Systems, methods, and devices for variable impedance audio equipment

A method for varying impedance in an audio device, comprising:

• removing a selection plug from a receiving port of the audio device, wherein the selection plug comprises a plurality of command guides configured to wire a plurality of voice coils into a plurality of wiring configurations, wherein each wiring configuration in the plurality of wiring configurations corresponds to a plug position in a plurality of plug positions, wherein the plurality of voice coils comprises at least four voice coils and the plurality of wiring configurations comprises at least three wiring configurations, and wherein the selection plug when removed is at a first plug position in the plurality of plug positions;
• and
• inserting the selection plug into the receiving port of the audio device in a second plug position in the plurality of plug positions, wherein the first plug position and the second plug position are different orientations of the selection plug;
• wherein each wiring configuration in the plurality of wiring configurations is associated with a different impedance value for the audio device.
