Driver Specifications
All enclosures should be made of .75” (3/4”) material only.
When possible, make the baffle 1.5” (1 1/2”) thick and
add .75” (3/4”) to the depth of the enclosure to compensate.
All volumes INCLUDE
vent/port and subwoofer displacements.
DO NOT
change the volume unless you plan on adding a sub-
stantial amount of bracing. For added performance, applying
a coat of fiberglass resin to the interior walls will greatly
improve sealing the enclosure. Adding a thin layer of poly-fill
will improve response by smoothing out enclosure reflections.
Enclosure Recommendations
When technology advances, products do as well. Does Lamborghini need to refine their cars every 2 years?
NO, they do because they can. After 6 years, it is time for a change. Say “See Ya!” to the old MOFO, and wel-
come the new MOFO-X subwoofers! The new motor is refined and increases efficiency dramatically! MOFO-X subs
use a non-pressed pulp cone for durability and smooth low bass. Like the original MOFOs, the new models use an
aluminum dustcap 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. Since the cap is aluminum and coupled to the coil former, it acts as
a heat sink or heat extractor. Using the latest materials, the new MOFO-X subs yield superior performance!
