MOFO-154X | 3000W 15-Inch Dual 4-Ohm VC Pro Subwoofer

Power Acoustik MOFO‑154X 15″ Subwoofer — Built for Bass Without Boundaries

The Power Acoustik MOFO‑154X is not your average subwoofer. Designed with SPL-focused performance, this 15-inch beast handles 3,000 watts max and 1,700 watts RMS with ease, built to deliver deep, low-frequency output without mechanical fatigue or thermal breakdown.

This model represents a precise balance between brute force and refined acoustics. Every component of the MOFO-Series X has been engineered to handle demanding car audio systems, especially in ported enclosures between 3–4 ft³, where deep bass extension and loudness are mission-critical.

Engineered for High SPL & Thermal Stability

At its core, the MOFO‑154X runs a 2.5″ dual 4-ohm voice coil with 4-layer winding and a 373 oz. motor volume—a configuration designed to push massive air while minimizing coil fatigue. The result? Substantial bass output, even under extended sessions at high volume.

Composite Cone with Structural Damping

The cone assembly fuses a polypropylene exterior layer with a non-pressed spruce pulp core, giving it the flexibility and acoustic absorption properties that optimize both bass response and cone stability. This structure reduces unwanted resonance, enabling cleaner low-end frequencies and tighter control under high excursion.

Integrated Heatsink: The Blue Dust Cap Advantage

The anodized aluminum dust cap is more than a visual marker—it’s part of a heat management system. Attached directly to the voice coil former, it acts as an active heatsink, pulling heat away from the core during operation. This means less thermal compression, more stable performance, and longer component life.

Mechanical Architecture Built to Last

• Die-cast aluminum frame prevents mechanical flex and supports rigid mounting
• Dual poly-cotton spiders stabilize cone movement across the entire excursion range
• High-temp adhesives hold the voice coil through punishing heat cycles
• UV-resistant polyether foam surround ensures linear motion without edge fatigue
• Nickel-plated, spring-loaded terminals accept 8-gauge speaker wire for low-resistance power transfer
