Features:

• CEA-2031
  Power handling on Rockford Fosgate speakers conform to CEA-2031 industry standards.
• Klippel Verified
  Klippel is a speaker certification program allowing us to deliver the best possible subwoofers.
• Stitched Tinsel Leads
  Improved reliability and performance by reducing fatigue and possible shorting.
• 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.
• VAST Surround - Subs
  The Vertical Attach Surround Technique significantly increases a subwoofer's effective radiating cone area up to 25%.
• FlexFit Basket - Subwoofer
  The slot mounted frame pattern allows fine-tuning of the subwoofer's mounting position.
