Abstract
An audio filter for use with loud speakers which substantially eliminates magnetic fields emanating from inductors of the filter by the inductors for each channel being physically oriented and electrically connected so that the magnetic fields generated by the inductors for each channel are self-cancelling. For preferred embodiments, the pair of inductors for each channel are side-by-side in close proximity to each other with current flowing in opposite directions through the coils.
