Rockford Fosgate Prime R2S Series 12" Shallow Mount Subwoofer

The Rockford Fosgate Prime R2S 12" shallow-mount subwoofer is built for cars with limited mounting depth, delivering clean, low-frequency bass from a 12" driver designed to install in tight spaces. Its shallow motor assembly and sealed-enclosure focus provide controlled performance where depth is at a premium.

• Size & mounting depth: 12" driver with a shallow 3.602 in (91 mm) mounting depth for installations where depth is constrained.
• Optimized enclosure type: Optimized for sealed enclosures, with sealed box volume listed as 0.9 cu ft (25.4 L) and a vented option of 1.79 cu ft (50.6 L).
• Cone material: Mica-injected polypropylene cone for stiffness and accuracy in bass notes.
• Basket & cooling: StampCast basket with integrated spider venting to help keep the motor cool during demanding bass.
• Motor & assembly: Shallow motor assembly with integrated PVC trim ring and anodized aluminum voice coil former for durable construction.
• Voice coils & terminals: Dual voice coil design with 2" (50 mm) voice coils and dual 12 AWG compression terminals for solid, low-resistance wiring.
• Impedance options: Nominal impedance available as Dual 2-Ohm (two 2-Ω coils) and Dual 4-Ohm (two 4-Ω coils) configurations for amplifier matching.
• Power handling: 250 Watts RMS / 500 Watts max, suitable for sealed-enclosure setups with moderate-to-strong bass demands.
• Physical & electrical specs: Sd 534.8 cm² (0.0830 ft²), Vas 65.4 L, Xmax 10 mm; Fs ~29.7–30.3 Hz; Qts ~0.65–0.66; Qes ~0.71–0.72; Qms ~7.00–9.00; Re ~3.80–6.80 Ω; Le ~4.2 mH.
• Dimensions & weight: Cutout diameter 11.25 in (285 mm); mounting depth 3.602 in (91 mm); magnet weight 51 oz (1.45 kg); shipping weight 12.013 lbs (5.44 kg).
• Displacement: 0.039 cu ft (1.1 L) displacement.
• Connection & compatibility: Dual 12 AWG compression connectors simplify installation and wire sizing for common car audio systems.

Benefits: In a sealed 0.9 cu ft enclosure, the R2S provides focused, punchy bass without excessive enclosure depth, ideal for trunks, under-seat enclosures, or dash-mount installs. The dual voice coil design and multiple impedance options allow flexible amp matching, while the vented spider design helps maintain motor stability during high-output sessions in tight spaces.
