Rockford Fosgate T1D412 12" Power Series Subwoofer
The Rockford Fosgate T1D412 is a high-output 12-inch subwoofer engineered for powerful, accurate bass with excellent control and durability. As part of the Power Series lineup, it’s built to handle serious power while maintaining clean low-frequency response in demanding audio systems.
It features a dual 4-ohm voice coil design with Rockford Fosgate’s SWIFT™ selectable impedance system, allowing flexible wiring options for 2-ohm or 8-ohm configurations. This makes it easy to match with a wide range of amplifier setups, from high-powered mono amplifiers to multi-subwoofer builds.
The cone is made from Kevlar®-reinforced paper with an aluminum dust cap for strength and reduced distortion at high excursion. A cast aluminum basket improves rigidity and heat dissipation, while the VAST™ surround increases effective cone area for stronger bass output from the same footprint.
Rated at 800 watts RMS and 1600 watts peak, the T1D412 performs exceptionally well in both sealed and ported enclosures, making it a solid choice for high-performance systems that demand deep, controlled bass with real output capability.
