DC Audio Dual 10" Level 4 Ported Enclosure

DC Audio Dual 10" Level 4 Ported Enclosure is a handcrafted ported enclosure engineered specifically for the DC Audio Level 4 10" subwoofer, delivering deep, controlled bass with 2.3 cubic feet of airspace tuned to 34 Hz.

• Net Volume: 2.3 cubic feet — Defines the air space the woofer uses; in a ported design it influences low-end extension and how hard the driver can work before port effects become noticeable.
• Tuning: 34 Hz — Sets the frequency where the port adds boost; lower tuning generally yields deeper bass extension while demanding more precise alignment with the driver’s excursion.
• Port Area: 33.06 sq in — Larger port area aids air movement at high power, helping maintain audible bass without port chuffing at the tuned frequency.
• Port Size: 11.499" x 2.875" — Physical dimensions that determine air tuning and internal routing; compatible with the enclosure’s 34 Hz alignment.
• Cutout: 9.35" — Mounting opening needed for 10" drivers; confirms standard 10" sub compatibility.
• Construction: 3/4" (18mm) Russian Baltic Birch – 13 ply — High stiffness and low recursion of panel flex improve overall enclosure rigidity and transient response.
• Baffle: 1" (24mm) front baffle – 17 ply — Thick, solid front surface reduces panel resonance for cleaner bass articulation.
• Bracing: 3/4" center baffle brace — Adds structural support to minimize internal vibration and maintain enclosure integrity under heavy excursion.
• Finish: Carbon gray stain with polyurethane topcoat — Durable outer layer with a refined look suitable for show-quality installs.
• Wiring: Pre-wired 10ga OFC with metal binding post — Simplifies wiring and maintains solid conductor pathways for high-current demand.
• Power Rating: Up to 3500W RMS — Indicates compatibility with high-power amplifiers and dynamic peak demands without over-stressing the enclosure.
• Dimensions: Height 13.0", Width 29.875", Depth 18.5" — Size cues to fit trunks or rear decks in a variety of vehicles.
• Handcrafted in the USA — Built by hand with a show-quality exterior; emphasizes craftsmanship and local production.
• Exterior Assembly: Zero visible screw holes; fully glued with Titebond III for airtight integrity and long-term durability.
• Lead Time: Built to order; Ships in 2-3 weeks; All sales final.

In a real car audio build, this enclosure suits high-power 10" subwoofers needing a rigid, precisely tuned ported box. The combination of Baltic Birch construction, a heavy front baffle, and reinforced bracing minimizes unwanted flex and resonance, while the pre-wired hardware and clean exterior simplify install and finish aesthetics. Its 2.3 cu ft at 34 Hz provides deep bass with controlled articulation, making it a strong choice for trunk or rear-deck installations requiring serious low-end performance.
