American Bass Single 15" King Ported Enclosure

American Bass Single King 15" Ported Enclosure combines 4.5 cu ft of net airspace with a 30 Hz tuning, engineered specifically for the American Bass King 15" subwoofer to deliver deep, controlled bass in a rigid, show-ready cabinet.

• Net Volume: 4.5 cubic feet — the designed airspace that lets the King 15" breathe and extend low, reducing mid-bass compression at high-output levels.
• Tuning: 30 Hz — sets the port’s reinforcement point to emphasize deep bass while maintaining articulation in a vehicle environment.
• Port Area: 65.0 sq in — port cross-section that supports the 30 Hz tuning and smooth air movement to minimize port chuff at high output.
• Port Size: 16.0" x 4.063" — rectangular port dimensions chosen to achieve the target tuning and airflow characteristics.
• Cutout: 14.25" — openings sized to mount the King 15" sub securely with proper sealing.
• Construction: 1" Russian Baltic Birch (17 ply) with a 1" front baffle — a rigid, dense cabinet that minimizes panel flex and preserves bass clarity.
• Finish: Carbon gray stain with polyurethane topcoat — premium live-in finish that resists wear while maintaining a refined appearance.
• Wiring: Pre-wired 10ga OFC with metal binding post — simplifies wiring and provides a solid, low-resistance path from amp to sub.
• Power Rating: High power systems — designed to handle demanding amplifiers without compromising enclosure integrity.
• Dimensions: Height 18.0", Width 33.75", Depth 23.0" — footprint details for fitment in trunk or hatch spaces and enclosure placement.
