More about the product
The Pioneer TS-W312D4 Champion Series 12-inch subwoofer is built for powerful bass performance in custom car audio setups. It features a rigid IMPP (Injection-Moulded Polypropylene) cone with Honeycomb design, designed to handle high sound pressure levels while maintaining clarity and control. This cone material is lightweight yet strong, helping reduce distortion even at high volumes.
The subwoofer uses a dual 4-ohm voice coil configuration, allowing flexible wiring options for different amplifier setups. It supports both series and parallel wiring, making it suitable for single or multi-subwoofer systems. With a maximum power handling of 1600 watts and a nominal rating of 500 watts, the TS-W312D4 is capable of delivering deep, impactful bass when paired with a suitable amplifier.
Its large magnet and heavy-duty motor structure are designed to improve power handling and responsiveness. The subwoofer also includes a high-efficiency cooling system to manage heat during extended use, helping maintain consistent performance.
The TS-W312D4 has a frequency response of 20 Hz to 1.6 kHz, focusing on low-end reproduction. It is intended for use in sealed or ported enclosures, depending on the desired sound characteristics. Sealed boxes offer tighter, more accurate bass, while ported designs provide louder, more resonant output.
Installation requires a custom enclosure and proper amplifier matching. The subwoofer does not include built-in amplification or wireless features. It is a passive unit designed for integration into aftermarket sound systems.
The Champion Series design includes a sleek black finish with a bold logo, giving it a clean, aggressive look that suits performance-oriented builds. The subwoofer is built for durability and long-term use, with a strong basket and surround to handle heavy bass output.
While the TS-W312D4 offers excellent bass performance, it requires careful setup and tuning to achieve the best results. It is not suitable for factory speaker replacements or plug-and-play installations.
