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
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.
