The Pioneer TS-W32D4 is a 30 cm (12-inch) Champion Series component subwoofer designed to deliver deep, accurate bass for car audio systems requiring strong low-frequency performance. With a maximum power handling of 1500 W and a nominal output of 400 W, it is suitable for a wide range of amplifier configurations. Built with Pioneer’s rigid and lightweight IMPP™ (Injection Moulded Polypropylene Composite) cone, the TS-W32D4 reduces distortion while maintaining clarity at high output levels. The dual 4-ohm voice coil design provides flexible wiring options, making it ideal for custom installations in sealed or ported enclosures.
