sE Electronics RF-PRO-U Reflexion Filter PRO

The original, patented, portable acoustic treatment device: the Reflexion Filter PRO.

Beautiful concert halls, gigantic high-ceilinged spaces, lofty stairwells with glorious natural reverb...capturing the sound of an acoustically-pleasing room can make a great recording truly special. But getting a good sound in a bad space is very, very difficult. What if you're an artist recording at home? What if you don't have the budget for a properly treated studio? What if you move to a new house or apartment? What if you don't want to hear your room?

Since we invented the Reflexion Filter in 2006, over 120,000 units have made their way into studios and homes worldwide - and it remains the indisputable industry standard for portable, effective acoustic treatment.

sE's Patented Multi-layer Technology

When you put a microphone in front of you, it doesn't just hear you - it hears the room around you.

Even if it's a cardioid mic and is listening mostly to just you, it's still picking up reflections from your voice or instrument that are bouncing off the walls and coming back to the mic. The goal of acoustic treatment is to minimize the pickup of such reflections so your primary sound source comes through as pure as possible.

So why not just put some cardboard or foam behind the mic?

Some materials are good at absorbing or reflecting particular frequencies - for example, foam absorbs highs really well, but does nothing for lows. Unlike cheap foam RF imitations, sE's patented multi-layer technology works evenly across the whole frequency spectrum to ensure a balanced, even sound with no coloration at all.

Built By Hand

Each Reflexion Filter Pro is meticulously hand-crafted by our team at the sE factory - not mass-produced by an army of machines - and made to last for years and years of recording.

Flexible, Versatile, Ultra-Stable Hardware

In 2016, we completely redesigned the RF Pro's mounting hardware to increase stability, simplify ease of use, and provide an updated level of performance, durability, and aesthetics. It allows panning and tilting for maximum flexibility, and all moving parts are chromatized to ensure low wear. The extra stability means that your RF Pro can be positioned solidly at any angle to help provide a "dry" sound when recording any source - vocals, acoustic and electric guitars, amplifiers, drums, room mics, strings, and countless other instruments.
