Ground Zero / SUBWOOFER
Ground Zero GZNW 38NEO-SPL — specifications and enclosures
Ground Zero GZNW 38NEO-SPL: 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 follows the published table; confirm the T/S measurement coil wiring. No ready enclosure profile: the manual does not give an unambiguous automatically applicable recommendation.
Manufacturer enclosure recommendations
No ready-to-load manufacturer enclosure is documented. Load the driver parameters to calculate a CarBoxLab starting design.

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.
