Let the Music Move You®

Proudly U.S.A. Made

Free Continental U.S. Delivery

Most enclosures ship free within the continental U.S., helping buyers get the right box without surprise freight costs.

USA-Built CNC Accuracy

Panels, cutouts, and ports are built around repeatable CNC accuracy, MDF construction, and fitment details that affect real bass output.

Build the Box Around the Sub, Vehicle, and Sound Goal

Every custom enclosure starts with the subwoofer, vehicle, and sound goal—not a one-size-fits-all shell. Atrend can build in MDF or birch, with material thicknesses from ¾ inch through 3 inches. Available customization capabilities include stained finishes, LED lighting, viewing windows, and painted interiors, while airspace, port tuning, baffle support, and CNC-cut fitment are planned around the build.
