DC Audio Dual 12" Level 3 Ported Enclosure

DC Audio Dual Level 3 12" Ported Enclosure is a hand-built, 3.0 cu ft ported cabinet tuned to 33 Hz, engineered for DC Audio Level 3 12" subs. Handcrafted in the USA with airtight construction and a clean exterior, it arrives ready to install.

• Net Volume: 3.0 cubic feet — provides ample airspace for deep bass and stable port performance, helping low-end extension without overexciting the port.
• Tuning: 33 Hz — targets deep bass with a balance between output and control, ideal for larger subs in a trunk or hatch setup.
• Port Area: 43.2 sq in — influences airflow and port velocity; a larger area supports sustained low-frequency output with reduced chuffing at high levels.
• Port Size: 13.5" x 3.2" — specific port dimensions chosen to achieve the 33 Hz tuning while maintaining enclosure integrity.
• Cutout: 11.0" — cutout diameter required to mount each sub; ensures a snug, airtight seal with compatible DC Audio Level 3 12" drivers.
• Construction: 3/4" (18mm) Russian Baltic Birch — 13 ply stock provides rigidity and dimensional stability to minimize panel flex under bass pressure.
• Baffle: Front baffle 1" (24mm) thick — 17 ply, enhances structural stiffness and helps reduce panel resonance at high output.
• Bracing: 3/4" (18mm) center baffle brace — suppresses internal movement, aiding consistent port performance.
• Finish: Carbon gray stain with polyurethane topcoat — durable, showroom-ready exterior that resists wear in a vehicle environment.
• Wiring: Pre-wired 10ga OFC with metal binding post — simplifies installation and provides solid, low-resistance connections for high-power setups.
• Power Rating: Up to 3500W RMS — supports high-demand Level 3 12" subs and preserves dynamic headroom when pushed hard.
• Dimensions: Height 15.0", Width 31.5", Depth 19.0" — compact footprint with a wide stance to fit many trunk configurations while maximizing internal volume.
• Handcrafted in the USA — built by hand with attention to fit and finish for a show-quality look and durable performance.
• Exterior look: Zero visible screw holes — seamless exterior for a clean, professional appearance in any install.
• Airtight construction: Fully glued with Titebond III — ensures airtight integrity and long-term durability in a loud music environment.

In a dual-12, high-power installation, this enclosure delivers deep, controlled bass with precise port tuning and minimal flex thanks to rigid Baltic Birch construction and internal bracing. Ready to install out of the box, it ships in 2–3 weeks as a built-to-order piece designed to pair with DC Audio Level 3 12" subs.
