More about the product
The Pioneer TS-W312S4 Champion Series 12-inch subwoofer is designed to deliver deep, punchy bass for custom car audio systems. It features a rigid IMPP (Injection-Moulded Polypropylene) cone with Honeycomb design, which helps reduce distortion and maintain clarity even at high volume levels. This cone material is lightweight and strong, making it ideal for handling powerful low frequencies.
The subwoofer uses a single 4-ohm voice coil, offering straightforward wiring for most amplifier setups. With a peak power handling of 1600 watts and a nominal rating of 500 watts, the TS-W312S4 is built to produce strong bass output when paired with a suitable amplifier. Its large magnet and robust motor structure improve responsiveness and overall sound pressure.
The TS-W312S4 has a frequency response of 20 Hz to 1.6 kHz, focusing on low-end reproduction. It is designed 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.
The subwoofer includes a durable steel basket and a high-compliance surround to support long excursion and consistent performance. It also features a cooling system to manage heat during extended use, helping maintain reliability over time.
Installation requires a custom enclosure and proper amplifier matching. The TS-W312S4 does not include built-in amplification or wireless features. It is a passive unit intended for integration into aftermarket sound systems.
The Champion Series styling includes a sleek black finish with bold branding, giving it a clean and aggressive look that suits performance-focused builds. While the TS-W312S4 offers strong 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.
