T2S1/S2-13

The Rockford Fosgate T2S1-13 / T2S2-13 from the high-performance Power T2 series is an uncompromising 33 cm (13-inch) high-end subwoofer designed for extreme bass performance and maximum power handling. With a continuous power handling capacity of 2,000 watts RMS and a maximum power handling capacity of 4,000 watts, this subwoofer was specifically designed for demanding car audio applications and exceptionally high sound pressure levels.

The extremely rigid glass-fiber-aramid honeycomb diaphragm, combined with the generously sized foam surround, ensures a high diaphragm excursion while delivering precise bass reproduction. A solid die-cast aluminum construction, the 101-mm voice coil, and the powerful triple-magnet system ensure high thermal and mechanical durability. The double Nomex centering spider supports controlled cone movement even at high power levels.

Thanks to its enormous power reserves and high-quality construction, the Power T2 is suitable for both high-performance music systems and demanding SPL applications.
