WHY CAR AUDIO ENTHUSIASTS CHOOSE BASSHEAD SUPPLY

We're a manufacturer, not a middleman. Every subwoofer enclosure is designed in-house, CNC-cut from premium Baltic birch or MDF, and hand-finished at our shop in Thousand Oaks, California.

Every box is built to order in your choice of material — 18mm or 24mm Baltic birch, or 3/4-inch or 1-inch triple-refined MDF — with panel and baffle thickness matched to the subwoofer's power handling and excursion. No particle board, no shortcuts. Whether you need a ported box tuned to 32 Hz for daily driving or a competition-grade enclosure with reinforced baffles, we build it right the first time.
