Rockford Fosgate T3S2-19 19" 2-Ohm Superwoofer

The Rockford Fosgate T3S2-19 is a 19-inch single-voice-coil car subwoofer built for systems that need substantial low-frequency output and have room for a large custom enclosure. Its 2-ohm nominal impedance is intended for use with a properly matched external mono or subwoofer amplifier. With 3,000 watts RMS power handling, it is suited to advanced, high-power vehicle audio installations.

This Power T3 Superwoofer is designed to reproduce deep bass with a large effective cone area and long linear excursion. Its 21-250 Hz frequency-response rating and 27.5 Hz free-air resonance support low-bass-oriented system designs. The 90 dB sensitivity specification helps characterize its output potential when paired with appropriate amplification and enclosure design.

The T3S2-19 uses a three-layer glass fiber, Aramid honeycomb, and glass fiber cone with an aluminum dustcap. An injection-molded foam surround incorporates Rockford Fosgate's VAST geometry, while dual Nomex progressive spiders support the moving assembly. These components are designed to maintain cone control during high-excursion operation.

A dual-gap, multi-pole neodymium push/pull motor works with dual separated, single-layer edge-wound aluminum 5-inch voice coils. The die-cast aluminum frame integrates heat-sink fins and venting to support thermal management. Its large motor and moving assembly make this a specialized subwoofer for dedicated bass systems rather than a compact factory-replacement upgrade.

Installation requires careful planning because the driver has a 20.98-inch overall diameter and a 15.66-inch mounting depth. Rockford Fosgate specifies a high-output vented enclosure with 8.0 cubic feet of total internal volume, including driver and port displacement. Use an amplifier that is stable at the final 2-ohm load and size the enclosure, wiring, electrical system, and mounting structure for this subwoofer's power and physical requirements.

Key Features

• 19-Inch Superwoofer Platform: Provides substantial cone area for high-output bass systems.
• 3,000W RMS Handling: Supports properly engineered high-power amplification.
• 2-Ohm Single Voice Coil: Presents one nominal 2-ohm amplifier load.
• 5-Inch Edge-Wound Coils: Uses aluminum windings in a push/pull motor.
• Three-Layer Composite Cone: Combines glass fiber and Aramid honeycomb materials.
• Dual Nomex Spiders: Supports controlled high-excursion cone movement.

Design & Installation

The T3S2-19 combines a composite cone, aluminum dustcap, injection-molded foam surround, and die-cast aluminum frame. Its frame includes integrated heat-sink fins and venting, while the motor uses a dual-gap, multi-pole neodymium push/pull structure. An integrated die-cast aluminum trim ring and proprietary mechanical surround clamping ring complete the assembly.

Plan for a 17.72-inch mounting opening, 15.66 inches of mounting depth, and a rigid baffle that can support the driver's size and mass. Rockford Fosgate's high-output vented recommendation uses 8.0 cubic feet total internal volume, with 6.4 cubic feet net internal volume after 0.34 cubic feet of woofer displacement and 1.26 cubic feet of port displacement. Connect speaker cable to the insulated 4 AWG compression terminals, and have a qualified installer complete the enclosure, amplifier, wiring, and vehicle electrical integration when needed.
