New materials have been developed to make the RF-X lighter than its predecessors but also to maintain its durability – helping to position the RF-X as a versatile product suited for any challenging working environment. It features a four-layer acoustic filter design comprised of the outer vented composite panel, a wool fabric layer, an air gap layer and an inner acoustic foam layer.

This multi-layer design differentiates the RF-X from its competitors by filtering frequencies evenly across the whole spectrum, helping to ensuring that recordings exhibit almost zero sound coloration when using the filter.
