Ground Zero / SUBWOOFER
Ground Zero GZNW 15X-D2: T/S parameters, mounting dimensions and manufacturer enclosure recommendations. Read the original PDF and load the driver into the 3D designer.
Parameters use the linked manufacturer manual revision. One-way linear Xmax is not unambiguously confirmed; total excursion is not used as a simulation limit. Complete missing fields before full simulation. Re uses series-connected coils.
Manufacturer port: shape: slot, width: 215 mm, height: 130 mm, length: 400 mm.
Published volume and port design do not unambiguously specify Fb. F3 is not tuning frequency. Reference profile; see PDF for port details. Port dimensions are reference data, not a ready cutting plan.
Documentation only — check the limitations before use.

Data is for one subwoofer. Manufacturer recommendations are separate from CarBoxLab calculations. Net air volume excludes the driver, port and bracing; design dimensions are external. Loading a recommendation transfers the verified volume and tuning; confirm port geometry and construction separately.
