Innovative technologies allow the T1D215 subwoofer to perform like a larger woofer over the previous model. The T1 15” features dual 2-Ohm voice coils, 1,000 Watts RMS power handling, and includes a grille with integral trim ring.
Overview
The Power Series T1D215 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%. 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 T1D215 is here!

Technologies
Stitched Tinsel Leads
Improved reliability and performance by reducing fatigue and possible shorting.
CEA-2031
Power handling on Rockford Fosgate speakers conform to CEA-2031 industry standards.
VAST Surround - Subs
The Vertical Attach Surround Technique significantly increases a subwoofer's effective radiating cone area up to 25%.
Klippel Verified
Klippel is a speaker certification program allowing us to deliver the best possible subwoofers.
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.
FlexFit Basket - Subwoofer
The slot mounted frame pattern allows fine-tuning of the subwoofer's mounting position.
SWIFT™ Terminals
Allows the voice coils to quickly be configured in a Series or Parallel wiring configuration.
Inductive Damping Heat Sink
Secures directly to the top of magnet structure to improve system efficiency by reducing both distortion and back EMF (Electo-Magnetic force). Also radiates heat to reduce voice coil temperature.
