T1S1/S2-10

The Rockford Fosgate T1S1-10 and T1S2-10 from the high-performance Power T1 Slim series combine powerful bass reproduction with an exceptionally slim design. Thanks to their shallow mounting depth of just 76.5 mm, these 25 cm (10-inch) subwoofers are ideal for space-saving installations where high bass performance is a must despite limited installation space.

The innovative split-yoke motor technology enables a particularly compact design with high load capacity. A sturdy fiberglass diaphragm, a die-cast aluminum basket, and a powerful neodymium magnet drive ensure precise diaphragm control and high mechanical stability. The integrated copper cap aids in heat dissipation and reduces unwanted distortion.

With 500 watts RMS and a maximum power handling capacity of up to 1,000 watts, the T1 Slim subwoofers offer an impressive combination of power, deep bass, and a compact design. Both models are specifically optimized for sealed subwoofer enclosures.
