STEG NEO X12 — specifications and enclosures
STEG NEO X12: T/S parameters, mounting dimensions and manufacturer enclosure recommendations. Read the original PDF and load the driver into the 3D designer.
Sheet covers multiple impedances without assigning T/S data. Qes and Qts are both 0.18, Qms is absent. Xmax 60 mm has no measurement convention. Ambiguous values are excluded from calculation.
Manufacturer enclosure recommendations
No ready-to-load manufacturer enclosure is documented. Load the driver parameters to calculate a CarBoxLab starting design.

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.
