Ideal For Acoustic Coupling For Speakers Behind Grilles
ResoNix CCF Strips are a simple but highly effective tool for improving the performance of your car’s audio system. Designed to create a proper acoustic seal between the speaker and the grille opening or panel in front of it, these strips help direct all acoustic energy into the cabin instead of letting it escape behind door or dash panels. This results in higher output, reduced resonance, meaning less distortion and more accurate sound reproduction.
Each strip is 1 inch thick, 30 inches long, and tapers from 0.75 inches wide at its thickest to 0.5 inches at its narrowest. This makes it easy to bend, shape, and install around nearly any speaker, from 1 inch tweeters to large 9.5 inch midbass drivers. The built-in automotive-grade acrylic adhesive ensures a strong, long-lasting bond to speaker frames, baffles, or surrounding surfaces.
What sets ResoNix CCF Strips apart is the use of our high-performance closed cell foam. This is the same foam used in our CCF Decoupler 3S & 7S, which was selected specifically for its ideal compression deflection and compression set characteristics. It provides the right amount of stability to create an effective seal while remaining compliant enough to conform to irregular or contoured surfaces. It does not absorb moisture and holds up over time, even under pressure and extreme automotive temperatures.
Other options on the market, such as silicone baffles and open-cell foam rings, may sound appealing for ease, other features, or price but fall short in real-world applications. Silicone baffles usually fail to make a proper seal due to their shape and lack of ability to apply pressure to create an actual seal, and open-cell foams allow air to pass through, defeating the purpose entirely. ResoNix CCF Strips are designed without gimmicks, using real engineering and real materials to solve a real problem.
If you care about getting the most out of your speakers and want to avoid throwing away output and adding distortion, ResoNix CCF Strips are one of the simplest and most effective upgrades you can make. Proudly made in the USA and now sold as individual units, this is the quality solution that serious installers rely on.
