The new motor is refined and increases efficiency dramatically! MOFO-122X subs use a composite sandwich cone with a polypropylene surface for durability and Spruce pulp backing for smooth low bass. Like the original MOFOs, the new models still use an aluminum dust cap that couples to the voice coil former and extends over the cone. Why? The fins brace the cone and eliminate cone flex during high excursion. And since they are aluminum and couple to the dust cap and coil former, they act as a heat sink or heat extractor. Using the latest materials, the new MOFO subs yield superior performance.
