MOFO-X subwoofers are refined and increase efficiency dramatically! MOFO 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 voice coil, they act as a heatsink or heat extractor. Using the latest materials, the new MOFO subs yield superior performance. Cast aluminum baskets? Of course! Increased bottom octave output? You Bet! Louder than the original design? Duh!!

Cast Aluminum Heatsink
The anodized blue dust cap on the MOFO subwoofer looks cool and also serves a specific purpose. Because the dust cap is coupled to an aluminum voice coil former, it acts as a heatsink, extracting heat away from the voice coil, keeping it cool.

Non-Pressed Pulp Cone
Ask any sound quality enthusiast what woofer cone material they prefer, and they will all say PAPER. With that in mind, we used a beefy non-pressed pulp paper cone. The aluminum dust cap fits into the recesses of the cone for additional bracing.
