Upgrade your car audio system with the Edge SR65-4K Foam Speaker Ring Enhancer Kit. Designed specifically for 6.5" speakers (also fits 6" and 6.75"), these high-rebound foam rings seal your speakers against door panels, eliminating sound lost in door cavities and directing music straight into the cabin. The result? Cleaner mids, punchier bass, and a more immersive listening experience. Made from durable, weather-resistant polyurethane foam with strong self-adhesive backing, installation takes just minutes — peel, stick, and go. Whether you're replacing worn-out baffles or building a new system, the SR65-4K delivers professional-grade sound isolation in a simple DIY package. 4 rings included (enough for 2 speakers).



•       Perfect Fit for 6.5" Speakers: Each foam ring measures 190mm (7.5") outer diameter, 142mm (5.6") inner diameter, and 25mm (0.98") height. Designed to fit most 6", 6.5", and 6.75" vehicle speakers — cars, trucks, SUVs, and marine applications.

•       Eliminate Lost Sound & Seal Your Speakers: These foam fast rings seal your speakers against interior door panels and mounting surfaces, directing sound straight into the cabin instead of leaking into door cavities. No more wasted sound — every note reaches your ears.

•       More Fulfilling, Punchier Bass: Speaker isolation pads prevent sound quality diffusion, absorb door echo and vibration, and enhance overall speaker performance. Truly enhances your audio by controlling lost sound and delivering cleaner, tighter bass.

•       Durable High-Rebound Foam Construction: Made from heavy-duty polyurethane polymers with high density and high elasticity. Weather-resistant and stable — unaffected by high or low temperatures. Provides consistent sound insulation performance that lasts.

•       Easy DIY Installation – Self-Adhesive Design: Comes with strong double-sided adhesive backing. Simply peel, align, and stick to your speaker frame. Includes both outer rings and inner circles for complete coverage. Once installed, they won't fall off — even in hot or humid conditions.

• 4-Piece Kit for Two Speakers: This kit includes 4 foam rings — enough for a pair of 6.5" speakers (left and right). Perfect for upgrading your car's front or rear door speakers without buying extra materials.
