A minimal inductance electrodynamic transducer having ferromagnetic shunting rings coated with a highly conductive material to increase the induced current carrying capacity of the transducer. A plurality of thin shunting rings separated by a non-conductive adhesive, attached to a pole piece connected to a magnet and/or a center pole, allows the device to operate at high power levels without saturation. The shunting rings also allow for sufficient induced current to flow in the magnetic circuit in order to oppose the magnetic field created by the voice coil.
