P2D2/D4-12

The Rockford Fosgate Punch P2 subwoofers deliver powerful bass reproduction, high power handling, and Rockford Fosgate's proven sound quality. With a power handling capacity of 400 watts RMS and 800 watts peak, these 30 cm (12") subwoofers offer a compelling combination of deep bass, dynamics, and precision.

The robust design, featuring a 58 mm dual voice coil, a sturdy diaphragm made of a Kevlar-paper composite, and a generously sized foam surround, ensures reliable performance even at high volumes. The dual suspension ensures controlled diaphragm movement, while the aluminum voice coil former promotes efficient heat dissipation.

Thanks to the dual voice coil, the subwoofers can be flexibly adapted to different amplifiers. Both models are suitable for both sealed and bass-reflex enclosures.
