Description
6.75" 2-Way Power Series Component System 80W RMS, Treated Fabric Dome Tweeter, Audiophile External Crossover with 3-Level Attenuation.
Product Overview
The Rockford Fosgate Power T1675-S is a 6.75" 2-way component speaker system rated at 80W RMS. The kit includes two woofers with grilles, two tweeters, dedicated external crossovers, and mounting hardware a complete two-channel front component system with the audiophile crossover quality of the Power series T1T-S tweeter kit built in.
The tweeters are treated fabric dome neodymium ("neo-tweeter") units with integral suspension producing a warm, natural, smooth high-frequency character suited to extended listening. The external crossover uses audiophile-grade components (5% tolerance poly-capacitors and air-core inductors) and provides three levels of tweeter attenuation for level-matching the tweeter to the woofer across different installation positions. On-axis and off-axis tweeter mounting are both supported. The FlexFit basket accommodates a range of OEM mounting cavity profiles, and an OEM adapter plate is included. Woofer cone material, mounting depth, and full technical specifications are not provided in the supplier data pull from the official Rockford Fosgate T1675-S datasheet before publishing.

Features & Benefits
-
80W RMS Power Handling — 80W RMS is confirmed per woofer — providing substantial headroom for amplified installations with the Rockford Fosgate T-series 4-channel amplifiers.
-
Treated Fabric Dome Neodymium Tweeter — The treated fabric dome delivers a warm, natural, and smooth high-frequency character — well suited to extended listening. The integral suspension maintains controlled tweeter compliance. The neodymium motor provides high magnetic flux in a compact, lightweight assembly for high sensitivity and responsive transient performance.
-
External Audiophile Grade Crossover — 5% Poly-Capacitors and Air-Core Inductors — The dedicated external crossover uses 5% tolerance poly-capacitors and air-core inductors for transparent, accurate frequency division. Poly-capacitors provide lower equivalent series resistance than standard electrolytic designs; air-core inductors eliminate magnetic saturation and eddy current losses. The crossover unit must be physically mounted in the door or another accessible location during installation.
-
3 Levels of Tweeter Attenuation — Three selectable attenuation settings adjust the tweeter output level relative to the woofer — compensating for sensitivity differences between the two drivers and for installation positions where the tweeter is closer to the listening position. Specific attenuation values (dB) are not confirmed in the supplier data — pull from the official T1675-S datasheet.
-
On-Axis and Off-Axis Tweeter Mounting — The tweeter can be positioned facing directly toward the listening position (on-axis) for focused treble, or angled (off-axis) for a wider, more diffuse high-frequency spread — both configurations supported without additional hardware.
-
1-3/4" Recessed Tweeter Mount — The recessed mount uses a standard 1-3/4" hole saw for a clean, factory-look flush installation in door panels, A-pillars, and dash trim.
-
FlexFit Basket with OEM Adapter Plate — Non-standard basket geometry for compatibility with a range of OEM door panel mounting cavity profiles, with an adapter plate for additional fitment positions.
-
Butyl Rubber Woofer Surround — UV and heat-resistant synthetic rubber surround for long-term reliability in Australian vehicle conditions.
-
Grilles and Hardware Included — Two woofer grilles and all mounting hardware in the kit.

Frequently Asked Questions
What is included in the T1675-S kit?
The kit includes two 6.75" woofers with grilles, two fabric dome tweeters, external crossovers, an OEM adapter plate, and all mounting hardware — a complete two-channel front component speaker installation.
What are the three tweeter attenuation levels?
The T1675-S crossover provides three selectable attenuation settings for the tweeter output — allowing the tweeter level to be adjusted relative to the woofer to compensate for sensitivity differences and installation position effects. The specific attenuation values in dB are not confirmed in the supplier data — pull from the official Rockford Fosgate T1675-S datasheet.
What type of crossover does the T1675-S use?
An external audiophile-grade crossover using 5% tolerance poly-capacitors and air-core inductors — components chosen for lower signal losses and more accurate frequency division than standard crossover designs. The external crossover must be mounted inside the door or in another accessible location during installation.
What is the woofer cone material in the T1675-S?
Woofer cone material is not specified in the supplier description. Confirm with Rockford Fosgate from the official T1675-S datasheet — noting that the Power series coaxial speakers use a carbon fibre and polypropylene composite cone.
What is an on-axis vs off-axis tweeter configuration?
On-axis positions the tweeter dome facing directly toward the primary listening position for maximum focused high-frequency output. Off-axis angles the tweeter away from the direct listening axis for a wider, more diffuse high-frequency spread across the cabin. Both configurations are supported by the included mounting hardware.
