Description

The Sub At A Glance:

  • Shallow Design: An elevated motor structure reduces mounting depth for installations where space is limited.
  • Power Handling: Handles 200 watts RMS and 400 watts maximum power.
  • Dual Voice Coils: Dual 4-ohm voice coils provide flexible wiring configurations.
  • Reinforced Cone: The mica-reinforced polypropylene cone helps reproduce clean, accurate bass notes.
  • Linear Suspension: A linear spider features embedded 16 AWG tinsel leads.
  • Vented Frame: The StampCast basket incorporates spider venting to help keep the motor cool.
  • Sealed-Enclosure Ready: Optimized for use in sealed enclosures.
  • Installation Hardware: Includes 12 AWG compression terminals and an integrated PVC trim ring.

When mounting depth is limited but the music still needs weight, the Rockford Fosgate R2SD4-10 brings low-frequency depth into compact installations. Its 10-inch cone adds a deeper rumble and noticeable impact to every bass line, while the shallow design makes it easier to build satisfying bass into space-conscious systems.
