Alpine's RS-W12D4 12-inch R-Series Shallow Subwoofer with Dual 4-Ohm Voice Coils. With an ultra-shallow subwoofer design and powerful sound output, the R-Series Shallow Subwoofers give you the best of both worlds in size and sound. A lightweight yet rigid aluminum dust cap allows the R-Series Shallow Subwoofer to transition sound quickly with mini... moremal distortion and project the bass off the surface of the speaker for hard-hitting yet smooth bass performance. 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. Don’t let the size 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.
