Rockford Fosgate R2SD4-12 Prime 12" 4-Ohm DVC Shallow Subwoofer (R2SD412)
Rockford Fosgate R2SD4-12 Prime 12" 4-Ohm DVC Shallow Subwoofer
Shallow Mount Design
The Rockford Fosgate R2SD4-12 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 mono load, when wired in series it presents an 8-ohm mono 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 0.9 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 for all types of music.Vented Box Volume
Rockford Fosgate recommends a vented enclosure with an internal volume of 1.79 cubic feet using a 4" diameter x 11.8" long port tube; this yields a tuning frequency of 40 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).Please consult your amplifier owner's manual for the lowest recommended impedance for the Rockford Fosgate R2SD4-12
