Features

Overview: The Pioneer TS-W303R 12-inch, 4-ohm component subwoofer handles 1,200 watts max. (250 watts RMS nominal power), and features Pioneer's extremely strong and lightweight IMPP Composite Cone Woofer, for improved sensitivity and reduced distortion. The TS-W303R features a double cone woofer design with reinforcement nodes to deliver higher power handling and deeper bass, and a 6-Layer Long Voice Coil adds extra power and control. In addition, the woofer's Wide-Roll Urethane Surround provides excellent control for your big bass notes, and the woofer's Projected Pole Yoke with Vented Pole delivers tight, powerful sound with lower distortion.

IMPP Woofer: The Pioneer TS-W303R features an IMPP (Injection Molded Polypropylene) woofer cone. The IMPP cone design provides the strength and rigidity powerful bass sound requires.

Surround: The Wide-Roll Urethane Surround provides excellent control for big bass notes.

Voice Coil: The woofer's 6-layer long voice coil design allows expanded piston motion for better linearity, improved power handling, and more bass impact.

Projected Pole Yoke: The projected pole yoke extends the magnetic field, greatly improving linearity during large woofer excursions at high input levels.

Vented Pole Yoke: The vented pole yoke allows air circulation within the motor structure to ensure better heat dissipation.

Terminals: The heavy duty spring compression terminals will accept bare wire up to 10 gauge, pin connectors, and single banana plugs.

Optional Grille: We recommend covering up the subwoofer with the Pioneer Subwoofer Grille (130UDG308, sold separately). This stylish spoke grille is made of durable ABS plastic.
