The Rockford Fosgate T1S1-12 12″ Subwoofer is a slimline 12″ subwoofer designed for spaces where traditional sized woofers will not fit. It features a single 1-Ohm voice coil for simplified wiring configurations.

The T1 ‘Slimline’ subwoofers are not your average shallow, in fact, they have been painstakingly designed to near exact performance characteristics of traditional sized Power T1 subwoofers you’re already familiar with. We’re calling these ‘slim’ subwoofers because they don’t take a lot of depth and offer bass responses similar to a traditional sized model. How can this be true? Well, let’s just say the Wizards-of-Fos engineered an ingenious slotted voice coil assembly that exhibits long excursion travel. Don’t worry, you don’t need to understand how it works, you just have to listen to how awesome they sound!

Main Features:

  • Carbon fiber/PMI/glass fiber cone with aluminium dustcap
  • Injection molded foam surround with VAST™
  • Dual Nomex progressive spiders with integrated lead wires
  • Aluminium die-cast frame with integrated heat sink fins
  • Custom insulated push spring 10 AWG terminals
  • Dual wound 2.5″ voice coil with interior/exterior windings
  • Encapsulating voice coil to former coupling technology (patent pending)
  • Detachable die-cast aluminium trim ring
  • Vented pole piece
  • High temp high energy neodymium motor structure
  • Proprietary split yoke pass thru motor technology (patent pending)
  • Integrated copper cap heat sinking shorting ring (IDHS)
  • Optional grille insert available
  • Optimised for sealed enclosures
  • CEA-2031 Compliant
