ResoNix Mega CLD Squares: Heavy Duty Sound Deadening Material

ResoNix Mega CLD Squares are the ultimate automotive sound deadening material, designed to provide maximum vibration damping and noise reduction. Measuring 12″ x 12″ for the 5-piece and 20-piece packs, and 18"x32" for the 40 Square foot packs, and featuring a robust 120 mil thick butyl rubber layer combined with a substantial 12 mil aluminum layer, these 132 mil (3.35mm) thick squares offer unparalleled performance.

What makes it different from our standard ResoNix CLD Squares is the thickness of the aluminum constraining layer. On the original ResoNix CLD Squares it is 4-mil thick. On our Mega CLD, we tripled it and stepped it up to 12-mil thick.

Their primary function is to lower structural resonance and road noise, creating a quieter driving experience and providing an ideal foundation for high-quality sound systems. The self-adhesive backing ensures easy application on various surfaces, making them an excellent choice for car enthusiasts, professional audio installers, and DIY hobbyists.

Installing ResoNix Mega CLD Squares is straightforward and effective. For optimal results, ensure the surface is free of dirt, oil, and other contaminants by cleaning it with isopropyl alcohol. Once prepared, peel off the backing and press the squares firmly onto the metal or plastic panels.

These CLD squares boast a remarkable 0.64 composite loss factor on the SAE J1637 Oberst Bar Test, highlighting their superior noise reduction and vibration damping capabilities. Independent testing results have demonstrated that ResoNix offers the highest performing constrained layer damping products on the market, making them a reliable choice for those seeking the best in sound deadening technology.

Available in 5, 10, 20, and 40 square feet packs, ResoNix Mega CLD Squares cater to various project sizes and needs. Not only are they the best constrained layer damper sound deadening material for car audio systems and general automotive noise reduction, but they are also particularly well-suited for van conversions, RVs, motorhomes, and marine applications, but their utility extends to commercial and industrial noise mitigation, HVAC systems, and even aerospace applications.

We get emails regarding this often. The problem is, every application and situation is different. Every panel is different, every car is different, and everyone’s end goals are different. With our ResoNix Sound Deadening Reference Information & Guide section, as well as our ResoNix Sound Deadening Buyers Guide,we try to give you as much information as possible in order to help you make the most informed decision possible. But to make it very quick and simple, in our shop, we almost never do less than 60% coverage on panels that require treatment. This includes door skins and panels, rear decks, roofs, quarter panels, trunks, interior plastic trim, and more. In cases where we are just trying to achieve the best end result possible, we aim for nearly 100% coverage. We figure if we are doing it, we may as well do it once and do it right.
