ABSTRACT:
A damping circuit for speaker systems of the type containing at least one speaker having a speaker coil with an input and an output connection and having a matching coil adapted to be connected in series with the input connection of the speaker coil and a damping coil adapted to be connected in series with the output connection of the speaker coil, the matching and damping coils each having respective input and output ends, and being wound together in the same rotational direction with their respective input ends together and their respective output ends together in a method having a unity coefficient of coupling so that the primary signal current flows through both coils in the same direction, whereby electro-magnetic fields induced around the matching and damping coils interact with one another during passage of signals and damp out signal distortions due to induced transient signals in the matching coil and to reduce signal distortions due to induced transient signals in the speaker coil.
