The Sub At A Glance:

  • Power Handling: Handles 800 watts RMS and 1,600 watts maximum for forceful low-frequency output.
  • Dual Voice Coils: Dual 4-ohm voice coils with a 3-inch diameter provide flexible wiring options.
  • Reinforced Cone: Kevlar fiber-reinforced paper cone delivers the toughness needed for hard-hitting bass.
  • VAST Technology: Increases cone surface area by up to 25%, helping this 12-inch subwoofer perform like a larger woofer compared with the previous model.
  • Durable Suspension: Symmetrical dual progressive-roll, tear-resistant poly-cotton spiders support demanding cone movement.
  • Rigid FlexFit Basket: Die-cast aluminum construction adds durability while providing flexibility for challenging installations.
  • Heat-Ready Construction: A high-temperature voice coil, spun-laced Nomex reinforcement collar, heat-sinking aluminum dust cap, and optimized venting help manage heat.
  • Installation Details: Proprietary 8 AWG insulated all-metal spring terminals and an included grille with an integral trim ring complete the package.

The T1D412 brings bass you can feel through the cabin, adding deep rumble beneath the music and solid impact when the beat drops. Its reinforced cone, durable suspension, and rigid aluminum basket are built to keep that low-end response controlled as the volume rises.
