Shallow-mount Subwoofer

The Rockford Fosgate R2SD4-10 is a 10-inch shallow-mount subwoofer that combines compact design with powerful bass performance. This subwoofer is specifically designed for installations where space is limited but high-quality bass is desired.

Improved Power Handling and Thermal Management

Featuring a dual 4-ohm voice coil configuration, the R2SD4-10 offers versatile wiring options, allowing users to tailor their setup to their specific amplifier and impedance requirements. The dual voice coils also improve power handling and thermal management, ensuring reliable and efficient performance.

Mica-injected Polypropylene Cone

The subwoofer's mica-injected polypropylene cone delivers accurate and responsive bass, while the optimized surround allows for a maximum excursion, resulting in enhanced low-frequency output and improved sound quality. Its shallow-mount design enables easy installation in tight spaces, making it suitable for various vehicles and enclosures.

Impactful Bass Reproduction

With a power handling capability of up to 200 watts RMS, the R2SD4-10 packs a punch and adds depth to your audio system. Whether listening to rock, hip-hop, or electronic music, this subwoofer provides tight and impactful bass reproduction, enhancing your overall listening experience and immersing you in the music.

  • Diameter : 10 Inch
  • Sensitivity : 83 dB
  • Impedance : 4 Ohm
  • Frequency Response : 38-250 Hz
  • Peak Power Handling : 400 Watts
  • Shallow Mount : Yes Inch
  • Number of Voice Coils : Dual
  • Suggested Sealed Box Volume : 0.7 Cubic ft.
  • Suggested Ported Box Volume : 1.4 Cubic ft.
  • RMS Power Handling : 200 Watts

 Features:

  • Shallow Mount Design: The Rockford Fosgate Prime R2 Shallow Subwoofer is designed and engineered with a much smaller motor assembly which reduces the overall depth of the woofer allowing it to fit in shallower enclosures and tighter locations of your vehicle.
  • Dual 4-ohm Voice Coils: This woofer features dual 4-ohm voice coils to offer wiring flexibility. When the voice coils are wired in parallel the woofer presents a 2-ohm load, when wired in series it presents an 8-ohm load.
  • Spring Post Assembly: The woofer features compression input terminals with attached 16-gauge stitched tinsel lead wires. The nickel plated spring posts will accept pin connectors, single banana plugs, and bare wire up to 12-gauge.
  • Sealed Box Volume: Rockford Fosgate recommends a sealed enclosure with an optimum internal volume of 0.7 cubic feet (from 0.5 to 0.75 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.
  • Vented Box Volume: Rockford Fosgate recommends a vented enclosure with an internal volume of 1.4 cubic feet using a 4" diameter x 13.7" long port tube; this yields a tuning frequency of 42 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 35 Hz).

  • Purchased for the "low profile" depth for limited space installation. The difference in regular depth subs vs. this sub isn't all that significant, but it was enough to properly fit the box. Sound quality is pretty decent, but probably is better in a ported vs. sealed box. Solid subwoofer for the price. No real complaints.

  • My friend made a custom box for my subwoofer and it's really tuned well that it really improved how the sub performs. its a shallow sub so my the box was also not that huge and allows me to save more space
