Featuring dual 4-ohm voice coils, the R2D4-12 provides versatile wiring options, allowing you to match the subwoofer's impedance to your amplifier's requirements.

Mica-injected Polypropylene Cone

Its linear spider design and integrated tinsel leads enhance cone control and reliability. Equipped with a StampCast steel frame, the R2D4-12 ensures stability and improved thermal management. This flexibility lets you optimize power handling and maximize the subwoofer's output.

Resulting in Consistent and Reliable Performance

The subwoofer's optimized motor structure and vented pole piece help dissipate heat, resulting in consistent and reliable performance over extended listening sessions. Whether upgrading your car's audio system or building a new one, the Rockford Fosgate R2D4-12 offers a reliable and cost-effective solution. With its solid construction and powerful performance, this subwoofer delivers deep, punchy bass that will enhance your overall listening experience on the road.

 Features:

  • Overview: The Rockford Fosgate Prime R2D4-12 is a 12-inch subwoofer with dual 4Ω voice coils. The sub features a StampCast steel frame, quick-release compression terminals, and a mica injected polypropylene cone. An anodized aluminum voice coil former and spider venting help keep the subwoofer cool.
  • Steel Basket: The R2D4-12 subwoofer features a StampCast steel basket for added rigidity.
  • Compression Terminals: The Prime R2D4-12 features spring post terminals which accommodate speaker wire up to 12 gauge.
  • CEA-2031 Compliant: Power handling on the Rockford Fosgate Prime R2D4-12 subwoofer conforms to CEA-2031 industry standards. This means the subwoofer has the capacity to handle power under continuous demand, not instantaneous power handling, that over time, can damage voice coils.
  • Sealed Box: Rockford recommends a sealed enclosure with an optimum internal volume of 1.02 cubic feet (from 0.75 to 1.25 cubic feet is acceptable). Sealed enclosures provide the most control over a woofer, will handle a lot of power, and provide accurate sonic reproduction, making them suitable to all types of music.
  • Ported Box: Rockford recommends a ported enclosure with an internal volume of 1.79 cubic feet using one 4" diameter x 9.3" long port; this yields a tuning frequency of 45 Hz. Ported (or vented) enclosures typically provide better overall efficiency than sealed so they are suitable for use with smaller amplifiers, giving you more bass output from less power. However, this efficiency comes at the expense of very low frequency output (below 40Hz).
