P3D2/D4-10

The Rockford Fosgate Punch P3D2-10 and P3D4-10 are high-performance 25 cm (10-inch) subwoofers with 500 watts RMS and a maximum power handling capacity of 1,000 watts. The Punch P3 series was designed for powerful, precise bass reproduction with high excursion and is suitable for both sealed and bass-reflex enclosures.

The sturdy aluminum diaphragm with an aluminum dust cap ensures high rigidity and controlled bass reproduction. A durable Santoprene surround allows for large cone excursions, while the robust die-cast aluminum basket and dual suspension rings ensure mechanical stability.

Thanks to the 64-mm dual voice coil and a linear excursion of ±15.9 mm, these subwoofers offer high power handling and powerful low-frequency bass. Both models are technically very similar and differ mainly in their voice coil impedance.
