Alpine S2-W10D2

Next generation 25 cm (10 inch) S-Series subwoofer with dual 2-ohm voice coils.
Alpine's redesigned next-generation S-Series subwoofers use technology from our advanced basses to give you the depth and punch that bring your songs to life. With high-tech materials and Alpine expertise, these basses deliver the low notes you crave at a budget-friendly price.

The S2-W10D2 25cm (10") woofer handles up to 600 watts RMS, so you can drive it hard without any worries. The redesigned cone combines carbon fiber and polypropylene for low weight and robustness, while its rubber HAMR (High Amplitude Multi-Roll) surround allows for maximum excursion for impressive performance. Convenient jumpers make it easy to switch from 2 Ohm to 8 Ohm impedance to suit your system. This sub is equally suited to ported and sealed cabinets, so you can enjoy your bass big and boomy or tight and precise.
