Description
12" Shallow 2-Ohm DVC Subwoofer 200W RMS, Elevated Shallow Motor Assembly, Mica-Injected Polypropylene Cone, StampCast Basket. Sealed Enclosure Only.
Product Overview
The Rockford Fosgate Prime R2SD2-12 is a 12" 2-Ohm Dual Voice Coil (DVC) shallow subwoofer rated at 200W RMS the 12" 2-Ohm variant of the R2 shallow platform. The larger 12" cone moves more air than the 10" shallow models, providing greater bass output in sealed enclosure applications where space depth is constrained. Optimised for sealed enclosures only. The 2-Ohm DVC provides wiring options of 1-Ohm (parallel), 4-Ohm (series), or 2-Ohm per coil for bi-amplification. Sold as an individual unit.
Construction is consistent across the R2SD range: mica-injected polypropylene cone, anodized aluminium voice coil former, linear spider with embedded 16 AWG tinsel leads, StampCast basket with integrated spider venting, 12 AWG compression terminals, and integrated PVC trim ring.

Features & Benefits
-
12" Shallow Motor Assembly — The 12" shallow driver combines the increased cone area and air-moving capacity of the larger format with the reduced mounting depth of the elevated shallow motor structure — providing more bass output than the 10" shallow models in the same depth-constrained installation space.
-
Sealed Enclosure Only — Optimised for sealed enclosures exclusively. A sealed box produces tight, accurate bass output matched to the shallow motor's design parameters. Do not use in a vented enclosure.
-
200W RMS Power Handling — Confirmed 200W RMS — the same rating as the 10" shallow R2SD models, reflecting the 12" shallow motor's power handling capacity.
-
2-Ohm DVC — Three Wiring Options:
-
1-Ohm (parallel): Both coils in parallel — confirm amplifier is rated stable at 1-Ohm before using this configuration
-
4-Ohm (series): Both coils in series — broad amplifier compatibility
-
2-Ohm per coil (biamp): Each coil to a separate amplifier channel
-
Mica-Injected Polypropylene Cone — Stiffened polypropylene for accurate, clean bass.
-
StampCast Basket with Integrated Spider Venting — Motor cooling via basket ventilation during sustained operation.
-
Anodized Aluminium Voice Coil Former — Improved heat radiation for extended thermal capacity.
-
12 AWG Compression Terminals — Secure wiring connection for 200W RMS operation.
-
Linear Spider with Embedded 16 AWG Tinsel Leads — Consistent compliance; integrated leads reduce flex fatigue.

Compatible With / Goes Well With
Enclosure — sealed only: The R2SD2-12 must be used in a sealed enclosure. Do not install in a vented (ported) enclosure.
Pairs well with:
- Rockford Fosgate T1000-1BDCP or T1500-1BDCP mono amplifiers at the appropriate impedance
- A shallow sealed 12" enclosure to Rockford Fosgate's recommended volume specifications
Frequently Asked Questions
Can the R2SD2-12 be used in a ported enclosure?
No — the R2SD2-12 is optimised for sealed enclosures only. Do not install in a vented enclosure.
What are the wiring options for the 2-Ohm DVC?
1-Ohm (both coils in parallel — requires amplifier rated stable at 1-Ohm), 4-Ohm (both coils in series — broadly compatible), and 2-Ohm per coil for bi-amplification.
What mounting depth does the R2SD2-12 require?
The supplier confirms a shallow motor assembly but the exact mounting depth is not stated. Pull from the official Rockford Fosgate R2SD2-12 datasheet before purchasing for any tight-space installation.
What enclosure volume is recommended?
Not confirmed in the supplier data. Pull from the official Rockford Fosgate R2SD2-12 datasheet for the recommended sealed volume.
Is the 1-Ohm parallel wiring configuration safe?
It is safe for the subwoofer — the driver operates correctly at 1-Ohm. The amplifier must be confirmed rated stable at 1-Ohm. Many amplifiers are not rated for 1-Ohm operation. Always confirm the amplifier's minimum stable impedance before using the 1-Ohm configuration.
