ResoNix CCF Strips - Foam Speaker Ring Strips For Speaker-To-Panel Coupling

ResoNix CCF Strips are the best solution for sealing midbass and midrange speakers to factory or aftermarket grilles. By creating a proper seal, they ensure all of your speaker’s output reaches the cabin instead of leaking behind trim panels. This increases output and lowers distortion caused by resonance. Each strip is 30″ long, 1″ tall, and 0.75–1.0″ wide. Sold individually. A quantity of 3 will net you 3 individual strips.

ResoNix CCF Strips - Foam Speaker Ring Strips For Speaker-To-Panel Coupling Specifications

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.

  • 1″ thick closed-cell foam
  • 30″ long (suitable for speakers up to 9.55″ diameter
  • Width tapers from 0.75″ (widest) to 0.5″ (narrowest)
  • Automotive-grade acrylic peel-and-stick adhesive backing
  • Compression deflection and compression set optimized for acoustic sealing
  • CCF construction: does not absorb water or retain moisture
  • Flexible enough to contour around tight curves and odd panel shapes
  • Resistant to heat, cold, and typical automotive chemical exposure
  • Proudly made in the USA

       Each strip is sold individually and measures 30 inches in length, which is enough to wrap one speaker up to 9.5 inches in diameter. For most standard car audio installations that feature a grille in front of your speakers, you'll need one strip per midbass speaker, and can usually get away with one strip per midrange speaker pair. Measure the outer diameter of your speaker frame or baffle opening to confirm how much you'll need, and add a little extra if you plan to double-layer or make custom shapes.

ResoNix CCF Strips - Foam Speaker Ring Strips For Speaker-To-Panel Coupling vs. Others

Others
Superior Foam Quality

High-performance closed-cell foam with proper support and compliance

Details

Superior Foam Quality

       ResoNix CCF Strips are made from the same high-quality closed-cell foam used in our CCF Decoupler 3S and 7S. This foam was chosen for its ideal compression deflection and compression set characteristics, meaning it stays soft enough to seal against panels and grilles, but firm enough to direct acoustic energy effectively. In contrast, other foam products often use low-density, overly stiff, or overly soft materials that either fail to create a proper seal or break down over time. Ours doesn’t absorb moisture, stays intact under pressure, and lasts long term, even in extreme environments.

Proper Seal Every Time

Creates real acoustic seals unlike gimmick products

Details

Proper Seal Every Time

       Unlike silicone baffles or open-cell foam rings, ResoNix CCF Strips are designed to actually do the job they claim to do. Silicone baffles cannot properly press and seal against the grille due to their floppy shape and lack of structure. Worse, their built-in rain guards restrict airflow, which introduces resonance in the midbass driver's response, measurable as impedance spikes. Open-cell foams allow air to travel right through, which defeats the entire purpose of sealing in the first place. ResoNix CCF Strips don’t play pretend, they genuinely make real, effective seals that force all the sound out into the cabin where it belongs.

Built to Withstand the Environment

Foam and adhesive that can handle real-world use

Details

Built to Withstand the Environment

       A lot of other foam rings either come loose, melt, absorb moisture, or dry rot after a few summers of use. ResoNix CCF Strips are made with an automotive-grade acrylic-based adhesive that sticks and stays, even under high heat, humidity, and pressure. The foam does not absorb water and won’t degrade like cheap materials found in knock-off rings or low-effort designs. Whether you’re in Arizona or Alaska, our materials hold up and perform without fail.

Easy to Shape & Install

Contoured design simplifies install around any speaker

Details

Easy to Shape & Install

       Each strip is 30 inches long, 1 inch thick, and tapers from 0.75 inches wide to 0.5 inches wide, allowing it to flex and bend easily around any speaker shape. Whether you’re working with a tiny tweeter or a 9.5-inch midbass driver, it conforms naturally without the need to cut weird angles, layer materials, or force a pre-molded ring to fit. Most other foam rings are fixed sizes and shapes, requiring trimming, stacking, or awkward compromises. Our design just works.

Fits More Sizes | One strip works on everything from tweeters to large mids

Fits More Sizes

       ResoNix CCF Strips are not cut for a specific speaker size. Each 30-inch strip can wrap around any speaker from a 1-inch tweeter to a 9.5-inch midbass driver. There’s no need to buy different products for different applications, no need to trim or modify to get proper coverage, and no need to guess if the product will actually fit. It’s a one-size-fits-all solution that’s flexible enough to do it right.
