sE Electronics RF-X WB Portable Isolation Filter (White)

Portable Microphone Isolation Filter for Clearer Vocal Recordings

The sE Electronics RF-X WB is a compact portable isolation filter designed to reduce room reflections and unwanted ambient noise when recording vocals or instruments. Built using the same acoustic design principles as the Reflexion Filter PRO, the RF-X delivers controlled, focused sound capture for home studios, mobile recording setups, and content creators who want cleaner recordings without permanent acoustic treatment.

Four-Layer Acoustic Filter Design That Reduces Room Coloration

This isolation filter features a proven four-layer acoustic construction that absorbs and diffuses sound reflections before they reach the microphone. The multi-layer design helps minimize coloration caused by untreated walls, desks, and nearby surfaces. This results in more natural-sounding recordings with improved clarity and consistency, especially in small or acoustically challenging rooms.

Compact and Lightweight for Home and Mobile Studios

With a lightweight vented body and compact footprint, the RF-X WB is easy to transport and quick to set up. It mounts directly to standard microphone stands, making it ideal for bedroom studios, apartments, rehearsal spaces, podcast setups, and on-the-go recording environments. Its portable design allows creators to achieve reliable results in a wide range of locations.

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 larger isolation filters. The rigid outer shell combined with high-density acoustic foam provides durability while maintaining effective sound absorption. This build quality ensures consistent performance for frequent recording sessions and repeated setup and breakdown.

Redesigned Clamp System for Secure and Flexible Positioning

The RF-X WB includes an efficient, redesigned clamp assembly that attaches securely to most microphone stands. The clamp allows easy adjustment of position behind the microphone while keeping the filter stable during recording. This flexibility makes it simple to fine-tune placement for different microphones, vocalists, or recording styles.

Clean White Finish for Modern Studio Setups

Finished in a white outer shell with black acoustic foam, the RF-X WB offers a clean, modern look that fits well in professional studios, home setups, and on-camera recording environments. Its balance of performance, portability, and ease of use makes it a practical solution for improving recording quality without complex installation.
