Dual-Coil Subwoofer (4 ?) 12" / 30 cm

Alpine's redesigned next-generation S-Series subwoofers apply technology from our higher end subs to bring you the depth and punch that'll make your tunes come alive. With high-tech materials and Alpine know-how, these subs deliver the lows you crave at a budget-friendly price.

The S-W12D4 30 cm (12") sub handles up to 600 Watts RMS, so you can drive it hard without any worries. The redesigned cone combines carbon fiber and polypropylene for light weight and sturdiness, while its rubber High Amplitude Multi-Roll (HAMR) surround enables maximum excursion for impressive performance. Handy jumpers make it simple to switch from 2 Ohm to 8 Ohm impedance to adapt to your system. This sub is equally suited for ported and sealed boxes, so you can enjoy your bass big and boomy or tight and precise.
