Next stop, the Twilight Zone.

Imagine listening to Charlie Parker at Birdland, then walk into Carnegie Hall and get seated in the best seats in the house. This is possible when you add Atmosphere to your listening room. No other technology allows you to tailor the size and scale of your soundstage, with stunning realism, to accurately portray the music and venue you are experiencing. The Atmosphere is a two-channel, multi-wave RF field generator with the power to transport you to the live event. Simply place Atmosphere it is your room, turn it on, and tune out.

Atmosphere began when our lead designer Ted Denney contemplated why systems seem to sound better late at night and worse mid-day. As a pioneering designer of the first high-performance power cord, the original AC Master Coupler of 1994, and his later work in 2007 to develop the world’s first patented non-current limiting AC filter found in our PowerCell AC line conditioners, he knew there must be more to the mystery of what we hear late at night vs. mid-day than just the state of AC coming out of the wall. After all, if it were only AC than power conditioning and high-performance power cords would have solved this problem long ago.

So we began researching variables that could contribute to the mystery of midnight vs. mid-day system performance and came to the conclusion that man-made and solar RF must play a significant role. This led us to research of factors that contribute to fluctuations in the Earth’s ambient RF environment. Ted reasoned that if differences in RF can degrade the sound, then RF can be modeled and shaped to improve the sound.

The NEW Atmosphere Satellite is an outboard broadcast antenna that connects to Atmosphere Infinity with an included ethernet cable for increased signal strength as well as improved dispersion of Atmosphere’s signal throughout a listening room. This is of particular benefit for larger rooms, rooms that preclude the use of a single Atmosphere placed in the one location where a single Atmosphere is most effective, directly between your two main speakers, and for users seeking maximum effect in small, medium and larger rooms. And when you are daisy-chaining one or more Satellites to a single Atmosphere Infinity, you dramatically upscale performance to realize each of Atmosphere’s different scene settings with greater clarity and character.

Who it’s for: People with difficult rooms that would otherwise compromise Atmosphere’s performance because of less than optimal placement options including rooms that preclude the use of a single Atmosphere between the two main speakers or anyone who wants to experience the ultimate from Atmosphere’s scenes as selected on the iPad control app.

The Synergistic Research FEQ Carbon is a third-generation, two-channel acoustic field generator.  New to the FEQ Carbon is a wholly redesigned PCB with dual RF generators. The first function of the redesign was to provide the ability to create different wave shapes, and the second was the addition of a 2nd, independently controlled ULF generator channel.  This is similar to what has been used in the SR Atmosphere Infinity but is the first FEQ to have this ability, which meant 100’s of hours in the listening room finding the perfect combination of options and settings.  Next was the new carbon fiber chassis.  Not only cosmetically beautiful, but the carbon fibre chassis also improves the broadcast of ULF frequencies through its conductive weave. As a result, layering, three-dimensionality, and holographic realism are much improved over all single frequency FEQ’s of the past decade.  In some aspects, the FEQ Carbon even outperforms the much larger and more complex Synergistic Research Atmosphere Infinity as we have isolated two different frequency combinations that represent a near-perfect yin and yang with focus and clarity on acoustic recordings and a more holographic soundstage on recordings mastered to convey a large and enveloping sound field. 

Who it’s for: Anyone who wants to improve the acoustic response of their listening room without the complexity of iPad control, simply turn it on, set it, and forget it.

Atmosphere Satellite

Atmosphere Infinity Satellite (52 inches tall)
Atmosphere Mini Satellite (14 inches tall)

Atmosphere Infinity and Atmosphere Mini X4 are the first expandable models in the line of Atmosphere Acoustic Field Generators. Using either ethernet port located on the rear of the Atmosphere Infinity or Atmosphere Mini X4 and the included ethernet cable, you can connect multiple Atmosphere towers, drastically increasing the performance of the Atmosphere acoustic system. Both ports on Atmosphere Satellites can be used as a signal in or signal out, allowing users to daisy chain multiple towers. Any Atmosphere Satellites connected to an Atmosphere Infinity or Atmosphere Mini X4 will broadcast an identical signal, allowing you to now control all of you Atmosphere Acoustic Field Generators through the iPad remote app with a single iPad.

*Minumum HFT Level 2 or UEF Panel level 1 must be in place before adding an Atmosphere Device.

Atmosphere Infinity or Atmosphere Mini X4 - Your Atmosphere Infinity or Atmosphere Mini X4 is preferred to be placed behind and centered between your speakers.  If you are unable to use this location, the Atmosphere Infinity or Atmosphere Mini X4 can be positioned to the side, however, we recommend an ATM (Atmosphere Tuning Module) is centered between the speakers to refocus your soundstage.

1st Atmosphere Satellite - Move your Atmosphere Infinity or Atmosphere Mini X4 to the left or right corner of the room behind the speakers and place your 1st Atmosphere Satellite in the opposite corner of the Atmosphere Infinity, behind the speakers. Distance from the walls can be tested for best results. If you have one ATM (Atmosphere Tuning Module), keep the ATM centered between the speakers (experiment with the height of the ATM). If you have two ATM’s, place one on top of your Atmosphere Infinity and one on top of your Atmosphere Satellite.

Alternate 1st Atmosphere Satellite - Keep your Atmosphere Infinity or Atmosphere Mini X4 centered between the speakers and place the Atmosphere Satellite centered behind the listening position.

2nd Atmosphere Satellite - With the Atmosphere Infinity or Atmosphere Mini X4 and 1st Atmosphere Satellite in the corners behind the speakers, place the 2nd Atmosphere Satellite centered, behind the listening position

3rd Atmosphere Satellite - Place one of the Atmosphere towers in each corner of the room. The Atmosphere Infinity and Atmosphere Satellites produce identical signals at equal strengths so the Atmosphere Infinity can go in any corner of the room.

ULF X4 Technology

Atmosphere XL4 and FEQ X4

ULF (Ultra Low Frequency) X4 technology adds four times the broadcast power of the original models.  Incorporating four antennas, X4 models provide a 360-degree signal dispersion pattern, significantly improving the effect of the Atmosphere Infinity, Atmosphere Mini X4, and FEQX4.  In addition to acoustic benefits, it also improves the performance of all SR products with UEF Technology. UEF Tech responds to specific ultra-low frequencies, so your Core UEF, Atmosphere X, and Galileo SX cables perform better, along with your HFT’s and UEF Acoustic Panels. Even Tranquility Base UEF component platforms and Black Box low-frequency resonator arrays perform with noticeably increased levels of performance when excited by the strategic ULF signal generated in a 360-degree wave pattern

The Sun and RF Propagation on Earth

There are three major disturbances on the Sun that affect radio propagation here on Earth. Solar Flares, Coronal Holes, and Sudden Disappearing Filament (SDF). Each disturbance causes both electromagnetic radiation and ejection of material from the Sun that alters RF on Earth. What we looked at was how each of these disturbances affects our RF environment during the day vs. late at night with the intention to mimic late-night conditions to improve sound mid-day.

Learn more

Solar Flares

Solar flares release huge amounts of energy, including sustained, high-energy bursts of radiation from VLF to X-ray frequencies and vast amounts of solar material. Most solar flares occur around the peak of the 11-year solar cycle. The first earthly indication of a huge flare is often a visible brightness near a sunspot group, along with increases in UV and X-ray radiation and VHF radio noise.

The sudden increase in X-ray energy from a large flare can immediately increase RF absorption in the Earth’s lowest ionospheric layers, sometimes causing a phenomenon known as a Sudden Ionospheric Disturbance (SID). An SID affects all HF communication on the sunlit side of the Earth and signals in the 2 to the 30-MHz range may disappear entirely. Even background noise may cease in extreme cases. When you experience a big SID, your first inclination may be to look outside to see if your antenna fell down! SIDs may last up to an hour before ionospheric conditions temporarily return to normal.

Typically, several hours after a flare erupts at the Sun, particles begin to arrive at the Earth in the form of a plasma, a highly ionized gas made up of electrons, protons and neutral particles, traveling at speeds up to 300 miles per second. Really high-energy protons may even disable satellites orbiting high above the atmosphere and seem to have a negative effect on the way our audio systems sound.

Coronal Hole

A second major solar disturbance is a so-called “coronal hole”. Matter ejected through this “hole” becomes part of the solar wind and can affect the Earth’s magnetic field.

Statistically, coronal holes tend to occur most often during the declining phase of the 11-year solar cycle and they can last for a number of solar rotations. This means that a coronal hole can be a “recurring coronal hole,” disrupting communications and degrading the subjective performance of our audio systems for several days.

Sudden Disappearing Filament

The Sudden Disappearing Filament (SDF) is the third major category of solar disturbance that can affect RF propagation on Earth. SDFs take their names from the manner in which they suddenly arch upward from the Sun’s surface, spewing huge amounts of matter as plasma out into space in the solar wind.

When the conditions are right, a flare, coronal hole or an SDF can launch a plasma cloud into the solar wind, resulting in an Ionospheric Storm here on Earth. Unlike a hurricane or a Nor’easter in New England, an ionospheric storm is not something we can see with our eyes or feel on our skin. However, we can see the indirect effects of an ionospheric storm on magnetic instruments located on the Earth’s surface because disturbances in the ionosphere are intimately related to disturbances in the Earth’s magnetic field.

During a geomagnetic storm (“geo” means Earth, in Greek), we may experience extraordinary radio noise and interference, especially at HF. You may hear solar radio emissions as increases of noise at VHF. A geomagnetic storm generally adds noise and weakens or disrupts ionospheric propagation for several days.

Solar Flares, Coronal Holes, The Sudden Disappearing Filament, and Wi-Fi—Oh my.

In a nutshell, we discovered that during the day ambient RF is stronger while the Earth’s Schumann Resonance is weaker in relation to overpowering solar and man-made radio frequencies. Typically speaking the ambient RF environment is at a higher frequency and is more complex during the day, and at a lower frequency and somewhat less complex late at night as our planet turns away from the sun. While charting Solar Flare, Coronal Hole and SDF activity we learned that the prevailing RF environment is affected by solar activity much more during the day, and less at night and this led to the discovery of specific RF environments conducive to what we perceive as good sound.

The RED Atmosphere Tuning Module transforms your system with warmer, more liquid musical tones, when compared to the ATM Carbon, painting a sonic picture that is vivid yet relaxing. Refining the texture of vocals and instruments, and adding a more liquid and resonant bass.


Atmosphere Tuning Module

 An astounding transformation of your system’s musical presentation occurs simply by placing an Atmosphere Tuning Module (ATM) on your Synergistic Research Acoustic Field Generator (FEQ Carbon or Atmosphere) or on your speakers. How can such a small thing cause such a grand improvement? All frequencies are related to and interconnected with each other and positively affected by the oscillating ATM excited by sound waves within your room.  The walls of your room will fall away as you begin to hear spacial queues and low level ambient information start to surround you, while any harshness in your system is augmented into refined delicate musical tones.

The new ATM Carbon was explicitly voiced for the new FEQ Carbon with its breakthrough ULF frequency combinations. Still, it is also a significant improvement over RED and GREEN ATMs when used with Atmosphere Acoustic Field Generators. When you place ATM Carbon atop FEQ Carbon, you create a more natural holographic scale with a lower perceived noise floor for effortless sound where vocals and instruments take on lifelike timbre. In addition, frequency extension improves from bottom to top, where high frequencies seem to decay into a much larger space, and bass notes are better controlled and more impactful. Think of ATM Carbon as a turbo charger for the new FEQ Carbon. Available with a no-risk 30-day money-back guarantee so you can confirm performance before making a final decision.

Black and Chrome

Both the Red and Green ATM are available in a brushed black finish or polished chrome finish to match you Atmosphere Tower.

As good as everything sounds, it only got better with the Atmosphere XL4. Amazingly, what you read in the scene descriptions is exactly what you get. As mentioned, we were very fond of the “Ethereal” + “Air & Grounded” settings. The improvement in resolution, contrast, and control almost sounded like a source upgrade. I wish I were exaggerating.

The HFT/FEQ combination serves to make your listening room canvas more pristine so that when your audio system paints the music on it, the end result is a lot more true to life. Needless to say, the Synergistic Research HFT/FEQ combination I used in this review is not going anywhere. They are now an integral part of my reference audio system.

-Malcolm Gomes - June 2018 - Issue 97


“Need more space and ambiance? More there thereness… then this is final frontier in atmospheric realness-ness…”


“The combination of the Atmosphere and ATM delivers on its promised performance and showed itself as an essential upgrade to my reference system. Now with the Atmosphere and ATM in my system to stay, critical music listening is possible day or night. Highly recommended”


“By now we are ready for Synergistic Research’s ‘WTF’ moment”


“The combination of the FEQ and HFTs has made the biggest improvement in my system’s performance since I been reviewing high end audio components over the last 11 years.”

“Thank goodness I am not a HiFi journalist who has to put into words what Atmosphere Infinity plus Satellite are doing to the sound of my system!? Is “incredible” an adequate term? I do not know.

Thank goodness I am not a HiFi journalist who has to put into words what Atmosphere Infinity plus Satellite are doing to the sound of my system!? Is “incredible” an adequate term? I do not know. But I do know that everybody who has ears and a decent system to listen to should test these “Towers“ and let his ears decide. If he (or she) does not hear a significant improvement concerning the sound quality of his/her system he (or she) should look for a different hobby!!! In my system, they just do magic – nothing more, nothing less!
Due to the “circumstances“, I can also say that the improvement created by the Satellite is beyond my expectations.  I’m fully aware of the fact that everything I say is subjective and as adjectives describing the sound quality of a system may be interpreted differently by different people, I spare me and you any “HiFi journalist prose” but rather try to explain in a hopefully understandable way what the sound does to me whenever I sit in front of my system for concentrated listening.  To give you an idea of what happened in my living room I want to go back a bit:
It is generally acknowledged that Class A Amps need at least an hour or longer to reach their full performance. To my surprise, this “warm-up period” seemed to have gone. However, I quickly learned that it had not gone at all, but the sound of the cold amps now is at least as good as the sound was at operating temperature without the Atmospheres. I think this comparison is one way of showing what the Towers do because I don’t think there is any serious way of expressing a percentage concerning the improvement as nobody knows what 100 percent is.

So what does the music do to me when the system has reached the correct temperature?  Music means highly personal emotions to me and these can manifest themselves in different ways when listening to certain passages: e.g. a comforting shiver is sent down my spine, my feet can’t stop tapping, and – as the headbanging days are over – I gently move my head to the rhythm, or I just close my eyes and the music makes me forget anything around me including my speakers. The sound fills the room and makes me very happy and lets me relax. So I often extend the listening sessions deep into the night.
What it boils down to maybe described like this: If only everything was as easy as installing about 40 HFT’s of all kinds, 3 ATM’s and Atmosphere Infinity plus Satellite to achieve such an improvement concerning the sound quality of one’s system.
Just like the doubting Thomas who only wanted to believe what he could see with his own eyes, I only believe what I can hear with my own ears. Therefore I tend to be skeptical when I read or am told that there is something absolutely new and has never been there before and is better than all the rest etc. etc. …..
In this case, I can only support your description of what the Atmospheres do and advise everybody who is taking this fantastic product into consideration - test it!!! IMHO you won’t be able to listen to your system without these SR tools any longer.

With most musical regards

Atmosphere Scene Gallery App

Pair with a linked ATM.

Atmosphere is a multi-channel signal generator with millions of potential adjustments and when properly calibrated, compliments an infinite variety of music, different systems, and even rooms with known issues— like an abundance of glass or hard reflective surfaces. To control Atmosphere, there’s an included iPad app. Simply pick from the three base scenes—Intimate Acoustic, Hologram, and Grand Canyon to calibrate Atmosphere’s field to the type of music you’re listening to.

The Synergistic Research Atmosphere remote app requires an iPad with Bluetooth BLE capability (iPad 3rd generation and newer or iPad mini and newer)

As the name implies Intimate Acoustic is perfect for small scale recordings of whenever you want a precisely focused sound stage that places the the performance primarily between your main speakers.

Holographic is perfect for performances recorded in a live hall, or mastered with reverb and is more layered front to back than either Intimate Acoustic or Grand Canyon. Holographic allows for the greatest sense of envelopment off the three standard scenes making you feel as if you are sitting in the actual recorded space.  Holographic dimensionally favors soundstage height and layering with a strong sense of acoustic space.

Grand Canyon is perfect for large scale classical and amplified performances or anytime you want a wide soundstage with minimal envelopment. This scene creates a wall-to-wall soundscape that starts behind your speakers with excellent depth, precise image outlines, and focus. Grand Canyon seldom if ever presents envelopment around your listening position but rather places the performance behind your speakers with maximum soundstage width.

Maintain the energy of amplified music with sharp leading edges and powerful dynamics. Ideal for live and studio recordings like Rock n Roll, Pop and modern amplified Jazz. In the default setting low frequencies are tight and punchy, mid-range is immediate with high frequencies that are not overly smooth, or etched.

Advanced Settings: ‘Crunchie’ removes any politeness from hard driving electric guitars, horns and leading edge transients leaving nothing but the raw amplified event. ‘Stadium’ opens up the sound field and is perfect for larger scale venues.

Perfect for Electronica, Orchestral, and New Age recordings. Ethereal presents the maximum scale possible without limitations. On already holographic recordings you hear scale and envelopment that transcend the boundaries of your listening room in a most dramatic way. In its default setting music is gorgeously lush and layered with envelopment that places you in the middle of a live event.

Advanced Settings: ‘Air’ opens up high frequencies and enhances your system’s ability to portray a maximum sense of hall and decay. ‘Stratosphere’ is the ultimate setting for width, depth, layering and air.

Atmosphere is sold with an unconditional money back guarantee. Contact your SR dealer or distributor to audition the world’s most advanced acoustic technology today.

Presents larger acoustic recordings with an accurate sense of scale, natural layering and envelopment. Frequencies sound more linear than Holographic while sound staging is wider and more layered than In My listening Room and amplified music sounds softer than the Amplified scene.

Advanced Settings: ‘Near’ moves you closer to the performance with sharper image foes. ‘Expansive’ opens up the sound stage over the default ‘Layered’ settings with softer image outlines.
