DC Audio Dual 12" XL SPL Ported Enclosure

DC Audio Dual XL SPL 12" Ported Enclosure is engineered specifically for the DC Audio XL SPL 12" subwoofer, delivering deep, controlled bass through 4.0 cu ft of internal airspace tuned to 32 Hz. Handcrafted in the USA, it features a clean exterior with airtight, glue‑sealed construction designed for high‑power installations.

• Net Volume: 4.0 cubic feet — provides the internal airspace needed to extract deep bass from the XL SPL 12" in a vented enclosure.
• Tuning: 32 Hz — port tuned to emphasize low-end extension while maintaining control at higher output levels.
• Port Area: 58.12 sq in — a larger port area reduces air velocity at low frequencies, helping maintain efficiency and reduce port turbulence.
• Port Size: 14.999" x 3.875" — rectangular port dimensions that define the vent area and air flow characteristics.
• Cutout: 11.0" — corresponds to the standard 12" driver mounting diameter for the XL SPL 12" subwoofer.
• Construction: 1" (24mm) Russian Baltic Birch, 17-ply — provides stiffness and dimensional stability for accurate bass and reduced cabinet resonance.
• Front Baffle: 1" (24mm) thick — contributes to overall rigidity and sealing integrity for high‑power use.
• Center Bracing: 1" (24mm) — reinforces the cabinet to minimize flex under heavy excitation.
• Finish: Carbon gray stain with polyurethane topcoat — durable, show‑quality exterior finish.
• Wiring: Pre-wired 10ga OFC with metal binding post — simplifies installation and provides solid, low‑loss terminations.
• Power Rating: High power systems — designed to handle vigorous bass demands from powerful amplifiers without compromising enclosure integrity.
• Dimensions: Height 17.0", Width 36.0", Depth 20.5" — precise footprint to help assess fit in vehicle trunks or cargo areas.
• Build Quality: Handcrafted in the USA with zero visible exterior screw holes and fully glued with Titebond III for airtight integrity and long‑term durability; ready to install.
• Lead Time: Built to order. Ships in 2–3 weeks.

In a real car audio build, this enclosure provides the exact airspace and tuning needed for the XL SPL 12" to deliver deep bass with controlled, articulation-heavy output. The combination of a 4.0 cu ft net volume at 32 Hz, a 58.12 sq in port, and a robust Baltic Birch construction yields a stiff cabinet that resists panel flex and port turbulence under high power, while the pre-wired wiring and metal binding posts simplify installation. The show‑quality finish and screw‑free exterior deliver a clean, professional look once installed.
