The R1S4-12 features a 4-Ohm Single Voice Coil design, 200 Watt RMS power handling, and is optimized for both sealed and vented enclosures.
Overview
Rockford Fosgate Prime R1 12” subwoofers provide high performance bass at an unbelievable value. This model features a laser etched curvilinear dust-cap to dissipate heat generated by the highâtemp copper voice coil as well as a solid stamped steel frame with integrated frame mounted compression terminals. Best of all, they are optimized for both sealed and vented enclosures.
Technologies
CEA-2031
Power handling on Rockford Fosgate speakers conform to CEA-2031 industry standards.
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.
