Stinger RKFR6 6.5" RoadKill Fast Rings

Stinger RKFR6 Roadkill Fast Rings 6.5 Inch Speaker Vibration Damping Kit with Outer Rings, Gaskets and Backwave Pads

The RKFR6 from Stinger is a Roadkill Fast Rings kit for speakers up to 6.5 inches, designed to improve speaker frequency response and bass output by addressing the three key areas where speaker performance is lost at the mounting point. Each kit includes two speaker outer rings, two speaker gasket rings, and two speaker backwave pads, covering a pair of speakers.

Product overview

Speaker performance in a vehicle door or parcel shelf is significantly affected by the mounting environment. Open cavities behind the speaker allow sound waves to escape and cancel, while gaps between the speaker and mounting surface reduce efficiency and alter frequency response. The RKFR6 addresses all three of these issues with a three-ring approach that treats the speaker at the gasket, surround, and backwave level simultaneously.

The outer ring sits between the door card or parcel shelf material and the metal or plastic mounting surface, stopping speaker cancellation caused by open cavities. The gasket ring seals the gap between the speaker frame and the mounting surface, and the backwave pad treats the rear of the speaker cone to reduce unwanted resonance. All three rings use self-adhesive backing and can be trimmed to size with scissors or a knife if the vehicle application requires it.

Features and benefits

Three-ring approach for complete speaker mounting treatment: The kit addresses speaker performance at three points simultaneously: the outer ring stops cancellation from open door or parcel shelf cavities, the gasket ring seals the speaker-to-mount interface, and the backwave pad reduces rear cone resonance.

Improved frequency response and bass output: By sealing gaps and stopping cancellation at the mounting point, the RKFR6 improves the speaker's ability to project audio into the cabin, delivering better frequency response and more effective bass output without any additional amplification.

Self-adhesive backing for easy installation: All three ring types use a self-adhesive backing. Clean the mounting surface, peel the backing, and press into position. Each ring can also be trimmed to size with scissors or a knife if required for the vehicle application.

Suits speakers up to 6.5 inches: The RKFR6 is designed for speakers up to 6.5 inches in diameter, covering the most common speaker size used in factory and aftermarket door and parcel shelf positions.

Sold as a pair: Each kit covers two speakers, including two outer rings, two gasket rings, and two backwave pads, providing everything needed to treat a pair of speakers in a single purchase.

Frequently asked questions

What do Roadkill Fast Rings actually do?
Fast Rings treat the speaker at three mounting points to improve sound performance. The outer ring stops cancellation from open door or parcel shelf cavities. The gasket ring seals the gap between the speaker frame and mounting surface. The backwave pad reduces unwanted resonance from the rear of the speaker cone. Together, the three rings improve frequency response and bass output without additional amplification.

Will the RKFR6 fit my speakers?
The RKFR6 is designed for speakers up to 6.5 inches in diameter. Each ring can also be trimmed to a smaller size with scissors or a knife if required for a specific vehicle application. Contact us if you are unsure whether the RKFR6 suits your speaker size.

Does the RKFR6 kit cover one speaker or two?
The RKFR6 is sold as a pair and covers two speakers. Each kit includes two outer rings, two gasket rings, and two backwave pads.

Do I need to use all three ring types together?
For the best result, all three ring types should be used together as part of the complete three-ring approach. Each addresses a different aspect of speaker mounting performance, and using all three delivers the most significant improvement in frequency response and bass output.

Are Fast Rings compatible with Roadkill Expert sound damping matting?
Yes. Fast Rings and Roadkill Expert are complementary products. Applying Roadkill Expert to the door cavity before installing the Fast Rings and speakers delivers the most complete noise and performance improvement result.
