American Bass Dual 12" XFL Ported Enclosure

Engineered specifically for the American Bass XFL 12" subwoofer, this handcrafted Dual 12" XFL Ported Enclosure delivers 4.0 cu ft of airspace tuned to 33 Hz for deep, controlled bass. Hand-built in the USA, it features a clean exterior with zero visible screw holes and airtight joints bonded with Titebond III.

• Net Volume: 4.0 cubic feet — Provides the internal space needed for the XFL 12" to move air and produce deep bass without excessive wall resonance.
• Tuning: 33 Hz — Sets the port’s resonance to extend low-frequency output while keeping port noise under control for smooth, musical bass.
• Port Area: 57.38 sq in — A larger port area helps maintain air velocity at low frequencies, reducing chuffing and improving low-end efficiency.
• Port Size: 13.501" x 4.25" — Rectangular port dimensions chosen to achieve the specified tuning and fitment within the enclosure footprint.
• Cutout: 11.4" — Mounting hole diameter required for the XFL 12" sub in this enclosure configuration.
• Construction: 3/4" (18mm) Russian Baltic Birch – 13 ply — High-density birch provides rigidity and minimizes panel flex under high-power bass.
• Baffle: Solid 1" (24mm) front baffle – 17 ply — Extra thickness enhances structural stiffness around the mounting surface.
• Bracing: 3/4" center baffle brace — Improves enclosure rigidity and reduces unwanted panel modes during heavy bass transients.
• Finish: Carbon gray stain with polyurethane topcoat — Durable, show-quality exterior suitable for visible install areas.
• Wiring: Pre-wired 10ga OFC with metal binding post — Simplifies installation and supports high-current connections from the amplifier to the sub.
• Power Rating: Up to 3500W RMS — Ready to handle high-power XFL setups when matched with an appropriate amplifier and electrical system.
• Dimensions: Height 15.0", Width 32.75", Depth 23.0" — A footprint that fits many vehicle installations while accommodating dual 12" drivers.
• Handcrafted in the USA — Every enclosure is built by hand in the United States with a focus on airtight joints and long-term durability; exterior features zero visible screw holes and a tidy, show-quality finish.
• Lead Time: Built to order. Ships in 2-3 weeks. All sales final.
