Ground Zero GZNW 30XMAX-II — specifications and enclosures

Ground Zero GZNW 30XMAX-II: 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.

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.
