About this product
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 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.

The new design and enhanced performance of the R2-Series subwoofers offer deeper bass and tighter bass control compared to the previous generation. Updates to the new generation include larger, double-stacked magnets, an integrated Faraday ring, and a Kevlar-treated cone. All of these updates equal unmatched durability and reliable performance, even at high volumes. The R2-W10D4 handles up to 750 watts RMS, so it's ready for your high-powered amp. Its dual oversized 4-ohm voice coils offer wiring flexibility for multiple subwoofer setups. Since it works well in sealed or ported enclosures you'll enjoy your music the way you like to hear it.

The ZXI10.4D is a 10" car subwoofer from the DS18 ZXI series. It handles 800 watts RMS and uses dual voice coils at 4 ohms per coil, so you can wire multiple subwoofers to the final impedance your amplifier is stable at. Peak power handling is 1600 watts. The high-excursion motor and suspension let the cone travel farther for deeper low-frequency output. The motor uses a quad stacked magnet assembly. Mounting requires a 9.36" cutout diameter and 6.91" of mounting depth, so confirm your enclosure before installing. Pair it with a matching monoblock amplifier and a properly tuned enclosure to get the most low-frequency output.

The PSW12.2D is a 12" car subwoofer from the DS18 PSW series. It handles 600 watts RMS and uses dual voice coils at 2 ohms per coil, so you can wire multiple subwoofers to the final impedance your amplifier is stable at. Peak power handling is 1200 watts. The water-resistant cone holds up to moisture and spray in open-air installs. The shallow-mount basket fits tight spaces and under-seat enclosures where a standard-depth subwoofer will not clear. Mounting requires a 10.6" cutout diameter and 3.3" of mounting depth, so confirm your enclosure before installing. Pair it with a matching monoblock amplifier and a properly tuned enclosure to get the most low-frequency output.
