SPL12D1 - 5000 Watt 12-inch Dual 1 OHM Voice Coil Subwoofer

The SPL12D1 is built for competition-level output, delivering 2500W RMS and 5000W peak from a 12-inch platform with a dual 1-ohm voice coil configuration. Its three-layer carbon fiber cone and oversized 418 oz. magnet are engineered for high-excursion, high-SPL environments where structural integrity under sustained power is non-negotiable. This driver is suited for dedicated SPL builds requiring a low-impedance load and maximum cone control.

• Dual 3.0-inch (76.5mm) voice coils wired at 1Ω + 1Ω, allowing flexible final impedance configurations for amplifier matching.
• Three-layer carbon fiber cone provides exceptional stiffness-to-weight ratio, reducing flex and distortion at high excursion levels.
• 2500W RMS / 5000W peak power handling rated for sustained competition use.
• 418 oz. magnet assembly delivers the motor strength needed to maintain linear control at high power levels.
• 2-inch WideRidge surround supports long-throw excursion while maintaining cone alignment.
