ESX / SUBWOOFER
ESX QXS8D4: T/S parameters, mounting dimensions and manufacturer enclosure recommendations. Read the original PDF and load the driver into the 3D designer.
The sheet lists resistance separately for each voice coil without explicitly identifying T/S wiring. Re and Le are not imported into the electrical simulation until wiring is verified.
Tuning Fb: 39.0 Hz.
Manufacturer port: shape: round, diameter: 70.0 mm, length: 310.0 mm, count: 1.
The published volume is not confirmed as net air volume. Check the definition in the manual.
Reference recommendation: the source does not establish net air volume after occupied volumes are deducted. Confirm before applying.

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.
