American Bass Dual 15" XFL Ported Enclosure

American Bass Dual XFL 15" Ported Enclosure is a 7.5 cubic feet ported enclosure tuned to 32 Hz, engineered specifically for the XFL 15" subwoofer to deliver deep, controlled bass in high-power builds.

• Net Volume: 7.5 cubic feet — provides the internal airspace the XFL 15" needs to move enough air for deeper bass without over constraining the woofer.
• Tuning: 32 Hz — sets the port resonance to emphasize lower bass frequencies while keeping output under control at high power.
• Port Area: 107.62 sq in — larger port area lowers airspeed for a given SPL, reducing port noise and maintaining smooth bass at high output.
• Port Size: 20.999" x 5.125" — port dimensions influence airflow and enclosure fit, matching the enclosure volume and tuning for the target sub.
• Cutout: 14.1" — corresponding woofer cutout size required for mounting with proper clearance and sealing.
• Construction: 3/4" (18mm) Russian Baltic Birch — 13-ply with a solid 1" (24mm) front baffle (17-ply) and a 3/4" center brace — delivers stiffness to minimize panel flex and coloration in bass; Bracing: 17 ply center brace.
• Finish: Carbon gray stain with polyurethane topcoat — durable, vehicle-friendly finish with clean aesthetics.
• Wiring: Pre-wired 10ga OFC with metal binding post — simplifies installation and provides a robust connection for high-power setups.
• Power Rating: Up to 3500W RMS — capability to handle high-power amplifiers when paired with the XFL 15" sub.
• Dimensions: Height 22.5", Width 40.0", Depth 21.95" — external size to plan fitment in trunk or cargo areas and mounting surfaces.
• Handcrafted in the USA: Built by hand in the United States with a show-quality exterior and careful assembly.
• Exterior details: Zero visible screw holes on the exterior; fully glued with Titebond III for airtight integrity and long-term durability; ready to install.
• Lead Time: Built to order; ships in 2-3 weeks; All sales final.

Benefits: This enclosure is designed to maximize the XFL 15" sub’s performance in a demanding system. The 7.5 cu ft volume and 32 Hz tuning yield deep, controlled bass, while the rigid Baltic Birch construction minimizes enclosure flex for cleaner low-end. Pre-wired wiring and metal binding posts simplify wiring and reliability, and the exterior zero-screw design yields a clean, professional install. With up to 3500W RMS handling, it suits high-output setups when paired with the XFL 15" sub. Built to order in the USA, it ships in 2–3 weeks and arrives ready to wire and install.
