Description

Black Diamond DIA-CARBON12.1D
12" High Excursion Subwoofer with Carbon Fiber Cone – 3500W RMS / 7000W Peak

The DIA-CARBON12.1D is built for monstrous low-end. With a jaw-dropping 3500W RMS and 7000W peak power handling, this 12-inch subwoofer delivers chest-rattling SPL.

Carbon-Fiber Boom
Lightweight yet unbreakable, the real carbon fiber cone and dust cap offer unmatched strength and stiffness. The 22.5mm Xmax excursion moves massive air with tight, distortion-free bass you can feel in your bones.

Engineered for Endurance
A massive 3.5" aluminum voice coil with CCAR winding maximizes heat dissipation, while the 425 oz ferrite magnet packs serious magnetic force to keep your bass clean and powerful.

Versatile Box Compatibility
Drop the DIA-CARBON12.1D into sealed enclosures (~1.3 ft³) for tight, punchy bass, or ported boxes (~2 ft³) for booming low-frequency extension. It flexes to fit your build and your sound.

Maximum Impact
With a wide frequency response from 10Hz to 200Hz and a sensitivity of 82 dB, this subwoofer brings detailed, impactful bass with minimal amplifier strain. Push your system harder without losing clarity or control.

Own the streets with Black Diamond’s DIA-CARBON12.1D!
