Product Overview

The Rockford Fosgate Punch P3SD4-10 is a 10" 4-Ohm Dual Voice Coil (DVC) shallow subwoofer rated at 300W RMS (600W peak) the most completely specified P3S model in the supplier data. The full specification set includes 83dB sensitivity, 42Hz free-air resonance, 8.1mm Xmax, 89mm (3.50") mounting depth, 230mm (9.06") cutout diameter, and Rockford Fosgate's confirmed enclosure recommendations: 0.5 cu ft (14.1 litres) sealed, 1.0 cu ft (28.3 litres) vented. CEA-2031 compliant. Input terminals are confirmed Dual 10-AWG compression consistent with the P3D2-10 and P2D4-10 spec tables, and confirming that "push terminals" in P3S features lists is a supplier data error.

The 4-Ohm DVC provides wiring options of 2-Ohm (parallel), 8-Ohm (series), or 4-Ohm per coil for bi-amplification no 1-Ohm stability requirement. All confirmed P3S construction applies: anodised aluminium cone and dustcap, M-Roll Santoprene surround, dual linear spider, StampCast basket with spider venting, and diamond-cut cast aluminium trim ring.

Features & Benefits

• 300W RMS / 600W Peak — CEA-2031 — 300W RMS confirmed to the CEA-2031 standard — the same sustained power as the P3SD2-10, delivered in the 4-Ohm impedance format.
• 89mm Mounting Depth — Confirmed — At 3.50" (89mm), the P3SD4-10's mounting depth is confirmed. This is significantly shallower than the standard P3D2-10 (156.8mm) — making the P3SD4-10 suitable for shallow enclosures, rear doors with limited depth, or under-seat installations that the full-depth P3 cannot fit.
• 230mm Cutout Diameter — The confirmed 9.06" (230mm) cutout is slightly smaller than the standard 10" P3 (232mm) — check baffle dimensions against this confirmed figure.
• Confirmed Enclosure Volumes:
  • Sealed: 0.5 cu ft (14.1 litres)
  • Vented: 1.0 cu ft (28.3 litres)
• 83dB Sensitivity — The 83dB @ 1W/1M is slightly lower than the standard P3D4-10 (from the P3D2-10's 82dB reference), consistent with the shallow motor's Fs of 42Hz and Qts of 0.78.
• 42Hz Free-Air Resonance (Fs) — The Fs of 42Hz is higher than full-depth P3 subwoofers (P3D2-10: 26.6Hz), reflecting the shallow motor's stiffer suspension. This affects the enclosure design: the sealed box resonance will be higher than full-depth drivers in the same volume.
• 8.1mm Xmax — 8.1mm of linear peak excursion — less than the 15.2mm of the full-depth P3D2-10, consistent with the shallow motor's reduced excursion range.
• Qts = 0.78 — The higher Qts (versus 0.49 for the full-depth P3D2-10) is characteristic of shallow motor designs. At 0.78, the driver is well-suited to the 14.1L sealed box recommendation; the vented alignment at 28.3L provides additional output at bass frequencies above the port tuning point.
• 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): Separate channels
• Compression Terminals Confirmed — The spec table confirms Dual 10-AWG compression — the correct terminal type across the P2/P3/P3S range. Update all P3S features list descriptions accordingly.
• Anodised Aluminium Cone, M-Roll Santoprene Surround — P3S platform materials confirmed.

Frequently Asked Questions

What are the confirmed enclosure volumes for the P3SD4-10?

Sealed: 0.5 cu ft (14.1 litres); Vented: 1.0 cu ft (28.3 litres). Both are Rockford Fosgate's official confirmed recommendations. Confirm vented port dimensions from the official P3SD4-10 installation guide.

Why is the Fs of the P3SD4-10 higher than a full-depth subwoofer?

An Fs of 42Hz reflects the shallow motor's stiffer suspension — required to control the cone within a reduced excursion range. Full-depth subwoofers with long-travel motors have lower Fs values (e.g. the P3D2-10 at 26.6Hz) because their suspensions are more compliant over a greater travel distance. The higher Fs means the P3SD4-10's useful bass extension begins at a higher frequency than full-depth drivers.

What is the confirmed mounting depth?

89mm (3.50") — confirmed in the specification table.

What does the 230mm cutout mean for enclosure building?

A 9.06" (230mm) cutout is required in the baffle. This is 2mm smaller than the standard 232mm cutout on the full-depth P3D4-10 and P2D4-10 — a meaningful difference if using a pre-drilled enclosure. Confirm the exact cutout before purchase.

Are the terminals push or compression?

The specification table confirms Dual 10-AWG compression terminals — the correct type across the P2, P3, and P3S range. The "push terminals" language in features lists is a consistent supplier data error.
