The largest and most effective addition to the classic Reflexion Filter® lineup



The largest and most effective addition to the classic Reflexion Filter® lineup: RF SPACE.

The RF SPACE (Specialized Portable Acoustic Control Environment) marks another step forward for the professional tracking engineer.

With a larger surface area, enhancement of sE’s patented multi-layer technology, deeper air gaps, and more efficient materials, the SPACE offers great full-bandwidth absorption, isolation, and diffusion to help you gain control over your acoustic environment. Larger than our industry-standard RF Pro and entry-level RF-X, the added size also makes the SPACE filter perfectly suited for larger microphones.


Each SPACE filter is hand-built 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.

New specialized mounting hardware allows the SPACE to be easily mounted on any microphone stand or drum hardware, with a full range of motion – adjustable and lockable horizontally, vertically, and tilted at any angle.

This makes the SPACE utterly stable and effective in any recording environment.

The SPACE also utilizes our most advanced patented multi-layer technologies to create a balanced, acoustically neutral environment around your microphone. This means the SPACE doesn’t affect the sound of your favorite microphones, which can happen with imitation “reflection filters” from other brands.

“I have used the SPACE Reflexion Filter several times while in Hollywood recording Blake Shelton’s vocals at his home. The filter doesn’t seem to change the tonality of the vocals at all…it’s the closest thing I have found to having consistency when recording in several environments. It simply levels the acoustic playing field, regardless of where I decide to record.”

– Scott Hendricks, EVP A&R Warner Music Nashville / producer (Blake Shelton, Faith Hill, Trace Adkins, Alan Jackson, Brooks & Dunn) – sE Artist

“For my last five albums I’ve sung my vocals right here in this room, in my home studio…and without this, it would be next to impossible. If you’re making records at home, you’ve got to have an sE Reflexion Filter.”

– Brian McKnight, R&B Singer-Songwriter / Arranger / Producer / Musician (watch video here)

“I’ve used them on vocals and instruments alike where I either need more isolation from other sounds/instruments in the room, or I don’t like the character of the room and I’m trying to minimize the amount of room sound pulled into the mic.”

“You can never have enough tools and tricks to get the job done. This is exactly the kind of tool that, once you have it, you’ll use it over and over.”

– Neal Cappellino, GRAMMY®-winning producer/engineer (Brad Paisley, Vince Gill, Alison Krauss & Union Station) – sE Artist

“Before I got my RF Space I had a bulky portable vocal booth that was an eye sore in my home studio. The RF Space is so much more convenient & works just as well, if not better!”

– Matty Mullins, Singer/Songwriter (Memphis May Fire) – sE Artist

“…the boxiness and pinging from the room disappeared. Across a whole album the room ceased to be an issue; everything sounded as though it had been recorded in a decent vocal booth.”

“It made a $0 an hour bedroom into a professional recording space. The RF Space is an answer to one of the biggest problems in getting a great sound; it will help a microphone work the way it should do, even in the worst of rooms.”

– Simon Franglen, GRAMMY®-winning composer / producer / musician (‘Avatar’, ‘Titanic’, ‘Spectre’) – sE Artist

“I can’t even explain how much of a difference it makes. All the ‘hollowness’ and ‘harsh high end’ and weird wooly sound is gone from all vocal tracks instantly! Sounds like a real booth. I cannot believe it actually works as good as advertised…had a cheaper [other filter] on before, that thing was nothing compared to this. This is the real deal.”

– user ‘kangking’ (full review) (studio website)

“SPACE is a hit; we’re big fans of the RF Pro, and count it as an essential studio tool for providing additional acoustic isolation around vocal and string recordings – but there’s no doubt that SPACE does the job even better. On test recordings, we noticed cleaner results even less influenced by our studio’s natural acoustic reflections, which made mixing them more immediately creative, with fewer ‘corrective’ EQ changes required.”

“A number of imitation ‘reflexion filters’ have come to market since sE’s original but very few actually do what they’re supposed to, which is to improve acoustics around recordings. SPACE absolutely underlines sE’s status as the market leader in this field.”

– Future Music / Music Radar (full review)

“This thing is the bomb. If your room isn’t the greatest, before spending money on the latest la-dee-da microphone you should seriously consider getting one of these. Simple, built well but fairly light weight… it goes a long way toward taking the room out of the equation. My own converted 12’x14’ basement studio with carpet and old wood paneling has a kind of stuffed-head wooly midrange muck in the vocals. This completely fixes it.”

“The Best! I have a project studio and I had a cheaper “Mic Shield” before this. I recently upgraded my studio and bought this filter. I can tell the difference immediately. Sounds like a booth where I record now. It’s not even funny how much better it sounds. Incredible!!!!!!! I’m literally blown away. Went from “Hollow” sounding vocals, to full sounding vocals with almost no extra background noise!!!! This “Space” Reflexion Filter is the best!”

“Outstanding! I would recommend the sE Space to anybody who is looking to get that pro studio sound! It’s 10 times better than the cheap foam reflection filter I used to have. I used to get some high frequency sizzles when I recorded with the foam filter but with the Space there are no sizzles at all, only the ones the mic makes LOL! The sE Space and a good condenser and you’re good to go!”

“This does a great job of focusing the sound. I didn’t know what to expect. I ordered this based on reviews I had read online and some YouTube clips that I saw. I use this with a ribbon mic, and this really helps bring the sounds into focus. It works great on both guitars and vocals. For guitars, I am mixing up some small vintage amps (1946 era).”

on the Reflexion Filter® Series:

“I use it to keep the bad out and the good in. On vocals in certain rooms, on guitar cabs, and even on drums (floor toms and kicks).”

– F. Reid Shippen, GRAMMY®-winning Mixer / Engineer / Producer (India.Arie, Ingrid Michaelson, Jonny Lang) – sE Artist

“Everyone should have one.”

– Ryan Hewitt, Producer/Engineer (Red Hot Chili Peppers, The Avett Brothers) – sE Artist

“I like to do vocals in the control room – much more direct interaction with the vocalist, so it’s perfect for that. With so many of us working in all sorts of situations these days, the Reflexion Filter transforms any of these into a viable recording environment.”

“I also think it’s a wonderful device for students to know and learn about, to hear the difference with and without the filter. All audio schools should have them.”

– Lenise Bent, Producer / Engineer (Blondie, Steely Dan, Supertramp, The Band, Fleetwood Mac)

“The Reflexion Filter makes a huge difference in small recording spaces that are more and more the norm…”

– Andy Bradfield, Producer (David Bowie, David Gray, Rufus Wainwright)

“Trust me, they will change your recording process for the better.”

– Ricky Lawson, Drummer (Michael Jackson, Quincy Jones, Whitney Houston)

“After using this, I instantly realized how many problems I had in my booth, because all of a sudden they weren’t there anymore.”

“As far as clarity is concerned, the filter made the biggest difference.”

“Everybody should get this product if you’re thinking about recording anything. Because it’s going to take you to the next level of professional and quality recordings.”

“Best option on the market other than an actual vocal booth/room.”

“It did two things: one, made capturing my instrument’s true sound much easier, and two, saved me lots of money.”

“I was pretty skeptical when I bought this, but I finally gave in after listening closely to recordings I’ve made in my living room. I would now say that this is a must have for any project studio with an untreated room.”

“You need this even if you don’t think you do. Bottom line: I didn’t know how good my equipment could sound until I got this little fellow.”
