Additional details

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 “S” sealed version is designed for smaller sealed enclosures and work best in closed environments (truck cab).

 

The voice coil now uses pure copper wire for better conductivity, paired with a new composite former to dissipate heat and reduce distortion. Additionally, an aluminum spider spacer improves cooling.  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.
