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 plywood, and hand-finished at our shop in Thousand Oaks, California.
Every box is built from 18mm or 24mm Baltic birch — panel and baffle thickness matched to the subwoofer's power handling and excursion. No MDF, 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.
