DS18 / SUBWOOFER
DS18 ZXI12.2D: T/S parameters, mounting dimensions and manufacturer enclosure recommendations. Read the original PDF and load the driver into the 3D designer.
The PDF lists individual coil resistance without an explicit T/S measurement connection. Verify Re before electrical simulation.
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.
