Overview
The Power T1S1-10S is a re-engineered, slim 10" subwoofer from Rockford Fosgate’s T1 Slim series. It’s built for tight installations and small sealed enclosures, trading depth for strong low-frequency performance and improved thermal management.
Best for
- Small sealed enclosures and compact builds
- Tight mounting depth applications (slimline installations)
- Users who want tactile, efficient low-end from a single 10" driver
- Truck cabs and other closed environments where space is limited
Key points
- 10" slim profile designed for tight installations
- Single 1Ω single-voice-coil (SVC) configuration
- Re-engineered Gen-2 T1 Slim with increased mass and improved surround
- Enhanced thermal management features (composite former, aluminum spider spacer)
- Nano Cell Direct Injection (NCDI) bonded co-molded surround for durability and efficiency
- Dual spider suspension and voice coil composite former (VCCF) to reduce distortion
Fit and use
This S (sealed) version is optimized for small sealed enclosures and tight installs; it’s sold individually (1 each). Plan for an amplifier and wiring that can safely drive a 1Ω load and confirm enclosure volume and power handling using manufacturer specifications for best results.
What to know
Sold one per unit. The T1S1-10S uses a single 1Ω voice coil, so amplifier compatibility and wiring must be considered before installation. The slim design reduces required mounting depth, but exact enclosure volumes, mounting depth, and power handling numbers should be referenced from the manufacturer’s specifications…

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.
