Max Bass, Slim Space

This Gen-2 version of Rockford Fosgate’s "T1 Slim" subwoofer is designed to deliver big bass in a compact, shallow design. It’s been re-engineered with more mass to fit in smaller enclosures and includes upgrades like a new surround and better heat management. The “P” (ported) version is designed for ported enclosures and work best in open-air environments (convertible).

The voice coil now uses pure copper wire for better conductivity, paired with a new composite former to dissipate heat and reduce distortion. The suspension utilizes a new polymer surround, made using an advanced NCDI (Nano Cell Direct Injection) process to enhance efficiency and durability without risking dry-rot.
