The Pioneer TS-A301S4 Champion Series 12" subwoofer evolves from Pioneer’s award-winning SPL Champion Edition legacy, delivering deep, powerful bass with improved efficiency and sensitivity. A redesigned large motor assembly and reinforced basket structure help reduce vibration while maintaining strength, resulting in cleaner low-frequency output and better overall sound quality.

Built for high output with reduced distortion, this subwoofer features an advanced 2-piece cone design using a highly rigid Honeycomb IMPP™ composite cone plus a rigid drive cone for strong performance during high excursion. With 500W RMS continuous power handling and 1,600W peak power, a single 4-ohm voice coil, and a vented pole yoke for enhanced cooling, the TS-A301S4 is a dependable upgrade for serious car audio bass performance.
