ResoTech™ Pro 1-Inch Melamine Speaker Damping Foam with PSA

ResoTech™ Pro 1-Inch Melamine Speaker Damping Foam with pressure sensitive adhesive. Two 12-inch x 12-inch pieces. Melamine has been the hidden gem used by high-end audio engineers for its unmatched damping properties and its ultra light weight composition. Zap Acoustics brings you their ResoTech™ Pro 1-inch melamine damping foam so you can upgrade your own speaker enclosures with the same professional acoustic damping material used by high-end speaker manufacturers. This is a top-tier sound absorbing material that outperforms all similar thickness foam on the market today. Unlike other foams, ResoTech™ Pro features an unmatched 99% open-cell structure that maximizes sound absorption without taking up any noticeable internal volume from your speaker cabinet. It's an ultra-lightweight foam designed specifically to trap unwanted back-wave energy from woofers and midranges inside your speaker cabinet. By completely absorbing that rear-wave energy from your drivers, it prevents muddy mid-tones and distortion from bouncing back through the woofer cone. The result is a better transient response, an incredibly clean midrange, and a tighter, more defined low-end. ResoTech™ Pro damping foam cuts easily with a razor blade or scissors for fast installation. The heavy-duty adhesive backing allows you to permanently mount it to the internal cabinet walls without any extra glue or special tools. Why choose Resotech™ Pro Melamine: True Open-Cell Performance: Unmatched with an over 99% open cell network that traps internal reflections, preventing muddy midrange distortion from bleeding back through your driver cones. It's incredibly effective at killing the boxy or hollow sound caused by midrange frequencies echoing off the rear wall. No Mess, Peel-and-Stick Install: Industrial-grade pressure-sensitive adhesive backing sticks instantly and permanently to MDF, Baltic birch, and plastics. Zero-Sag Stability: Feather-light but structurally rigid means it's easy to cut and won't compress or sag over time. Studio Grade & Fire Safe: Class A fire-rated and highly resistant to temperature fluctuations, ensuring total peace of mind inside high-powered active or passive builds. Long-Term Durability: A high quality German product that's resistant to moisture, mold, and crumbling.
