Engineered specifically for the JL Audio W7 13.5" subwoofer, this single-port enclosure delivers optimized airspace and tuning for deep, controlled bass response. Handcrafted in the USA from 13-ply Russian Baltic Birch with a carbon gray finish and zero visible exterior screws, it pairs rigid construction with a clean, show-ready appearance for high-power installations.

• Net Volume: 2.5 cubic feet — provides the designed airspace for the W7 13.5" to achieve deep bass with controlled cone motion.
• Tuning: 32 Hz — positions the bass peak and low-end extension around typical musical content for balanced performance.
• Port Area: 35.62 sq in — larger port area supports airflow at the tuned frequency for punchier response.
• Port Size: 14.998" x 2.375" — port dimensions influence air throughput and enclosure resonance characteristics.
• Cutout: 11.9" — mounting hole diameter for the subwoofer.
• Construction: 3/4" (18mm) Russian Baltic Birch — 13-ply panels resist flex under heavy excursion for tight bass.
• Baffle: Solid 1" (24mm) front baffle — 17-ply adds stiffness where the woofer loads the box.
