A heat sink for dissipating the heat generated by a loudspeaker voice coil. The heat sink comprises a multi-piece, aluminum based structure bolted together and which encompasses the speaker motor structure. In a first embodiment, the heat sink comprises a plurality of spaced apart and separate, concentric disk shaped ring members, formed in segments, each segment being fastened together. In a second embodiment, the heat sink comprises a plurality of concentric disk shaped ring members formed in segments, each segment being fastened together. In each embodiment, the assembled heat sink is positioned over the speaker motor structures. The heat sink extracts excess energy from the speaker motor structure and dissipates that energy in the form of heat into the surrounding air enabling the speaker voice coil to perform within the normal/safe operating temperature and allows for greater handling capabilities. The heat sink also increases the mechanical strength of the motor structure, increasing speaker life and ensures that the motor structure will not deform or shift maintaining the motor structure components in alignment.
