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.
How Does it Work?
When you put a microphone in front of you, it doesn't just hear you - it hears the room around you.
Even if it's a cardioid mic and is listening mostly to just you, it's still picking up reflections from your voice or instrument that are bouncing off the walls and coming back to the mic. The goal of acoustic treatment is to minimize the pickup of such reflections so your primary sound source comes through as pure as possible.
So why not just put some cardboard or foam behind the mic?
Some materials are good at absorbing or reflecting particular frequencies - for example, foam absorbs highs really well, but does nothing for lows.
Unlike cheap foam RF imitations, sE's patented multi-layer technology works evenly across the whole frequency spectrum to ensure a balanced, even sound with no coloration at all.
This is what makes the Reflexion Filter unique, and makes it the choice of the biggest recording artists in the world - whether they're working in untreated rooms, or working in a professionally-designed studio and just need a little more isolation.
