Next-gen Sound Performance
Dreaming of the next generational subwoofer to install in your car audio system, the Alpine R2-W12D4, which belongs to Alpine's newly updated R-Series subwoofers that are known for exceptional bass accuracy, power output, and reliability, is an excellent option you should look into.
High Amplitude Multi-Roll surround

Its new motor structure comes with massive double-stacked magnets allowing the subwoofer to produce an extensive low-frequency response and more solid bass control. All R-Series subwoofers, including the R2-W12D4, come with dual voice coils with many configurations to choose from, making them flexible in many subwoofer applications.
