JL Audio Dual 10" W7 Ported Enclosure

Engineered specifically for the JL Audio W7 10" subwoofer, this Dual 10" ported enclosure delivers 3.0 cubic feet of internal airspace tuned to 33 Hz for deep, controlled bass in demanding car audio builds.

• Net Volume: 3.0 cubic feet — provides ample airspace for the W7 to breathe, yielding strong low-end extension without sacrificing control.
• Tuning: 33 Hz — shapes the port resonance to emphasize deep bass response while maintaining tractability in typical vehicle cabins.
• Port Area: 42.19 sq in — a larger port cross-section reduces airflow restriction, supporting clean excursions at low frequencies.
• Port Size: 13.501" x 3.125" — port dimensions determine the effective length and air velocity for the targeted tuning.
• Cutout: 8.74" — mounting diameter required for the subwoofer, ensuring proper fitment in the enclosure opening.
• Construction: 3/4" (18mm) Russian Baltic Birch — 13-ply walls provide high stiffness and low panel resonance for tighter bass.
• Baffle: 1" (24mm) front baffle — adds rigidity at the entry point, reducing panel flex and wobble.
• Bracing: 3/4" center baffle brace — minimizes cabinet flex under heavy excursion for repeatable performance.
• Finish: Carbon gray stain with polyurethane topcoat — durable exterior that withstands daily use while preserving aesthetics.
• Wiring: Pre-wired 10ga OFC with metal binding post — simplifies installation and ensures solid, low-resistance connections.
• Power Rating: Up to 3500W RMS — supports high-power amplifiers, enabling the W7 to reach its low-frequency potential.
• Dimensions: Height 15.0", Width 30.25", Depth 19.125" — precise footprint to aid in planning fitment within trunk or cargo areas.
• Handcrafted in the USA: Built by hand with zero exterior screw holes and fully glued with Titebond III — emphasizes airtight integrity and show-quality construction.
• Ready to Install: Arrives wired and prepared for subwoofers — minimizes hardware tasks and speeds setup.
• Lead Time: Built to order; ships in 2–3 weeks — aligns with premium, custom fabrication standards.

In a real car audio build, this enclosure pairs with a JL W7 10" sub to deliver deep bass with consistent control across listening levels. The combination of a rigid Baltic Birch cabinet, precise internal volume and port tuning, and a high-current wiring pathway supports high-power, low-distortion performance while maintaining a clean, professional install finish.
