Layers
of Performance

       The two layers of Hydrophobic Melamine foam are arguably the most important. Not only is it an excellent acoustic absorber, but it is also an aerospace-grade thermal insulator. This product is quite literally used on the tips of rockets for thermal insulation. Anyways, for car audio applications, Lockout will be used inside of door cavities, stuck to the outer door skin, (AFTER a CLD is applied, preferably ResoNix CLD Squares). In this scenario, the Hydrophobic Melamine is being used to absorb acoustic energy from the rear wave of the door-mounted midbass driver. This will reduce the amount of energy that reaches the outer door skin, which creates the most resonance in the door of a vehicle. This will also in turn reduce the amount of acoustic energy that can be reflected back and transferred into the inner door skin which will cause further resonance but also rattles.

       Being used in a headliner/roof will offer some other benefits.  As of writing this (January 26th, 2023), we haven’t been able to compare ResoNix Lockout to ResoNix Fiber Mat in a roof installation. The Hydrophobic Melamine will also come in handy for those building out vans for camping and travel purposes. Not only will it drastically lower the noise floor in the vehicle, but it will also help keep heat out in the hot summer months, and help trap heat in during the winter, making your home on wheels more comfortable and efficient.

But what about water? Isn’t open-cell foam problematic in an automotive environment?

       Now, melamine being an open-cell foam would normally be problematic for automotive installations. But for ResoNix Lockout, a proprietary process is used to treat our Melamine to make it fully hydrophobic, inside and out. This isn’t some cheap spray you can buy at Home Depot that will wear off in 4 months. We can guarantee that this product will never absorb water for the life of your vehicle. Due to this, it can be used without worry in door cavities, on the underside of hoods, and even on underbody pans and other places on the outside of the vehicle. No matter what you throw at it, ResoNix Lockout can handle it.

       A mouthful, I know. But what this is, while the first time we have seen it used in aftermarket automotive sound treatment products, is pretty self-explanatory. This top layer of ResoNix Lockout is a polyester fabric that is oil and water resistant, and helps achieve two different goals. First, it provides protection and some strength for the Hydrophobic Melamine foam to help protect it from rips and tears, but it also helps tune the acoustic absorption properties of ResoNix Lockout by providing a specific acoustic resistance which helps us target even better low-frequency acoustic absorption which is perfect for when using it in midbass and subwoofer applications, as well as road/engine noise absorption. This fabric facing, just like the Hydrophobic Melamine, is also extremely heat resistant and can be used just about anywhere in or on a vehicle.

       As with the rest of our products, the adhesive we have chosen for ResoNix Guardian and Lockout is the best for the application. It is able to work with and adhere to Hydrophobic Melamine while also being able to stick to pretty much any clean surface and can handle an extremely wide range of temperatures. This allows for an easy installation of ResoNix Lockout without having to worry about long term reliability.

Where Should ResoNix Lockout Be Used?
What Locations Benefit From A Sound Absorber In A Car?

The most common use and location of ResoNix Lockout would be inside of the door cavity on the outer door skin in sound systems with door-mounted midbass drivers. The use of Lockout here will help improve overall midbass response and lower distortion. The Hydrophobic Melamine layer will absorb sound energy produced by the rear wave of the door-mounted midbass driver, therefor lowering the amount of energy that can cause the outer and inner door skins to resonate, and will also help dissipate the energy faster, resulting in a more accurate impulse response. This translates into better, more accurate midbass from your door-mounted midbass drivers. That said, if you want the very best performance, look into using our ResoNix Guardian product, which takes performance in this domain to the top level.

 

Headliners will also be a common location for ResoNix Lockout since it is an excellent sound absorber and thermal insulator. The Hydrophobic Melamine in ResoNix Lockout will take care of sound absoption and do very well at reducing wind noise. ResoNix Lockout is great to use for those who are trying to reduce sound and thermally insulate while trying to keep a uniform look, such as in applications where the vehicle doesn’t have a headliner to hide it. For those that have a headliner to hide it, ResoNix Fiber Mat 45 will be a much simpler and more effective product to install here. Note: This product is not very compressible so you must have adequate space to install it above the headliner. If you want a product that also offers the additional performance of a noise barrier, be sure to check out ResoNix Guardian.

Much like doors, the use of ResoNix Lockout will be beneficial to reduce both structural and airborne resonance. While not as important in a subwoofer enclosure since it should be sturdy and non-resonant from the start, installing ResoNix CLD Squares, then ResoNix Guardian, and then ResoNix Fiber Mat 45 is our recommended go-to for those trying to build the ultimate subwoofer enclosure with no compromises. This will result in an enclosure that has further reduced structural resonance due to the lowered and quicker-absorbed sound energy.

 

ResoNix Lockout is a great product for your van build. It takes care of 2 major issues that you run into while treating a van; sound absorption and thermal insulation. The Hydrophobic Melamine is a great thermal insulator and acoustic absorber.
