This enclosure is custom-built specifically for the Sundown Audio Xv3 18" subwoofer. At Basshead Supply, our goal with the "Branded Series" enclosures is to provide high-quality, subwoofer-specific boxes that combine excellent performance, durability, and aesthetics at an affordable price.

We use premium 1" Baltic Birch plywood throughout, resulting in an exceptionally strong yet lightweight enclosure. Our refined assembly process ensures a clean appearance—no visible screws anywhere on the box. All joints are securely bonded with Titebond III wood glue, reinforced by our solid 1" baffle and an additional 24mm baffle brace (for dual-sub models), capable of handling high-power subwoofer setups with ease.

Each enclosure is finished in an attractive carbon-gray stain topped with a protective polyurethane coat, giving your setup a distinctive look beyond generic prefab boxes. Featuring recessed satin nickel brass binding posts and prewired internally with premium OFC 10-gauge wire, these enclosures arrive ready to use.
