Alpine S-W12D2

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 si... moreze fool you – the R-Series Shallow Subwoofers feature the same motor 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 houses the lightweight and powerful neodymium magnet for 600W RMS of power handling. Precise Bass Control Alpine’s Gen2 DD-Linear Magnetic Circuit technology, a compact and efficient dual-gap voice coil structure, allows for better control over the motor, resulting in lower distortion and precise bass control.
