The Rockford Fosgate T1S2-10S is a premium shallow-mount 10-inch Power Series subwoofer engineered specifically for sealed enclosures and ultra-tight installation spaces. Unlike most shallow subwoofers that sacrifice output and excursion, the redesigned Gen-2 T1 Slim series was built to deliver serious low-end bass, strong thermal handling, and excellent musical accuracy while fitting in applications where traditional subwoofers simply will not fit. It’s especially popular in trucks, under-seat builds, stealth systems, and space-limited SQL installations.
