Why a Box Built for the Skar Audio VXF

Cut to the driver, not to the size

Each listing gives the cutout and mounting depth its baffle is cut to, taken from Skar's published VXF figures.

Performance Optimized
Sealed and ported cabinets solved from the Skar Audio VXF's own parameters. The dual cabinets split the air with a full-height divider, so each driver gets its own chamber.

Professional Series
Front-firing ported cabinets with a slot port, tuned for the Skar Audio VXF. The duals share one chamber and one port, so run a matched pair.

How to Choose

Size first
Pick the cabinet for the Skar Audio VXF size you own; each listing is cut for one size only.

Sealed or ported
Sealed is the smaller box and holds its output below tuning. Ported gives more output around its tuning from a larger cabinet, and every ported listing states its tuning.

Wiring
The VXF is built in dual 2 ohm and dual 4 ohm versions. Check the coil printed on your driver, match the final load to the amplifier, and run two of the same model and coil in a dual cabinet.

Every Skar Audio box
The Skar Audio subwoofer box page has every Skar Audio cabinet we cut, across all of Skar Audio's drivers.

Will It Fit?

Measure the opening
The Skar Audio VXF cabinets here run from about 15 to 45 inches wide, and every listing prints its external dimensions. Measure the narrowest point of the space, not the floor.

Behind a seat or against a seat back
The wedges rake the rear panel to sit flush against a seat back or cab wall. See every shape in the wedge collection.
