Rockford Fosgate T1S2-10P 10" 2-Ohm Slim Subwoofer

The Rockford Fosgate T1S2-10P is a shallow-mount 10-inch subwoofer designed for vehicle installations where mounting depth is limited. Its 2-ohm single voice coil configuration is intended for systems using an amplifier stable at a 2-ohm load. This model is engineered specifically for a ported enclosure rather than a sealed box.

With 500 watts RMS and 1,000 watts maximum power handling, the T1S2-10P is suited to listeners building a compact system that still needs substantial low-frequency output. Its shallow 3.01-inch mounting depth helps it fit in space-restricted locations such as behind seats or in custom low-profile enclosures. The ported alignment supports a more output-focused bass presentation when installed in the recommended enclosure volume range.

This Power T1 Slim model uses a single 2.5-inch voice coil with pure copper wire and a composite voice-coil former. The motor structure incorporates an inductive damping heat sink and heat-dissipating frame fins to help manage operating temperatures. A high-energy neodymium motor supports the compact installation depth.

The moving assembly combines a carbon fiber, PMI, and glass-fiber cone with an aluminum dustcap. Its co-molded polymer surround uses Nano Cell Direct Injection construction, while dual progressive Nomex spiders help control cone movement. These materials and suspension components are designed for durable operation in a compact subwoofer format.

For a complete system, pair this subwoofer with a compatible mono or subwoofer amplifier that delivers appropriate power at 2 ohms, plus a properly designed ported enclosure. Rockford Fosgate recommends an infrasonic filter for vented installations to limit excessive low-frequency excursion. An active low-pass crossover in the 80-100 Hz range is also recommended in the owner’s manual for subwoofer integration.

Key Features

• Shallow 10-Inch Design: Uses only 3.01 inches of mounting depth for compact custom installations.
• Ported-Enclosure Alignment: Optimized for vented boxes and not recommended for sealed enclosures.
• 500-Watt RMS Handling: Supports amplifier matching for sustained bass output at its rated power.
• 2-Ohm Single Voice Coil: Provides a fixed 2-ohm nominal load for compatible amplifiers.
• Composite Cone Assembly: Combines carbon fiber, PMI, glass fiber, and an aluminum dustcap.
• Thermal Management: Uses a composite former, heat-sink structure, and cooling fins.

Design & Installation

The T1S2-10P uses a die-cast aluminum frame with integrated heat-sink fins, a detachable die-cast aluminum trim ring, and corrosion-resistant tin-plated brass push terminals. Its cone assembly uses a chemically bonded co-molded surround, symmetrical braided flat tinsel leads, and dual Nomex progressive spiders. The subwoofer accepts speaker wire through 10 AWG slot-loaded terminals.

Install the T1S2-10P in a rigid ported enclosure with a net internal volume between 1.0 and 1.50 cubic feet after allowing for woofer and port displacement. The recommended ported design is 1.25 cubic feet net, tuned to 40 Hz, using a 4-inch diameter by 13.75-inch long port. Confirm a 9.13-inch cutout and at least 3.01 inches of mounting depth, then use an infrasonic filter 5-10 Hz below enclosure tuning for vented operation.
