About the Pioneer TS-W251R
You'll rock steady with the Pioneer TS-W251R 10" subwoofer riding in your car. This reliable performer provides great sound and a great value, so you won't have to run up a big tab to build a great system.
There's no compromise on quality, though. The deep blue polypropylene woofer cone rides in a sturdy wide roll urethane surround that promotes forceful lows, while a molded gasket ensures an airtight fit when you mount the sub in a box. Special cooling vents allow the heavy-duty voice coil to withstand continual hard use.
The TS-W251R matches up well with small sealed boxes — perfect if you like your bass accurate and deep. Sturdy spring compression wire terminals grab tight onto speaker wire for extra reliability.

Product Research
Cone: The TS-W251R 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, Dual-Layer Urethane Surround provides excellent control for big bass notes.
Voice Coil: The woofer's 4-layer long voice coil design allows expanded piston motion for better linearity, improved power handling, and more bass impact.
Extended Pole Yoke: The extended 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 or dual banana plugs.
Sealed Box Volume: The sealed box sizes recommended by Pioneer range from 0.7 cu/ft to 1.3 cu/ft. Within this range, the ideal size recommended by Pioneer is 1.0 cu/ft.
