Description
10" P3 4-Ohm DVC Subwoofer 500W RMS, Anodised Aluminium Cone, VAST, Dual Spider, FlexFit Basket, Extended Pole Piece.
Product Overview
The Rockford Fosgate Punch P3D4-10 is a 10" 4-Ohm Dual Voice Coil (DVC) subwoofer rated at 500W RMS the 4-Ohm variant of the P3 10" platform. Identical construction to the P3D2-10 with the sole difference being 4-Ohm voice coil impedance per coil, providing wiring options of 2-Ohm (parallel), 8-Ohm (series), or 4-Ohm per coil for bi-amplification no 1-Ohm stability requirement. Optimised for sealed and vented enclosures. Sold as an individual unit.
The P3 series introduces the anodised aluminium cone and dustcap of the P3 platform the same premium cone material as the P3D2-10. Full confirmed specifications (sensitivity, Fs, Xmax, enclosure volumes) are not provided in the supplier data for this SKU confirm from the official Rockford Fosgate P3D4-10 datasheet. Physical dimensions on the same 10" P3 platform should be consistent with the P3D2-10 (232mm cutout, 156.8mm mounting depth) but must be independently confirmed before publishing.

Features & Benefits
-
4-Ohm DVC — Broad Amplifier Compatibility:
-
2-Ohm (parallel): Most common configuration
-
8-Ohm (series): For amplifiers with higher minimum impedance
-
4-Ohm per coil (biamp): Each coil to a separate amplifier channel
-
500W RMS — Confirmed 500W RMS — the highest power handling in the Punch series catalogue.
-
Anodised Aluminium Cone and Dustcap — Aluminium's rigidity resists cone breakup at high excursion. Anodising hardens the surface and provides heat conduction from the voice coil. See the P3D2-10 listing for a full explanation of the P3 cone upgrade.
-
Dual Linear Spider — Two spiders for improved suspension compliance and cone control at high excursion levels.
-
VAST — Up to 25% increased effective cone area at the same basket diameter.
-
Hybrid StampCast Basket with FlexFit — Combined rigidity and reduced resonance; FlexFit for non-standard mounting cavity profiles.
-
Nomex® Voice Coil Collar — Thermal and mechanical reinforcement at the voice coil junction — essential for sustained 500W operation.
-
Extended Pole Piece and Bumped Vented Backplate — Extended pole for increased Xmax; vented backplate eliminates air spring compression.
-
Diamond-Cut Cast Aluminium Trim Ring — Premium machined aluminium with grille insert provision.
-
Rubberised Over-Mould — Grip feature on the basket for handling during installation.

Frequently Asked Questions
What is the difference between P3D4-10 and P3D2-10?
Both are identical 10" Punch P3 subwoofers at 500W RMS with the same aluminium cone construction. The sole difference is impedance: P3D4-10 is 4-Ohm per coil (2-Ohm parallel / 8-Ohm series), P3D2-10 is 2-Ohm per coil (1-Ohm parallel / 4-Ohm series). The 4-Ohm DVC avoids the 1-Ohm parallel requirement, providing broader amplifier compatibility.
What enclosure size does the P3D4-10 require?
Full specifications are not provided for the P3D4-10 in the supplier data. Based on the P3D2-10 (same 10" P3 platform): sealed 16.7L / 0.59 cu ft; vented 39.6L / 1.4 cu ft. Confirm with Rockford Fosgate that these volumes apply to the P3D4-10 before building or selecting an enclosure.
What amplifier power is appropriate?
500W RMS at the selected impedance — 2-Ohm (parallel) or 4-Ohm (biamp). Confirm amplifier RMS output at the chosen load.
Is a grille available?
The diamond-cut cast aluminium trim ring accommodates an optional grille insert. Confirm the SKU with Rockford Fosgate.
Does the P3D4-10 have the same aluminium cone as the P3D2-10?
Yes — both use anodised aluminium cone and dustcap, the defining construction upgrade of the P3 series over the P1 and P2 Kevlar paper cones.
