Rockford Fosgate T2S1-16 Power 16" T2 Single 1-Ohm Subwoofer

16" 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 Terminals.

Product Overview

The Rockford Fosgate Power T2S1-16 is a 16" effective radiating area Single Voice Coil (SVC) subwoofer with a 1-Ohm impedance the larger format counterpart to the T2S1-13, sharing the same Power T2 construction platform. The "16 inches" describes the total effective radiating cone area (cone plus surround assembly), not the conventional cone-only diameter. Physical basket dimensions and cutout must be confirmed from the official Rockford Fosgate T2S1-16 datasheet.

Construction is identical to the T2S1-13: three-layer glass fibre/aramid honeycomb/glass fibre sandwich cone, aluminium dustcap, VAST injection-moulded foam surround with proprietary 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

• 16" Effective Radiating Area — Maximum T2 Output — The largest format in the Power T2 range moves the most air, producing the greatest bass output and lowest frequency extension in the T2 catalogue. Requires the largest enclosure and installation space.
• Glass Fibre / Aramid Honeycomb / Glass Fibre Sandwich Cone — Aerospace-grade structural composite: aramid honeycomb core sandwiched between glass fibre skins for exceptional stiffness-to-mass ratio. Resists cone breakup modes under the high excursion of a large-format 1-Ohm driver.
• 4" Edge-Wound Aluminium Voice Coil — The largest voice coil in any driver in this catalogue, providing maximum magnetic force and thermal capacity appropriate to the T2S1-16's power level.
• Triple-Stack Segmented Ferrite Motor — Three-plate ferrite motor for deep, high-flux magnetic gap; segmented construction reduces eddy current losses in a sustained high-power application.
• Integrated Aluminium IDHS Shorting Ring — Dual function: Faraday ring (reduces inductance variation and distortion) + heat sink (conducts thermal energy through the frame's heat sink fins).
• Die-Cast Aluminium Frame with Integrated Heat Sink Fins — Direct thermal management from motor gap to surrounding air.
• Dual Nomex Progressive Spiders — Two progressive-compliance spiders for controlled excursion with increasing restoring force at the limits of travel.
• Proprietary Surround Mechanical Clamping Ring — Physical surround fastening for long-term durability under sustained large-amplitude cone movement.
• 8-AWG Push Spring Terminals — Heaviest gauge wiring connection in this catalogue, appropriate for the current demands of the T2S1-16's power level.
• VAST Foam Surround — Injection-moulded foam with VAST geometry for increased effective cone area.

Frequently Asked Questions

What is the difference between the T2S1-16 and T2S1-13?

Both are identical Power T2 subwoofers in construction and impedance (1-Ohm SVC). The difference is format: the T2S1-16 has 16" effective radiating area versus the T2S1-13's 13" — producing more air movement, greater bass output, and lower frequency extension. The T2S1-16 requires a larger enclosure and installation space than the T2S1-13.

What does "16 inches effective radiating area" mean?

The 16" measurement describes the total effective piston area — both the cone and the surround assembly combined — rather than the cone diameter only. The physical basket is larger than 16". Confirm basket diameter and cutout dimensions from the official T2S1-16 datasheet.

What is the power handling of the T2S1-16?

Not confirmed in the supplier data. This is a publishability blocker — confirm with Rockford Fosgate from the official T2S1-16 datasheet before purchasing or publishing.

What enclosure does the T2S1-16 require?

Enclosure type (sealed or vented) is not specified. Confirm from the official Rockford Fosgate T2S1-16 datasheet before building or selecting an enclosure.

What amplifier is needed for the T2S1-16?

The amplifier must be rated stable at 1-Ohm for continuous operation — a specific and restrictive requirement. RMS power output must match the T2S1-16's confirmed RMS (TBC). Due to the 1-Ohm impedance and expected high power demand, a high-output mono amplifier such as the Rockford Fosgate T2500-1BDCP should be considered — but confirm RMS matching from the T2S1-16 datasheet first.
