Alpine RS-W12D4
The Alpine RS-W12D4 is a 12-inch R-Series dual 4-ohm subwoofer engineered for powerful, precise, and deep bass performance. It delivers up to 750W RMS and 2250W peak power, making it ideal for high-performance car audio systems. Featuring a Kevlar-reinforced pulp cone and HAMR (High Amplitude Multi-Roll) surround, the RS-W12D4 ensures superior control, durability, and consistent performance even under heavy loads. Its dual 4-ohm voice coils allow flexible wiring configurations, while the optimized motor structure minimizes distortion for clean, impactful bass reproduction.
Ultra-Shallow Design
For those looking to add powerful, hard-hitting bass performance to their vehicle but lack the space to add a subwoofer, Alpine’s R-Series Shallow Subwoofer delivers the same fun and loud sound you’ve come to expect, now in a shallow subwoofer that’s designed to fit in most vehicle applications.
Extreme Output
Don’t let the size fool you – the R-Series Shallow Subwoofers feature the same cone movement (20MM of excursion) as the full-size R2-Series Subwoofers for extreme output in a shallow woofer design. At the heart of the R-Series Shallow Subwoofers is an oversized 4-inch voice coil that is controlled by a powerful neodymium magnet for 600W RMS of power handling.
