MOFO-104X | 2400W 10 Inch Dual 4 Ω RMS Subwoofer

Power Acoustik MOFO‑104X – 10″ Dual 4Ω Subwoofer - 2400W Peak / 1200W RMS

The Power Acoustik MOFO‑104X represents a redesigned force in high-output subwoofers, fine-tuned for strength, thermal control, and clean low-end delivery. Part of the MOFO Series X, this 10″ dual 4-ohm subwoofer delivers 1200 watts RMS with a build engineered for real-world SPL and reliability.

What separates the MOFO‑104X from other 10" subs isn’t just power—it’s the way that power is controlled, cooled, and translated into accurate, deep bass. This driver is built around a composite sandwich cone that combines a polypropylene face for stiffness and a spruce pulp backing for warmth and responsiveness. This hybrid design reduces flex while preserving low-frequency articulation.

Power & Coil Architecture

At the core is a 2.5″ dual 4Ω voice coil, wound on a lightweight aluminum former and supported by a cast aluminum basket for structural rigidity and non-resonant operation. Rated at 2400 watts peak and 1200 watts RMS, the MOFO‑104X maintains consistent output across extended sessions without thermal sag.

• Power Handling: 2400W Peak / 1200W RMS
• Voice Coil: 2.5″, dual 4Ω, 4-layer on aluminum former
• Sensitivity: 83.4 dB
• Frequency Response: Fs ≈ 29.6 Hz
• Xmax: 15mm

Thermal Control: Functional Fins & Heatsink Dust Cap

The anodized blue aluminum dust cap isn’t a visual gimmick. It’s directly bonded to the voice coil former, doubling as a functional heatsink. Extended fins across the cap brace the cone during excursion and draw heat away from the coil, improving power handling and reducing distortion during heavy bass drops.

This heat-transfer architecture yields increased output, reduced risk of burnout, and enhanced thermal stability, particularly in ported enclosures and high-SPL applications.

Cone, Suspension, and Build Details

Built for those who prefer the natural sonic behavior of paper, the MOFO-104X features a non-pressed pulp cone reinforced with composite layering to prevent flex without compromising tone. The dual poly-cotton spider suspension allows for precise cone control during high excursion, keeping movement linear even under pressure.
