Description
10" 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 R2SD2-10 is a 10" 2-Ohm Dual Voice Coil (DVC) shallow subwoofer rated at 200W RMS designed specifically for tight-space installations where a standard-depth subwoofer cannot be accommodated. The shallow motor assembly uses an elevated motor structure that reduces the speaker's mounting depth while maintaining effective bass output.
The R2SD2-10 is optimised for sealed enclosures only unlike the standard R2D series which suits both sealed and vented designs. The shallow motor configuration is best matched to the controlled acoustic environment of a sealed box. The 2-Ohm DVC provides wiring options of 1-Ohm (parallel), 4-Ohm (series), or 2-Ohm per coil for bi-amplification. 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. Sold as an individual unit.

Features & Benefits
-
Shallow Motor Assembly — The elevated motor structure reduces the overall depth of the subwoofer behind the mounting plane — enabling installation in locations where a standard-depth subwoofer would not physically fit. Under-seat, behind rear seats, and in custom enclosures with limited depth clearance are the primary applications.
-
Sealed Enclosure Only — The R2SD2-10 is optimised exclusively for sealed enclosures. The shallow motor configuration and reduced Xmax compared to standard-depth subwoofers are best matched to the controlled, predictable acoustic loading of a sealed box. A sealed enclosure produces tight, accurate bass with a gradual roll-off — well suited to music where bass clarity is the priority.
-
200W RMS Power Handling — 200W RMS confirmed — appropriate for sealed shallow-mount subwoofer installations paired with a matched mono amplifier.
-
2-Ohm DVC — Three Wiring Configurations:
-
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 bass reproduction with moisture resistance.
-
StampCast Basket with Integrated Spider Venting — Ventilation openings cool the motor during sustained operation.
-
Anodized Aluminium Voice Coil Former — Improved heat radiation for extended thermal capacity in a compact motor assembly.
-
12 AWG Compression Terminals — Secure, low-resistance wiring connection for 200W RMS operation.
-
Linear Spider with Embedded 16 AWG Tinsel Leads — Consistent compliance and integrated leads for reduced flex fatigue.

Compatible With / Goes Well With
Enclosure type — sealed only: The R2SD2-10 must be used in a sealed enclosure. Do not install in a vented (ported) enclosure — the shallow motor design is not optimised for vented loading.
Pairs well with:
- Rockford Fosgate T1000-1BDCP or T1500-1BDCP mono amplifiers at the appropriate impedance
- A shallow sealed 10" enclosure designed to the Rockford Fosgate recommended volume for the R2SD2-10
Frequently Asked Questions
Can the R2SD2-10 be used in a vented (ported) enclosure?
No — the R2SD2-10 is optimised for sealed enclosures only. The shallow motor assembly and its reduced excursion compared to standard-depth subwoofers are specifically matched to sealed box loading. Installing it in a vented enclosure will not produce correct performance and may result in driver damage at higher output levels.
What mounting depth does the R2SD2-10 require?
The supplier confirms this is a shallow-mount subwoofer with an elevated motor structure that reduces mounting depth — but the exact depth in millimetres or inches is not confirmed in the supplier data. Pull the official Rockford Fosgate R2SD2-10 datasheet for the confirmed mounting depth before purchasing for any depth-constrained location.
What are the wiring options for the 2-Ohm DVC?
The 2-Ohm DVC provides three configurations: 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 sealed enclosure volume is recommended?
Enclosure volume for the sealed configuration is not confirmed in the supplier data. Pull the official Rockford Fosgate R2SD2-10 datasheet for the recommended net internal volume.
How does the shallow design affect bass performance?
A shallow motor assembly achieves reduced depth by elevating the motor relative to the cone — this reduces the driver's linear excursion (Xmax) compared to a full-depth subwoofer of equivalent size. The trade-off is lower maximum output below the sealed enclosure resonance frequency, which is why the R2SD2-10 is rated at 200W RMS rather than the 250W of the standard R2D series. For most under-seat and shallow enclosure applications, the output is sufficient for satisfying bass at normal listening levels.
