Rockford Fosgate T2S2-13 Power 13" T2 Single 2-Ohm Subwoofer

13" Power T2 Single 2-Ohm Subwoofer Glass Fibre/Aramid Honeycomb Sandwich Cone, 4" Edge-Wound Aluminium Voice Coil, Triple-Stack Ferrite Motor, IDHS, 8-AWG Terminals.

Product Overview

The Rockford Fosgate Power T2S2-13 is a 13" effective radiating area Single Voice Coil (SVC) subwoofer the 2-Ohm variant of the T2S1-13 platform. The construction is identical to the T2S1-13 with the sole difference being the 2-Ohm voice coil impedance, which provides broader amplifier compatibility than the 1-Ohm T2S1-13.

All confirmed T2 platform construction applies: three-layer glass fibre/aramid honeycomb/glass fibre sandwich cone, aluminium dustcap, VAST injection-moulded foam surround with mechanical clamping ring, dual Nomex progressive spiders, die-cast aluminium frame with integrated heat sink fins, single-layer edge-wound aluminium 4" voice coil, triple-stack segmented ferrite motor, integrated aluminium IDHS shorting ring, vented pole piece, and 8-AWG push spring terminals.

Features & Benefits

• 13" Effective Radiating Area — Total effective piston area (cone plus surround). Physical basket and cutout dimensions must be confirmed from the official T2S2-13 datasheet.
• 2-Ohm SVC — Broader Amplifier Compatibility Than T2S1-13 — A 2-Ohm SVC is supported by a wider range of high-output mono amplifiers than the 1-Ohm T2S1-13, which requires amplifiers specifically rated stable at 1-Ohm. Two T2S2-13 units in series = 4-Ohm; two in parallel = 1-Ohm (confirm amplifier stability before using 1-Ohm parallel).
• Glass Fibre / Aramid Honeycomb / Glass Fibre Sandwich Cone — Aerospace-grade structural composite for maximum stiffness and minimum mass — identical construction to T2S1-13.
• 4" Edge-Wound Aluminium Voice Coil — Largest voice coil in the catalogue; flat-wound conductor for maximum BL product and thermal capacity.
• Triple-Stack Segmented Ferrite Motor — Deep, high-flux magnetic gap for the 4" voice coil; segmented construction reduces eddy current losses.
• IDHS Aluminium Shorting Ring — Dual-function: distortion reduction (inductance variation) and heat conduction through the frame's heat sink fins.
• Die-Cast Aluminium Frame with Integrated Heat Sink Fins — Direct thermal management from motor gap to air.
• Dual Nomex Progressive Spiders — Progressive compliance for controlled high-excursion operation.
• Proprietary Surround Mechanical Clamping Ring — Long-term surround durability under sustained large-amplitude movement.
• 8-AWG Push Spring Terminals — Heaviest gauge wiring in this catalogue.

Frequently Asked Questions

What is the impedance of the T2S2-13?

The product title states 2-Ohm and the SKU designation "S2" indicates Single 2-Ohm. The product description text states "a single 1-ohm voice coil" — this appears to be copied from the T2S1-13 (1-Ohm) description without updating the impedance reference. Confirm the correct impedance with Rockford Fosgate before purchasing.

What is the difference between T2S2-13 and T2S1-13?

Assuming the T2S2-13 is the 2-Ohm variant as indicated by the title and SKU: both are identical 13" T2 subwoofers in construction. The T2S2-13's 2-Ohm impedance suits a broader range of mono amplifiers than the T2S1-13's 1-Ohm, which requires amplifiers specifically rated stable at 1-Ohm.

What is the power handling?

Not confirmed in the supplier data — same blocker as T2S1-13. Confirm from the official T2S2-13 datasheet.

What enclosure is required?

Enclosure type not specified. Confirm from the official T2S2-13 datasheet.

What amplifier is appropriate?

Amplifier guidance cannot be published until the impedance conflict is resolved and the RMS power is confirmed. Confirm both with Rockford Fosgate before purchasing.
