6.5 Inch Speaker Foam Rings – High Rebound Acoustic Foam Bass Blocker Kit, Self-Adhesive Car Door Speaker Baffles Enhancer for 6”, 6.5”, 6.75” Vehicle Speakers - 4 Pack

• ? Optimized for 6”–6.75” Speakers – Outer diameter: 7.5 inches (190mm), inner diameter: 5.6 inches (142mm), height: 1 inch (25mm). Perfect fit for most 6-inch, 6.5-inch, and 6.75-inch car door speakers, coaxial speakers, and component systems.
• ? Eliminates Sound Loss & Improves Bass – These foam rings create a tight acoustic seal between the speaker and door panel, directing sound into the cabin instead of leaking into door cavities. Reduces echo, prevents sound diffusion, and delivers fuller, punchier bass.
• ? High-Density, Weather-Resistant Foam – Made from heavy-duty polyurethane polymer with high rebound and compression resistance. Stable across extreme temperatures – won’t harden in winter or soften in summer. Ensures long-lasting acoustic performance.
• ? Easy Peel-and-Stick Installation – Strong self-adhesive backing on each ring. Simply clean the mounting surface, peel off the protective film, and press firmly onto the speaker frame or door panel. No tools or extra glue required.
• ? Wide Application for Car Audio Upgrades – Ideal for car door speakers, rear deck speakers, marine audio, and even home theater speaker baffles. An affordable way to enhance sound staging and reduce unwanted resonance.
