sE Electronics RF SPACE Large Multi-Layer Reflexion Filter (Silver)

sE Electronics RF SPACE: The Largest Reflexion Filter for the Deepest Portable Isolation

The sE Electronics RF SPACE is the largest portable reflexion filter in the sE line, a microphone isolation shield built from ten layers of patented Multi-Layer Air-Gap technology reinforced by seven vertical bass-trap pillars. Its oversized 15.75 x 13 x 7.75-inch panel wraps a greater surface area around the microphone than any other RF filter, capturing reflections a smaller shield would miss. Where standard filters tame mostly mids and highs, the RF SPACE is engineered to reach down into the low frequencies that make untreated rooms sound boxy and congested. For the serious vocalist or engineer who wants the deepest isolation a portable shield can deliver, it is the flagship of the reflexion filter family.

Ten-Layer Multi-Layer Air-Gap Technology

The RF SPACE builds on sE's patented reflexion filter design with a full ten-layer stack of alternating absorbers, diffusors and isolating air gaps. The layer sequence runs from a punched aluminum diffusor through acoustic-grade wool, tensioned aluminum-foil membrane diffusors, a polycarbonate diffusor and patented polyester acoustic fiberboard, each separated by an air gap. Those air gaps are the acoustic key: separating layers lets each one act on a different band and lets sound energy dissipate in the space between rather than reflecting straight back to the capsule. The practical payoff is a shield that removes more of the room across a wider frequency range than a simpler single-material panel ever could.

Seven Vertical Bass-Trap Pillars for Low-End Control

The RF SPACE's signature upgrade is a row of seven vertical bass-trap pillars that deepen the internal air gaps and randomize diffusion behind the panel. Low frequencies are the hardest reflections to control because their long wavelengths pass straight through thin absorbers, which is why most portable shields leave a muddy low-mid buildup. The pillars extend the effective depth of the trap and scatter low-frequency energy so it is broken up instead of returning to the microphone. For sources with heavy low end, this is the difference between a controlled, articulate low register and a boomy recording that fights the mix.

Improved Low-Frequency Isolation Over Smaller Filters

Thanks to its size and bass pillars, the RF SPACE delivers audibly better low-frequency isolation than the smaller RF PRO or RF-X. Its larger surface area subtends a wider angle around the capsule, so off-axis reflections coming from the sides and below are intercepted rather than sneaking past the edges of a compact shield. This matters most on deep-voiced narrators, baritone singers, cellos and large instruments whose fundamentals live in the range portable filters usually struggle with. Engineers who found a smaller shield left the low end uneven turn to the RF SPACE for a cleaner, more even result across the whole spectrum.

Heavy-Duty Clamp Locks at Any Angle

The RF SPACE mounts on a robust clamp that is fully adjustable and lockable both vertically and horizontally and tilts to any angle for instrument work. A larger, heavier panel demands a more substantial mount, and this clamp is built to hold the extra mass square and steady behind the microphone. Precise, repeatable positioning is essential because the shield only performs when it sits close and correctly aimed around the capsule. Engineers can lock it upright for a standing vocalist, then tilt it down over a seated cellist or an amp without any loss of stability.

Greatest Surface Area for Maximum Isolation

At 15.75 x 13 x 7.75 inches, the RF SPACE presents the greatest surface area of any sE reflexion filter, and surface area is what determines how much of the room a shield can block. The larger the panel, the wider the cone of reflections it intercepts before they reach the microphone, which is why the RF SPACE isolates more completely than compact alternatives. This makes it the right choice for larger sound sources and for rooms whose reflections are especially problematic. In a truly untreated space, its extra coverage is often what finally makes a recording usable without extensive post-production repair.

Professional Vocal and Instrument Recording in Any Room

The RF SPACE is aimed squarely at professional vocal tracking and demanding instrument sessions in rooms that were never designed for recording. Because it treats sound acoustically at the source, it improves the signal before it is ever converted, adding no noise, coloration or latency the way a corrective plug-in would. It suits voice-over booths, project studios and touring rigs where building permanent treatment is impossible but professional results are still expected. Wherever it goes, it brings a consistent, controlled acoustic environment that travels with the microphone.

The Flagship Choice for Serious Isolation

As the biggest and most capable shield in the range, the RF SPACE is the flagship for buyers who want the deepest portable isolation sE makes. It fits the serious home recordist upgrading from a foam shield that left the low end muddy, the professional who needs maximum control on location, and the studio comparing shields for their most demanding sources. Its size and weight mean it should be paired with a very sturdy, weighted stand, a small trade-off for its class-leading performance. For anyone who has decided that good enough is not enough, the RF SPACE is the definitive reflexion filter.
