Abstract: An apparatus, system, and method is disclosed for providing auxiliary heat dissipating capacity to a loudspeaker assembly. The apparatus comprises a plug that is inserted into a vent at the back of a loudspeaker assembly and extends away therefrom. The plug makes a thermal connection with the pole piece through which the vent is bored, so that the plug conducts at one end the heat from the pole piece that is radiated thereto by the voice coil and radiates this heat to the ambient air at its other end. A plate may be affixed to it other end to provide an additional heat sink for the apparatus. The apparatus may be removable or permanently affixed to the pole piece.
