Klippel Verified

Klippel is a speaker certification program allowing us to deliver the best possible subwoofers.

FlexFit Basket

The slot mounted frame pattern allows fine-tuning of the subwoofer's mounting position.

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.

Stitched Tinsel Leads

Improved reliability and performance by reducing fatigue and possible shorting.
