High-performance
The Alpine S-W12D2 is a high-performance 12-inch subwoofer designed to deliver powerful and accurate bass in-car audio systems. Engineered with precision and attention to detail, this subwoofer offers exceptional low-frequency reproduction with impressive clarity and impact.
Bass Reproduction Without Distortion
With a peak power handling of 1800 watts and RMS power handling of 600 watts, the S-W12D2 can handle high-power amplification, allowing for intense and dynamic bass reproduction without distortion. It features a dual 2-ohm voice coil configuration, providing flexibility in wiring options to match your amplifier's capabilities.
Subwoofer Utilizes a Cone
The subwoofer utilizes a cone from a specialized pulp/Kevlar composite material, offering excellent rigidity and responsiveness. This construction allows the cone to reproduce low-frequency sounds with minimal distortion accurately. Additionally, the subwoofer features a high-excursion HAMR (High Amplitude Multi-Roll) surround, allowing for extended cone movement and maximum output.
Integrated Dual-stacked Magnet Assembly
The S-W12D2 incorporates a robust motor structure with an integrated dual-stacked magnet assembly to ensure reliable and consistent performance. This design promotes efficient heat dissipation and reduces power compression, enabling the subwoofer to deliver consistent and powerful bass even during demanding listening sessions.
