Product details
Power T1 Slim 10-inch 1-ohm bass
T1S1-10 is Rockford’s Power Series slimline 10-inch single 1-ohm woofer for spaces where a full-depth sub will not fit. Continuous power handling is 500 W RMS / 1000 W max. Sensitivity is 82 dB (1 W/1 m) or 85 dB (2.8 V/1 m). Fs is 42 Hz with 15 mm Xmax. Magnet weight is 15.1 oz (0.43 kg). Shipping weight is 9.6 lb (4.3 kg). Rockford optimizes this model for sealed enclosures.

Cone, motor, and frame
A linear carbon-fiber / PMI / glass-fiber cone pairs with an aluminum dustcap. Dual Nomex progressive spiders with stitched tinsel leads and a dual-wound 2.5-inch CCA voice coil with interior/exterior windings handle excursion in the shallow motor. A high-temp, high-energy neodymium motor structure and injection-molded foam VAST surround keep the package thin. A die-cast aluminum frame with integrated heat-sink fins and custom 10-AWG slot-loaded brass push-spring terminals finish the package. An optional protective grille insert is available separately.

Fit and enclosure
Mounting depth is 3.01 inches (76.5 mm) with a 9.13-inch (232 mm) cutout. Rockford Fosgate recommends a sealed volume of 0.8 cu. ft. (22.6 L) and a vented volume of 1.5 cu. ft. (42.4 L). Woofer displacement is 0.028 cu. ft. (0.82 L). A detachable die-cast aluminum trim ring is included. Confirm amplifier stability into 1 ohm before install.
