Alpine S2-W12D4


Performance and Value

With an impressive power handling of 600W RMS and a peak power handling of 1800W, the Next-Gen 12” S-Series Subwoofers deliver outstanding performance value. Boasting a wide frequency response range of 23Hz to 215Hz and a sensitivity of 86dB (1W/1m), these subs ensure powerful and accurate bass reproduction across a diverse range of music genres.

Enhanced Punch

Featuring the lightweight yet sturdy combination of carbon fiber and polypropylene, the Next-Gen S-Series Subwoofer cone delivers deep, low-distortion bass that enhances the depth and richness of your music.

HAMR Surround

Alpine-exclusive High Amplitude Multi-Roll (HAMR) surround technology is integrated into the speaker design which allows for maximum cone movement, delivering powerful and accurate bass notes.

Flexible Application

A dual voice coil (DVC) with easy configuration jumpers make installing the s-series subwoofers a breeze. A new twist-lock grille mounting system makes it easy to install and remove an optional grille without mounting screws for added protection to the cone.

Perfect Power Match

Maximize the potential of your s-series subwoofers with Alpine's perfectly power-matched s-series amplifiers. Power a single S2-W12D4 subwoofer effortlessly with the 600 watts S2-A60M mono amplifier, or for a even bigger impact, pair two or more S2-W12D4 subwoofers with the powerful 1200 watts S2-A120M amplifier to ensure optimal sound quality and performance.
