Product Details
Alpine 10" Type-S Series Subwoofer (2ohm+2ohm), Model SWS1022D
The Type-S subwoofers were really great last year and this year Alpine made them even better! They've got heavy-guage custom-stamped steel frames that are much thicker than competing brands, for extra durability. Plus lots of very high quality parts like Santoprene surrounds and dual Nomex spiders that make them a great value.
