Stinger RKFR69 FAST Rings Roadkill 6-piece foam baffle kit
Stinger RKFR69 FAST Rings Roadkill 6-piece foam baffle kit consists of six pieces of self-adhesive foam — two center pads, two inner rings, and two outer rings — which install on the speaker frame and behind the speaker, minimizing resonances and improving midbass response.
The center pad mounts behind the speaker to absorb reflections from hard surfa ces inside the car door or most other locations. The inner ring serves as a gasket for mounting the speaker to the metal surface. The outer ring mounts just outside the surround at the outer edge of the speaker, to couple the speaker to the door panel opening.
Stinger’s Roadkill FAST Rings isolate the speaker from the mounting surface and the factory door panel to help eliminate unwanted vibration and noise from the door panels, while increasing midbass response. You’ll have to trim FAST Rings for proper fit.
Each Fast Ring is three concentric foam ovals, a center pad, an inner ring, and an outer ring. They mount around a speaker to improve sound quality. Typical mounting is in a door, but they can be used in almost any speaker location.
The center pad mounts to the inside of the outer door panel, directly behind the speaker. This pad absorbs much of the speaker’s back wave, helping prevent interference with the front wave you want to listen to, and reduces vibration.
The inner ring is sandwiched between the speaker and the mounting surface, acting as a gasket to prevent low frequency (bass) cancellation.
The outer ring mounts to the top of the speaker and is sandwiched between the speaker and door panel. This ring directs all the speaker output into the cabin, and acts as a barrier to interference from rear waves trapped inside the door panel. This ring also helps prevent the door panel from vibrating.
