The Rockford Fosgate T1S1-10P is a premium shallow-mount 10-inch Power Series subwoofer engineered specifically for ported enclosures and high-performance installs where mounting depth is limited. Unlike most shallow subs, the T1 Slim series was designed to deliver output and excursion levels close to full-size subwoofers while fitting in tight truck, SUV, and under-seat applications.
