DC Audio XL SPL 18" Subwoofer

Hand built in the USA, the DC Audio XL SPL 18" Subwoofer is a high-power driver designed for competition-level SPL and brutal bass control. It handles 2200W RMS (4400W peak) to deliver sustained, loud performance in premium builds—Click HERE to get a Subwoofer Box.

• Power Handling: 2200W RMS / 4400W peak — ensures the driver can sustain very high output without thermal compression or failure in demanding SPL setups.
• 8 Layer Flat Wound Hi-temp Aluminum Voice Coil: rugged, heat-tolerant coil that maintains linear motion under long, high-power bursts for consistent bass response.
• Extremely rigid non-pressed paper cone assembly: stiffness helps minimize cone flex and distortion at deep bass excursions, improving clarity in loud systems.
• Multilayered polymer foam surround: durable, controlled cone travel that supports aggressive Xmax while preserving mechanical integrity.
• Cast aluminum black frame: rigid, lightweight structure that reduces cabinet resonance and supports heavy-duty mounting.
• FEA analyzed and optimized motor assembly – Fully CNC machined: precisely engineered magnet and pole geometry for efficient motor control and consistent performance.
• Chrome spring loaded push terminals: secure, easy-to-wire connections designed for high-current applications.
• Mounting details (18" size): Mounting Depth 11.25", Outside Driver Diameter 18.5", VC Diameter 3.0" — enables accurate enclosure planning and fitment in deep-trunk builds.

In a real car audio build, this 18" XL SPL shines in high-output enclosures designed for deep, highway-filling bass. It supports a high-current amplifier setup and offers a defined sealed or ported path per recommended volumes (sealed around 3.5 ft, ported around 5.5 ft for the 18" size). With 26mm Xmax and a sensitivity around 90 dB at 1W/1m, it delivers substantial excursion and output for serious SPL ambitions while maintaining controlled bass characteristics. The dual Ohm options (.7/1/1.4/2/4) and robust construction—tinsel leads, motor boot, and CNC motor assembly—provide reliable performance under extended, demanding use.
