Alpine S2-W10D4

$200.00

S-Series 10″ subwoofer with dual 4-ohm voice coils

Great bass for less. For the best in bass, you need the best in materials and engineering. Alpine’s redesigned Next-Generation S-Series subwoofers apply technology from their 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. Redesigned for better sound. The S-W10D4 10″ 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 sealed and ported boxes, so you can enjoy your bass big and boomy or tight and precise. A twist-lock mounting system makes it easy to add one of Alpine’s specially-designed speaker grilles (sold separately).
