sE Electronics Reflexion Filter Pro Review

A portable reflection filter designed for home studios, the sE Electronics RF PRO Reflexion Filter mitigates the acoustic conditions prevalent in these areas. It has traditionally been expensive to install acoustical treatments on various surfaces due to the extensive testing and construction needed.

As project studios and small satellite studios have become more prevalent, innovative techniques have emerged to address the economics and practicality of dealing with these acoustic problems.

By providing a curved baffle with a patented multilayer design, Reflexion Filter PRO offers an effective solution to this problem. The filter can be mounted using a stand/clamp assembly that can be adjusted to the desired position behind any microphone. Additionally, less of the original source’s acoustic energy is reflected back to the microphone as unwanted room ambiance as a result of this reduction of acoustic energy hitting untreated walls.

The Reflexion Filter was invented by SE Electronics in 2006 and has been used in over 120,000 studios and homes worldwide. It remains an industry standard for portable acoustic treatment.

Putting a microphone near you not only allows you to hear yourself but also allows you to hear the entire area around you. Even a cardioid microphone will pick up some reflections from your voice or instrument that bounce off walls and return to the microphone. By treating the space acoustically, you will minimize the pickup of such reflections, ensuring that your primary sound source is heard as clearly as possible.

Materials have a tendency to absorb or reflect specific frequencies; for example, foam absorbs high frequencies very well, but does not do anything for low frequencies. The multi-layer technology developed by SE provides a balanced, even sound with no coloration across the entire frequency spectrum.

A complete re-design of the mounting hardware for the RF Pro was conducted by sE Electronics in 2016. This was done in order to increase stability and simplify the use of the product, as well as to provide increased performance, durability, and aesthetics.

RF Pro Appearance

In order to maximize flexibility, it offers panning and tilting capabilities, and all moving parts have been chromatized to ensure minimal wear. RF Pro’s extra stability allows you to position it in any position to ensure a dry sound when recording any source, including vocals, acoustic and electric guitars, amplifiers, drums, room microphones, strings, and countless other instruments.

There are six layers in the Reflexion Filter. First, a layer of punched aluminum diffuses sound waves through a layer of wool that absorbs them. The sound waves then pass through a layer of aluminum foil, which dissipates energy and breaks up the lower-frequency waveforms, before they enter an air space maintained by rods that pass through the various layers. Air gaps serve as acoustic barriers.

Following this, the sound waves travel through a layer of wool and then through an outer wall of punched aluminum, which serves to further absorb and diffuse the remaining acoustic energy.

As the sound waves pass to the main filter, 4 formed pieces of state-of-the-art specialist acoustic absorptive material are attached to the face of the main absorber via the extended separation rods. This further serves to absorb and diffuse the sound waves as they pass through.

RF Pro Design

Thanks to its clamping mechanism, the RF PRO can be securely attached to virtually any microphone stand. Despite its six different layers, the Reflexion Filter by sE Electronics makes your microphone sound better because it diffuses sound waves around the microphone. The best part of this portable acoustic treatment is that it mounts to any microphone stand – you can take it to other rooms or to other locations.

An effective way of taming room reflections is to use the Reflexion Filter, which is a fraction of the cost of a full-room treatment. You will want this microphone on your favorite recording device if you record.
