Massive Audio / SUBWOOFER
Massive Audio SUMMO XL104: T/S parameters, mounting dimensions and manufacturer enclosure recommendations. Read the original PDF and load the driver into the 3D designer.
The manual does not define the Xmax excursion convention; Xmax is shown as reference only. T/S electrical values use the parallel-coil column. Inductance is omitted because the published magnitude/unit needs confirmation. Enclosure Qtc entries conflict with T/S values; no automatic manufacturer preset.
The published volume is not confirmed as net air volume. Check the definition in the manual.
Reference only: the manual’s Qtc values conflict with its T/S table. Confirm the design with the manufacturer before construction.
Documentation only — check the limitations before use.

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.
