Stitched Tinsel Leads

Improved reliability and performance by reducing fatigue and possible shorting.


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.
