How it Works
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 our multi-layered design is to minimize the pickup of such reflections so your primary sound source comes through as pure as possible.

Ultra-Stable Hardware
In 2016, we completely redesigned the RF Pro’s mounting hardware to increase stability, simplify ease of use, and provide an updated level of performance, durability, and aesthetics. The mounting system allows panning and tilting for maximum flexibility, and all moving parts are chromatized to ensure low wear. The extra stability means that your RF Pro can be positioned solidly at any angle to help provide a “dry” sound when recording any source – vocals, acoustic and electric guitars, amplifiers, drums, room mics, strings, and countless other instruments.
Patented Multi-Layer Technology
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.
