Rockford Fosgate R2D2-12

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.

Power handling on Rockford Fosgate speakers conform to CEA-2031 industry standards. This means your speaker has the capacity to handle power under continuous damand, not instantaneous power handling, that over time, can damage voice coils.

Allows nominal impedance of voice coils to quickly be configured in a Series or Parallel wiring configuration. Also provides built-in fusing for protection from voltage transients. Removing and inverting the center plug, a Series or Parallel wiring configuration is accomplished. The removable impedance selection jumper also provides fused protection in severe overload conditions.

Multipoint "periodic" stitched lead wire technique reduces the mass of each tinsel lead and spreads stress and strain over a greater area, significantly improving the reliability and performance of the subwoofer.  These stitched tinsel leads withstand extreme duty cycles, fatigue and high current that is critical to robust design.

Secures directly to the top of magnet structure to improve system efficiency by reducing both distortion and back EMF (Electo-magnetic force). Also radiates heat to reduce voice coil temperature.

The Vertical Attach Surround Technique significantly increases a speaker's effective radiating cone area without complicated installation issues. The result provides up to 25% more effective radiating cone area for the same model speaker. VAST significantly increases a speakers effective radiating cone area without complicated installation issues. This design alters the typical design and manufacturing technique by eliminating the large flat glue surface area (the landing) which allows the surround to be shifted for increased cone area. In turn, both nominal efficiency and maximum output capabilities are dramatically improved.
