Focal SUB 12 DUAL — specifications and enclosures
Focal SUB 12 DUAL: T/S parameters, mounting dimensions and manufacturer enclosure recommendations. Read the original PDF and load the driver into the 3D designer.
The source lists separate coil resistance; the T/S wiring configuration must be confirmed before electrical simulation. Check the manufacturer mechanical drawing for mounting dimensions before cutting panels. No separately verified enclosure preset is included. See the manufacturer PDF; calculator proposals are not manufacturer recommendations.
Manufacturer enclosure recommendations

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.
