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. Legendary Products & Support From Authorized Dealers When you choose Frankies BrandBeast, you're choosing quality and performance.

13" Power T2 Single 1-Ohm Subwoofer Glass Fibre/Aramid Honeycomb Sandwich Cone, 4" Edge-Wound Aluminium Voice Coil, Triple-Stack Ferrite Motor, IDHS, 8-AWG Push Spring Terminals. Product Overview The Rockford Fosgate Power T2S1-13 is a 13" effective radiating area Single Voice Coil (SVC) subwoofer with a 1-Ohm impedance from the Power T2 series, designed from the ground up as a high-performance large-format driver. The "13 inches" designation describes the total effective radiating cone area, which includes both the cone and surround assembly the physical basket and cutout dimensions must be confirmed from the official Rockford Fosgate T2S1-13 datasheet. The T2S1-13 introduces several constructions not found elsewhere in this catalogue: a three-layer glass fibre/aramid honeycomb/glass fibre sandwich cone; a single-layer edge-wound aluminium 4" voice coil; a triple-stack segmented ferrite motor structure; a proprietary surround mechanical clamping ring; and 8-AWG custom push spring terminals the heaviest gauge wiring connection in any subwoofer in this batch. The die-cast aluminium frame has integrated heat sink fins and an integrated aluminium IDHS shorting ring.

This is a non-standard format — confirm the physical basket dimensions, cutout diameter, and mounting depth from the official Rockford Fosgate T2S1-13 datasheet before building an enclosure or purchasing a pre-built box. Glass Fibre / Aramid Honeycomb / Glass Fibre Sandwich Cone — A three-layer structural composite cone: glass fibre outer and inner skins provide rigidity, while an aramid honeycomb core (a grid structure of hexagonal cells made from aramid fibre) provides the shear stiffness to resist the out-of-plane forces that cause cone breakup. Aramid honeycomb is used in aerospace and motorsport structural panels. This construction produces a very stiff, low-mass cone for high-excursion bass reproduction. 4" Edge-Wound Aluminium Single Voice Coil — A 4" voice coil is the largest in any subwoofer in this catalogue. Edge-wound construction winds the aluminium conductor wire on its edge (flat-wound), maximising the amount of conductor per unit of axial winding height and increasing the voice coil's force factor (BL). This contributes to the motor's ability to drive the large cone assembly to high excursion levels. Triple-Stack Segmented Ferrite Motor — Three ferrite magnet plates stacked to produce a deep, high-flux magnetic gap suitable for the 4" voice coil. The segmented design uses separate magnet segments rather than a continuous ring — reducing eddy current losses. Ferrite rather than neodymium — selected for the thermal stability and deep magnetic gap appropriate to a sustained high-power, large-format application. Integrated Aluminium IDHS Shorting Ring — The aluminium cap on the pole piece serves dual functions: reducing voice coil inductance variation (distortion reduction) and conducting heat from the magnetic gap into the frame's heat sink fins. Die-Cast Aluminium Frame with Integrated Heat Sink Fins — Direct thermal conduction from the motor gap to the surrounding air through the aluminium frame's heat sink fins — critical for a driver of this power level. Dual Nomex Progressive Spiders — Two progressive-compliance spiders provide controlled suspension across a wide excursion range — the progressive spring rate increases stiffness as the cone approaches excursion limits, protecting the voice coil at high output levels. Proprietary Surround Mechanical Clamping Ring — A mechanical clamping ring is used to secure the surround at the basket edge — a physical fastening method rather than standard adhesive bonding, chosen for long-term durability under the mechanical stress of large-amplitude, high-power cone movement. 8-AWG Push Spring Terminals — The heaviest gauge input terminals in this catalogue — 8-AWG push spring type, accommodating very thick wiring appropriate for the expected high current demand at the T2S1-13's power level. VAST Foam Surround — Injection-moulded foam with VAST geometry for increased effective cone area.

Unlike standard subwoofer diameter measurements (which typically measure the cone only), the T2S1-13's 13" measurement describes the total effective piston area — the combined diameter of both the cone and the surround that contributes to acoustic output. The physical basket is likely larger than 13". Confirm the actual basket diameter and cutout dimensions from the official Rockford Fosgate T2S1-13 datasheet. What is aramid honeycomb and why is it used in the cone? Aramid honeycomb is a grid of hexagonal cells made from aramid fibre (the same material as Kevlar). When sandwiched between glass fibre skins, the honeycomb core provides exceptional structural rigidity against the out-of-plane bending forces that cause cone breakup during high-excursion bass reproduction. The honeycomb structure achieves this with extremely low mass — a key property for a large cone that must move quickly and accurately. What is edge-wound voice coil construction? In a standard voice coil, round wire is wound in circular loops. In an edge-wound (flat-wound) design, the conductor is a flat ribbon wound on its edge — packing more conductor material per unit of winding height. This increases the voice coil's force factor (BL product) and power-handling capacity in the same coil height, contributing to the motor's ability to drive the large 13" cone assembly. What is the power handling of the T2S1-13? Power handling (RMS) is not stated in the supplier description or features list. Confirm from the official Rockford Fosgate T2S1-13 datasheet before purchasing any amplifier or publishing any power matching guidance. What enclosure does the T2S1-13 require? Enclosure type (sealed or vented) is not specified in the supplier data — unlike all other subwoofers in this batch. Confirm from the official Rockford Fosgate T2S1-13 datasheet before building or selecting an enclosure.
