Kenwood KFC-1798RS RS Series 6-3/4" 2-Way Coaxial Speakers
The Kenwood KFC-1798RS is a high-performance 6-3/4" 2-way coaxial speaker system designed to provide clear, dynamic sound with impressive efficiency. Part of the RS Series, these speakers feature a Diamond Array Pattern woofer and Sound Field Enhancer technology to deliver a wider soundstage and more accurate bass response. With a low-profile tweeter and a shallow mounting depth, the KFC-1798RS is an ideal "drop-in" upgrade for a variety of factory door and dash locations.
Elite Performance Features
-
Diamond Array Pattern Woofer: The specialized polypropylene cone increases structural rigidity to reduce distortion and ensure a punchy, accurate low-end response.
-
Acoustic Sound Harmonizer: Strategically placed holes in the tweeter panel control sound waves from the woofer, creating a smoother, more natural tone in the critical 3k–4k Hz vocal range.
-
Sound Field Enhancer: A uniquely shaped tweeter panel that broadens the sound field and creates strong frontward sound projection, especially in frequencies above 5kHz.
-
Factory Location Fit: The 1-3/16" balanced dome tweeter is designed as low as possible (only 1/4" height), allowing these speakers to fit behind factory grilles without modification.
-
Advanced Heat Dissipation: Features a black-painted yoke and plate that release heat efficiently from the magnetic circuit, protecting the voice coil and increasing long-term durability.
-
Optimized Woofer Damper: Stress-leveling points on the damper improve mechanical life and provide a smoother sound response even during high-excursion playback.
