorite subwoofer, turn off the amplifier and tap on the cone. Then, turn back on the amplifier, set its volume control to zero and repeat the cone-tapping test. It should sound radically different - the amplifier's source impedance is now considerably damping the cone's movement.
