P1S2/S4-12

The Rockford Fosgate Punch P1S2-12 and P1S4-12 subwoofers deliver powerful bass reproduction, high reliability, and a rugged design. With a power handling capacity of 250 watts RMS and 500 watts peak, these 30 cm (12-inch) subwoofers are suitable for both sealed and bass-reflex enclosures.

The durable diaphragm design, a heat-resistant 50-mm voice coil, and the specially developed suspension system ensure controlled diaphragm movement and precise bass reproduction. The sturdy steel basket, the high-density foam surround, and the integrated connection wires ensure a durable design even under demanding conditions.

Both models are largely identical in terms of technical specifications and differ mainly in their impedance, which is 2 ohms and 4 ohms, respectively. This allows you to select the subwoofer that is compatible with the power amplifier you are using.
