Overview

The Power Series T1D212 Dual 2-Ohm subwoofer builds on innovative new Rockford Fosgate technologies. These bad boys have patented VAST technology that increases surface cone area up to 25% so the T1D212 performs like a much larger woofer over the previous model. The new FlexFit basket not only looks the part but it provides extreme flexibility for extreme installations. Clean, high tech and ready to set off car alarms, the T1D212 is here!

Anodized Aluminum Voice Coil Former
Anodized Aluminum Voice Coil Former

Rockford Fosgate subwoofers use anodized aluminum voice coil formers that provide superior heat dissipation (up to 100° at full power levels). Unlike traditional plastic substitutions, aluminum acts like a heat-sink to quickly dissipate thermal build-up on the voice coil. This keeps subwoofers cool during high SPL conditions.
