Build Quality & Design

Every Sundown Audio NSv6 15 enclosure is hand-built in the USA with precision craftsmanship. Using 1″ Baltic Birch, the enclosure provides both strength and light weight compared to MDF. Our refined assembly process eliminates all visible screw holes, while Titebond III wood glue ensures unmatched durability.

Dual-subwoofer versions feature an additional 24mm baffle brace for extreme strength. The carbon gray stain finish with polyurethane top coat gives the enclosure a sleek, unique look that stands out from generic prefab boxes. Built to withstand high-power systems, this box is the ultimate choice for serious bassheads running the Sundown NSv6 series.

Lead Time

Each enclosure is custom made to order. Standard lead time is 2–3 weeks. Please note that due to the custom nature of this product, no refunds are available once enclosures have been cut.
