Description
10" 2-Ohm Dual Voice Coil Subwoofer 250W RMS, Mica-Injected Polypropylene Cone, StampCast Basket, 12 AWG Compression Terminals. Sealed and Vented Compatible.
Product Overview
The Rockford Fosgate Prime R2D2-10 is a 10" 2-Ohm Dual Voice Coil (DVC) subwoofer rated at 250W RMS the 2-Ohm variant of the R2 10" platform. The 2-Ohm DVC provides wiring options of 1-Ohm (parallel), 4-Ohm (series), or 2-Ohm per coil for bi-amplification. Optimised for both sealed and vented enclosures. Sold as an individual unit.
Construction is consistent with the R2 platform: 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
-
250W RMS Power Handling — Confirmed 250W RMS.
-
2-Ohm DVC — Three Wiring Configurations:
-
1-Ohm (parallel): Both coils in parallel — confirm amplifier rated stable at 1-Ohm before use
-
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 — Mica particles stiffen the polypropylene cone for reduced flex and more accurate bass reproduction, with polypropylene's moisture resistance.
-
StampCast Basket with Integrated Spider Venting — Venting openings in the basket allow airflow around the spider to cool the motor during sustained operation — Rockford Fosgate notes this feature is "typically reserved for more expensive models."
-
Anodized Aluminium Voice Coil Former — Anodizing increases the emissivity of the aluminium surface for improved heat radiation from the former.
-
12 AWG Compression Terminals — Heavier gauge and more secure than standard push terminals for a 250W installation.
-
Linear Spider with Embedded 16 AWG Tinsel Leads — Consistent compliance across the excursion range; integrated leads reduce flex fatigue failure.
-
Optimised for Sealed and Vented Enclosures — Both enclosure types confirmed.

Compatible With / Goes Well With
Suitable enclosure types:
- Sealed — tight, accurate bass
- Vented — higher efficiency output
Wiring:
- 1-Ohm → parallel (confirm amplifier stability)
- 4-Ohm → series
- 2-Ohm per coil → biamp
Pairs well with:
- Rockford Fosgate T1000-1BDCP, T1500-1BDCP, or T2500-1BDCP mono amplifiers — confirm RMS at selected impedance
Frequently Asked Questions
What is the difference between the R2D2-10 and R2D4-10?
Both are identical 10" Prime R2 subwoofers at 250W RMS with the same construction. The sole difference is impedance: R2D2-10 is 2-Ohm per coil (1-Ohm parallel / 4-Ohm series), R2D4-10 is 4-Ohm per coil (2-Ohm parallel / 8-Ohm series). Select based on your amplifier's stable impedance and preferred wiring configuration.
What are the wiring options for the 2-Ohm DVC?
1-Ohm (parallel — confirm amplifier stability at 1-Ohm), 4-Ohm (series — broadly compatible), and 2-Ohm per coil for bi-amplification.
Is the 1-Ohm parallel wiring safe?
It is safe for the subwoofer. The amplifier must be confirmed rated stable at 1-Ohm — many amplifiers are not. Confirm before using the 1-Ohm configuration.
What enclosure volume is recommended?
Not confirmed in the supplier data. Pull the official Rockford Fosgate R2D2-10 datasheet for sealed and vented volume recommendations.
What amplifier power is appropriate?
250W RMS at the selected wiring impedance. Confirm the amplifier's RMS output at 1-Ohm (parallel) or 4-Ohm before purchasing.
