SPL12D2 - 5000 Watt 12-inch Dual 2 OHM Voice Coil Subwoofer

The SPL12D2 is built for serious competition applications, delivering 2500W RMS and 5000W peak from a 12-inch platform with a dual 2-ohm voice coil configuration. Its three-layer carbon fiber cone and 418-oz magnet assembly are spec'd for high-output installs where mechanical durability and thermal headroom matter. This is a woofer designed to be pushed hard.

• Dual 3.0-inch (76.5mm) voice coils wired at 2Ω + 2Ω, allowing flexible impedance configurations for amplifier matching.
• Three-layer carbon fiber cone provides high stiffness-to-weight ratio, reducing distortion under extreme excursion.
• 418-oz magnet delivers the motor strength required to sustain output at competition power levels.
• 2-inch WideRidge surround supports controlled long-throw movement and extended cone travel.
• 2500W RMS / 5000W peak power handling suited for high-SPL and SPL competition builds.
