Power Acoustik MOFO-124X 12” Dual 4-Ohm Subwoofer - 2,700W Max, 1,500W RMS

Get serious about low-end performance with the Power Acoustik MOFO-124X—a purpose-built 12-inch subwoofer engineered for those who demand real power and precise bass articulation. Packing 2,700 watts of peak power and 1,500 watts RMS, this dual 4-ohm beast is tuned for aggressive SPL performance without sacrificing clarity.

Engineered for Deep Bass Accuracy

At the heart of the MOFO-124X is a non-pressed pulp paper cone—a proven choice among audio purists for its natural sound reproduction. Backed with a Spruce pulp composite and topped with a polypropylene surface, the cone structure strikes a balance between durability and flexible response, making it ideal for high-pressure bass environments.

Integrated Heat Management with Cast Aluminum Fins

The signature blue anodized aluminum dust cap isn't just for looks. It's a fully functional cast aluminum heatsink that’s directly bonded to the voice coil former, pulling heat away from the core during extended play. The extended fins stiffen the cone and eliminate flex, ensuring optimal excursion and thermal stability even at high output levels.

High-Performance Suspension System

MOFO’s durable foam surround and dual poly-cotton spiders maintain linear cone travel and control, even when pushed to the limit. The sub is housed in a cast aluminum basket that resists resonance and protects internal components from distortion—ideal for both vented and sealed enclosures.

Built for Real-World Power

With its dual 4-ohm voice coils, this subwoofer offers flexible wiring configurations for 1-ohm or 4-ohm loads, perfect for monoblock amplifiers in high-current setups. Whether you're running a daily driver build or pushing the edge in competition, the MOFO 124x subwoofer delivers thunderous bass that stays clean at peak output.
