PowerBass PBX1-8D4 — specifications and enclosures
PowerBass PBX1-8D4: T/S parameters, mounting dimensions and manufacturer enclosure recommendations. Read the original PDF and load the driver into the 3D designer.
Test impedance is not explicitly identified as DC resistance; Re is left blank. Confirm coil wiring and electrical parameters before power simulation. No separately verified enclosure preset is included. See the manufacturer PDF; calculator proposals are not manufacturer recommendations.
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.
