Portable Vocal Isolation Filter for Cleaner Recordings Anywhere
The sE Electronics RF-X RB is a compact, portable isolation filter designed to reduce unwanted room reflections and ambient noise when recording vocals or instruments. Built using the same core acoustic design principles as the Reflexion Filter PRO, the RF-X provides effective sound control for home studios, mobile recording rigs, and budget-conscious creators who want clearer, more focused recordings without treating an entire room.

Four-Layer Acoustic Design That Reduces Room Coloration
The RF-X uses a proven four-layer acoustic filter structure to absorb and diffuse reflections before they reach the microphone capsule. This multi-layer construction helps minimize sound coloration caused by untreated walls, desks, or nearby surfaces. The result is a tighter, more controlled recording that captures the source more accurately, making it easier to achieve professional-sounding vocals in less-than-ideal spaces.

Designed for Home Studios and Mobile Recording Setups
With its lightweight, vented body and compact footprint, the RF-X is well suited for creators working in bedrooms, apartments, rehearsal spaces, or temporary recording locations. It mounts easily to standard microphone stands and can be positioned quickly without complex hardware. This makes it a practical choice for podcasters, voice-over artists, singers, and musicians who need consistent results in changing environments.

Hand-Assembled Construction with Proven sE Engineering
Each RF-X is hand-assembled in sE Electronics’ factory using the same attention to detail found in their higher-end isolation filters. The rigid outer shell combined with high-density acoustic foam provides durability while maintaining effective absorption. This build quality ensures reliable performance over time, even with frequent setup and breakdown.

Efficient Clamp Assembly for Fast and Secure Mounting
The redesigned clamp system allows the RF-X to attach securely to most microphone stands while remaining easy to adjust. Its efficient mounting design keeps the filter stable during recording sessions while allowing precise placement behind the microphone. This flexibility helps users dial in the best position for different microphones and vocalists.

Striking Red Finish with Practical Studio Appeal
Finished in a bold red shell with black acoustic foam, the RF-X RB adds visual character to any recording setup without sacrificing functionality. Its combination of performance, portability, and ease of use makes it a strong option for creators who want improved sound quality without the cost or complexity of permanent acoustic treatment.
