The New 2023 S-Series Subwoofers

The S2-W12D2 is Alpine's redesigned next-generation S-Series 12" (30cm) subwoofer, built for powerful and reliable bass performance at an approachable price. Alpine's higher-end subwoofer technology has been carried across into the S-Series, giving you depth and punch without the premium cost.

Performance & Value

With 600W RMS and 1800W peak power handling, the S2-W12D2 can be driven hard. A wide frequency response of 23Hz to 215Hz and a sensitivity of 86.2dB (SPL@1W/1m) ensure accurate, powerful bass across a broad range of music.

HAMR Surround

The S2-W12D2 uses Alpine's High Amplitude Multi-Roll (H.A.M.R.) surround technology. This rubber surround allows the cone to move air efficiently while keeping temperatures down, enabling 15mm of one-way excursion for precise bass output.

Enhanced Punch

The cone combines carbon fibre and polypropylene for a lightweight yet rigid construction, delivering deep, low-distortion bass with minimal colouration.

Flexible Application

Dual Voice Coil (DVC) wiring with easy configuration jumpers lets you adapt the sub to your amplifier setup. A twist-lock grille mounting system allows an optional grille to be fitted and removed without screws. The S2-W12D2 performs well in both sealed and ported enclosures — sealed for tight, accurate bass or ported for a bigger, roomier sound.

Perfect Power Match

Alpine recommends pairing the S2-W12D2 with S-Series amplifiers for a power-matched system. A single S2-W12D2 works well with the 600W S2-A60M mono amplifier. For a larger installation, two or more S2-W12D2 subwoofers can be driven by the 1200W S2-A120M amp. You can also add the Alpine RUX-KNOB2 remote bass level control for convenient volume adjustment from the driver's seat.

Sizes & Variations

The S-Series subwoofer range is available in 8", 10" and 12" sizes, in dual 2Ω and dual 4Ω impedances. If you need more output, the Alpine R2-W12D2 steps up to Alpine's R Series with 750W RMS from the same 12" format.

Made for S-Series Amps & Subs

The S-Series subwoofer line is designed to integrate with Alpine's S-Series amplifiers and speakers for complete system building. S-Series components are aimed at those who want a great-sounding, Hi-Res Audio capable setup without overspending.
