T3S1/S2-19

The Rockford Fosgate Power T3S1-19 / T3S2-19 is an uncompromising 19-inch high-performance subwoofer designed for extreme bass performance and demanding car audio installations. With a power handling capacity of 3,000 watts RMS and up to 6,000 watts of peak power, the Power T3 series offers enormous power reserves for powerful and deep bass reproduction.

The exceptionally rigid glass-fiber-aramid sandwich diaphragm, a solid die-cast aluminum construction, and the exceptionally large 127-mm aluminum voice coil ensure high power handling and precise diaphragm control. The sophisticated push-pull neodymium magnet system ensures powerful drive, while the special VAST foam surround allows for large diaphragm excursions.

With a linear stroke of ±34 mm, dual progressive Nomex centering cones, and a sophisticated ventilation system, this subwoofer has been specifically designed to meet extreme low-frequency demands.
