Aluminum Voice Coil Former The voice coil former is black, anodized aluminum for highly efficient thermal transfer. This allows winding high temperature copper wire in multiple layers for improved efficiency. THE RESULT: Improves power handling by efficiently dissipating heat Four-Layer Voice Coil Multiple layers of high temperature copper wire are wound on the Aluminum Voice Coil for efficient thermal transfer.
