ORIGINAL ROCKFORD FOSGATE PRIME USA R1S4-12 400W 12" R1 4-OHM SVC SUBWOOFER

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.

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 high‐temp 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.
  • 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.
