Description

If your project studio walls are bare and every take comes back sounding boxy or bathroom-like, the sE Electronics RF-X gives you a straightforward fix without a full acoustic treatment overhaul. Built as the entry-level companion to sE’s RF-PRO, it borrows the same core design philosophy but swaps in lighter materials, making it easier to mount and reposition around your mic without sacrificing durability.

The RF-X works by wrapping your microphone in a curved acoustic barrier that intercepts reflected sound before it reaches the capsule. Instead of a single layer of foam, it stacks four distinct materials: an outer composite shell, a wool fabric layer, an air gap, and an inner high-density ‘crystal’ foam with undulating curves rather than a flat ribbed surface. That air gap is the key detail — it’s what keeps the filter from coloring your source the way simpler, foam-only designs often do.

Practically speaking, this means vocals, voiceover, and instrument recordings captured near untreated walls come out noticeably drier and more focused, closer to what you’d expect from a treated room. It’s a patented approach from sE Electronics, so you’re not relying on generic foam-slab logic to get there.

Four-layer acoustic filter: composite panel, wool fabric, air gap, and crystal foam
Curved, high-density inner foam design (not flat ribbed foam)
Lighter build than the RF-PRO while retaining durability
Reduces room reflections with minimal signal coloration

A practical pickup for anyone recording in a less-than-ideal space and looking for cleaner results without rebuilding the room.
