Bass Slammer unloaded, vehicle-specific enclosures are inspired by the same technology incorporated in MTX ThunderForm enclosures. Bass Slammer enclosures are available for many of the hottest-selling vehicles on the market and are made of a high-density polyethylene resin to ensure that you don’t get any of the “ping” common in fiberglass enclosures. The resin is color-matched to the interior color options available for each vehicle.

Bass Slammer enclosures are tough as nails. They are made using rotational molding. Unlike injection molding, Bass Slammer enclosures come out of the mold with no seams, so you don’t lose any of the sonic quality of the subwoofer.

Bass Slammer enclosures are also internally braced to eliminate flexing and warping so you get the tight bass you’re looking for.
