JL Audio Dual 13.5" W7 Ported Enclosure

Engineered specifically for the JL Audio W7 13.5" subwoofer, this Dual W7 Ported Enclosure provides 5.0 cu ft of net volume tuned to 32 Hz for deep, controlled bass.

• Net Volume: 5.0 cubic feet — Large internal airspace supports the W7’s low-end excursion with room to breathe, helping maintain bass authority at higher output.
• Tuning: 32 Hz — Sets the enclosure’s bass peak for extended low-end response while staying controllable in the vehicle environment.
• Port Area: 72.19 sq in — A substantial vent area aids low-frequency movement and helps sustain deep bass without excessive port noise.
• Port Size: 16.501" x 4.375" — Port dimensions chosen to balance airflow and tuning stability under high-power operation.
• Cutout: 11.9" — Mounting opening sized for proper fitment of the 13.5" W7 subwoofer.
• Construction: 3/4" (18mm) Russian Baltic Birch - 13 ply — Stiff, dense walls minimize flex and resonate less, sharpening bass transients.
• Baffle: Solid 1" (24mm) front baffle - 17 ply — Extra-thick, rigid front surface reduces cone-edge resonance for cleaner cone control.
• Bracing: 3/4" center baffle brace — Enhances enclosure rigidity to sustain accurate bass under demanding power.
• Finish: Carbon gray stain with polyurethane topcoat — Durable, premium-looking exterior suited for show-quality builds.
• Wiring: Pre-wired 10ga OFC with metal binding post — Simplifies installation and provides a solid current path for high-power amps.
