KEY FEATURES
- Diamond Array Pattern Woofer Cone – A textured polypropylene cone design that increases rigidity, reduces distortion, and sharpens sound detail.
- Acoustic Sound Harmonizer – Controls woofer sound waves and filters frequencies through holes in the tweeter panel for a smoother, more natural sound.
- Sound Field Enhancer – The tweeter's unique shape projects sound forward and widens the sound field above 5kHz for a more immersive listening experience.
- Low-Profile Tweeter Design – Tweeter height is minimized so the speaker fits into most OEM/factory mounting locations without modification.
- Black-Painted Yoke and Plate – Improves heat dissipation in the magnetic circuit, lowering voice coil temperature and boosting long-term durability.
- Stress Leveling Points – Structural reinforcement points that increase durability and produce a smoother, more consistent sound response.
- Reduced Chassis Depth – Cuts down speaker weight and simplifies installation in tight factory spaces.
- Shallow Mount, No Cutting Required – Drops into most factory dash, door, and rear-deck locations for a true plug-and-play upgrade.
DESCRIPTION
Upgrade your factory car audio with the Kenwood KFC-C5798RS RS Series 5"x7" 2-way coaxial speakers. Engineered as a direct custom-fit replacement for OEM speakers, this pair delivers 320 watts of peak power and 80 watts RMS per speaker, producing clear, punchy sound without needing an aftermarket amp — though it will run cleanly off one if you have it.
The Diamond Array polypropylene woofer cone fights distortion and adds crisp low-end detail, while the 1-3/16" balanced dome tweeter — powered by Kenwood's Sound Field Enhancer technology — casts a wide, immersive soundstage throughout the cabin. The Acoustic Sound Harmonizer smooths transitions between frequencies for natural, well-balanced audio across the board.
With a shallow 2-1/16" mounting depth and a low-profile tweeter, the KFC-C5798RS drops into most factory 5x7" (and many 6x8") locations with no cutting or modification required, making installation fast and hassle-free.
USES / APPLICATIONS
- Factory speaker replacement in cars, trucks, and SUVs with 5x7" or 6x8" factory speaker openings (dash, front door, or rear deck locations)
- Daily-driver audio upgrade for drivers wanting clearer vocals, tighter bass, and reduced distortion over stock speakers
- Budget-friendly system upgrade for users running a factory head unit or a basic aftermarket stereo without external amplification
- Amplified systems — compatible with small aftermarket amps for users seeking added power and headroom
- DIY installations — ideal for owners who want a straightforward, no-modification speaker swap
