Ground Zero / SUBWOOFER
Ground Zero GZRW 8XSPL: T/S parameters, mounting dimensions and manufacturer enclosure recommendations. Read the original PDF and load the driver into the 3D designer.
One-way linear Xmax is unverified; no excursion limit is assumed. Sd is not published in the source table. Confirm voice-coil wiring and missing simulation parameters.
Manufacturer port: shape: round, diameter: 80 mm, length: 225 mm.
Net volume and port dimensions are documented. F3 is not tuning Fb; the manual does not give Fb for this variant, so it is reference-only.
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.
