The Stinger RKFR6 Roadkill 6 inch foam speaker rings are a sealing kit designed to create a tighter acoustic seal between 6 inch speakers and the mounting surface, improving mid-bass response and reducing unwanted reflections and resonance.

Each kit contains two foam rings per pair with a two-layer design, self-adhesive backing, and high-density weather-resistant foam for durable installation in doors and panels. Designed for use with 6 inch coaxial and component speakers to maximize acoustic coupling.
