STEG / SUBWOOFER
STEG SS-10 (4 + 4 Ω, manufacturer sheet) — specifications and enclosures
STEG SS-10 (4 + 4 Ω, manufacturer sheet): T/S parameters, mounting dimensions and manufacturer enclosure recommendations. Read the original PDF and load the driver into the 3D designer.
4 + 4 ohm variant from the manufacturer sheet. Qes calculated from published Qts 0.35 and Qms 7.18: Qes = Qts × Qms / (Qms − Qts) = 0.3679356; derived, not directly published. Mounting depth 128.7 mm read from the mounting-plane dimension in the manufacturer drawing; flange height is separately 5.7 mm. Re/Le remain blank because T/S coil wiring is unconfirmed. Xmax 22 mm peak-to-peak = 11 mm one-way. The power row prints a 1500 Hz high-pass condition; it is not an unconditional sub-bass power rating. Verify before use.
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.
