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.
