Massive Audio / SUBWOOFER
Massive Audio GTX 122: T/S parameters, mounting dimensions and manufacturer enclosure recommendations. Read the original PDF and load the driver into the 3D designer.
The manual does not define the Xmax excursion convention; Xmax is shown as reference only. Electrical parameters use the parallel-coil column. Manufacturer box dimensions include displacement; listed volumes are retained as reference, without assuming net volume.
The published volume is not confirmed as net air volume. Check the definition in the manual.
Reference recommendation: confirm net air volume after driver, port and bracing displacement before applying.
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.
