New, 15,800 yen The RF-X is a reflection filter designed for artists who want to keep costs down, based on the concept of "making the Reflexion Filter® more accessible." The basic design follows the industry-standard Reflexion Filter PRO. The materials and the structure of the mounting hardware for the microphone stand have been re-examined, and weight reduction has also been achieved. It is specifically designed for vocal recording in home studios, and has a structure that mounts on top of a straight microphone stand. The new materials not only make it lighter, but also maintain durability. The RF-X's filter design consists of a total of four layers: an outer panel made of a composite material with ventilation holes, a wool fabric layer, an air gap layer, and an inner foam layer. This multi-layer structure allows for filtering effects across the entire frequency range, minimizing coloration as much as possible. This is why sE's RF series is chosen.
