Hard-hitting Bass

Dreaming of the next generational subwoofer to install in your car audio system, the Alpine R2-W8D4, 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. The Alpine R2-W8D4 comes with a Kevlar-treated cone, giving this 8-inch subwoofer the durability necessary to produce high-quality bass at loud volumes for extended periods. It also has Alpine's High Amplitude Multi-Roll surround, which allows the cone to perform at a maximum level while having excellent thermal efficiency.

Wiring Flexibility

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-W8D4, come with dual voice coils with many configurations to choose from, making them flexible in many subwoofer applications. The Alpine R2-W8D4 is a subwoofer with a power output of 350 Watts RMS and 1000 Watts peak power at 4 ohms. Its sensitivity rate of 83.7 dB and frequency response of 30 up to 200 Hz tells it all that this 8-inch subwoofer won't have any problems performing heart-pounding bass tracks at loud volume levels.
