Description
6.75" Shallow 2-Way Power Series Coaxial 75W RMS, Pole-Mounted Aluminium Dome Tweeter, Carbon Fibre Composite Cone, ICC Crossover, Grilles Included.
Product Overview
The Rockford Fosgate Power T1675 is a 6.75" 2-way coaxial speaker rated at 75W RMS a shallow-depth design confirmed in the supplier description, enabling installation in door panels and cavities where a standard-depth 6.75" speaker would not fit without modification. The kit includes grilles, an OEM adapter plate, integrated concealed crossovers, and all mounting hardware.
The T1675 uses the Power series construction platform: a carbon fibre and polypropylene injection-moulded composite cone, a pole-mounted aluminium dome tweeter with polyurethane suspension, a butyl rubber surround, a FlexFit basket for OEM cavity compatibility, and an ICC (Integrated Concealed Crossover). The pole-mounted tweeter sits elevated above the woofer cone on a central post, improving high-frequency dispersion compared to a flush-mounted design. Full technical specifications exact mounting depth, impedance, sensitivity, frequency response, and crossover details are not provided in the supplier data.

Features & Benefits
-
Shallow Mounting Depth — Specifically described as shallow-depth, the T1675 is designed for door panels and cavities with limited depth clearance behind the mounting surface. The exact mounting depth in millimetres is not confirmed in the supplier data — pull from the official Rockford Fosgate T1675 datasheet before purchasing for any depth-constrained installation.
-
75W RMS Power Handling — 75W RMS is confirmed per speaker, providing substantial headroom for amplified installations with Rockford Fosgate's T-series 4-channel amplifiers.
-
Pole-Mounted Aluminium Dome Tweeter — The tweeter is elevated above the woofer cone on a central pole, improving high-frequency dispersion by placing the dome away from the acoustic interference zone of the woofer cone face. The aluminium dome with polyurethane suspension delivers fast, detailed treble with controlled resonance damping.
-
Carbon Fibre and Polypropylene Composite Cone — The injection-moulded composite combines carbon fibre's high stiffness and low mass with polypropylene's moisture resistance — producing a lighter, stiffer diaphragm than standard polypropylene for more accurate midrange reproduction.
-
ICC — Integrated Concealed Crossover — Crossover circuitry built directly into the tweeter assembly eliminates any external crossover component. Crossover slope and frequency are not confirmed in the supplier data — pull from the official datasheet.
-
FlexFit Basket with OEM Adapter Plate — Non-standard basket geometry for OEM cavity compatibility with an included adapter plate for additional fitment positions.
-
Butyl Rubber Surround — UV and heat-resistant synthetic rubber for long-term reliability in Australian vehicle environments.
-
Grilles and Hardware Included — Complete kit for a finished installation.

Frequently Asked Questions
What does "shallow mounting depth" mean for the T1675?
Shallow mounting depth means the speaker extends less distance behind the mounting surface than a standard-depth 6.75" speaker. This is critical for door panel installations where the inner door structure limits the available cavity depth. The exact T1675 mounting depth must be confirmed from the Rockford Fosgate datasheet before purchasing for any depth-constrained installation.
What is a pole-mounted tweeter and what advantage does it provide?
A pole-mounted tweeter is elevated above the woofer cone on a central post, placing the dome in a position where high-frequency output is less affected by acoustic interference from the woofer cone surface. This produces a wider, more even treble spread across the listening area.
Are grilles included with the T1675?
Yes — grilles are confirmed in the product description alongside adapter plates and mounting hardware.
What technical specifications are confirmed for the T1675?
75W RMS power handling, shallow mounting depth, pole-mounted aluminium dome tweeter with polyurethane suspension, carbon fibre composite cone, butyl rubber surround, FlexFit basket, ICC crossover, OEM adapter plate, grilles included, and sold as a pair are confirmed. Impedance, sensitivity, exact mounting depth, frequency response, and crossover specification must be pulled from the official Rockford Fosgate T1675 datasheet before publishing.
What OEM adapter plate formats are included?
The supplier description confirms adapter plates are included but does not specify oval formats. Confirm the specific adapter plate formats included with Rockford Fosgate or from the official T1675 datasheet.
