STEG / SUBWOOFER
STEG S8 — specifications and enclosures
STEG S8: T/S parameters, mounting dimensions and manufacturer enclosure recommendations. Read the original PDF and load the driver into the 3D designer.
Specification-only record. The manufacturer manual does not publish Qes, Qms, Vas, Re, Sd, Le, Xmax or frame diameter. Enclosure suggestions and full simulation require additional verified data. Nominal 8-inch size is not used as frame diameter.
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.
