Audio System / SUBWOOFER
Audio System H12 EVO: T/S parameters, mounting dimensions and manufacturer enclosure recommendations. Read the original PDF and load the driver into the 3D designer.
Coil connection for T/S measurements is not explicit; electrical simulation requires verified Re and Le. A mechanical excursion figure is not treated as verified one-way linear Xmax.
The published volume is not confirmed as net air volume. Check the definition in the manual.
Manufacturer volume includes the woofer and port. Deduct their actual occupied volume to obtain net air volume.
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.
