Basshead Supply Dual 12" 4.0V2 Ported Enclosure

4.0 cu ft net volume dual 12" ported enclosure tuned to 32 Hz delivers punchy, accurate bass for serious car-audio builds. Handcrafted in the USA, it features a carbon gray finish with zero visible exterior screws and ships pre-wired with 10ga OFC and metal binding posts for a straightforward install.

• Net Volume: 4.0 cubic feet — provides a sizable internal cavity that supports stable bass response and predictable port behavior for dual 12" drivers.
• Tuning: 32 Hz — targets strong low-end output with controlled port air flow to minimize port noise and chuffing.
• Port Area: 57.38 sq in — ample vent area to support the 32 Hz tuning without restricting air movement.
• Port Size: 13.501" x 4.25" — slot-style port dimensions engineered to achieve the target tuning within the given enclosure volume.
• Cutout: 11.125" — matches most 12" subwoofers with an 11.125" mounting hole.
• Construction: 3/4" (18mm) Russian Baltic Birch, 13-ply — rigid shell reduces panel flex for tighter bass and cleaner power handling.
• Baffle: 1" (24mm) front baffle, 17-ply — heavy, stiff mounting surface that minimizes resonance and driver movement.
• Bracing: 3/4" center baffle brace — reinforces the cabinet to maintain consistent performance under high output.
• Finish: Carbon gray stain with polyurethane topcoat — durable, showroom-worthy exterior suited for trunk installations.
• Wiring: Pre-wired 10ga OFC with metal binding post — simplifies wiring and supports robust power delivery.
• Power Rating: Up to 3500W RMS — designed to handle high-power subs without compromising enclosure integrity.
• Dimensions: Height 15.0", Width 33.0", Depth 23.0" — a substantial dual-12 enclosure that fits in many trunk configurations while remaining manageable to install.
• Handcrafted in the USA: Every enclosure is built by hand in the United States with a glue-first, airtight assembly using Titebond III for long-term durability and a clean exterior with zero visible screws.
