Next stop, the Twilight Zone.
Imagine listening to Charlie Parker at Birdland, then walk into Carnegie Hall and getting 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 portray the music and venue you are experiencing accurately.

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.

Two frequency bias, one perfect sound.

Red Frequency: voiced for acoustic instruments, vocals, and smaller-scale performances.

Purple Frequency: convincingly portrays large-scale performances and electronic music.

To use, plug the FEQ Carbon and its internal Ground-Plane into two separate wall sockets in your listening room and place behind and between your two main speakers or wherever you find space. Then turn it on for an immediate and unmistakable improvement in sound. One FEQ Carbon will improve an average size listening room with a greater sense of clarity, a lower noise floor, and more natural harmonics.

Dimensions is 14" tall (Base 4.1" wide x 4.1" deep), MSRP is $1695 ($1895.00 the 230V version). ATM (Atmosphere Tuning Module) sold separately.

"...improvements to sound quality were immediately apparent. The whole sonic presentation took on a liquid quality that was stunning to hear while imaging expanded and low level details emerged from out of nowhere to bring more life to the music. Very impressive units that are now a permanent part of my system..." 
Reviews and Award for the first generation FEQ:



Michael Fremer, Stereophile, Feb. 2015:
"...after listening, I pulled the FEQ’s plug and listened again. Damned if the stage didn’t narrow somewhat, and lose a bit of the vivacious depth and retrieval of ambiance I’d heard with the FEQ plugged in. It just sounded more spacious, and especially more transparent, with the FEQ plugged in. So I plugged it in again..."


Michael Girardi, The StereoTimes, Dec. 2014:"...the largest component in one’s system is the listening room yet it the one component that is commonly overlooked and misunderstood. The HFTs are tiny high frequency transducers that clean up high frequency harmonics in your listening room by cancelling the harmonic noise generated by room resonances. The FEQ is an ultra low frequency RF pulse generator that acts as a low frequency dither to overpower the ambient RFI and EMI fields. 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. Considering the physical size of the HFTs and FEQ as compared to all other room acoustic enhancement devices and their comparative performance, the FEQ and HFT resides in the best in class category for room acoustic treatment. From an ergonomic and aesthetic standpoint alone they are revolutionary in the application of room acoustic enhancement. Happy was the day I removed my previous reference room acoustic treatments and replaced them with the FEQ and HFT’s (and it wasn’t a secret that my family felt the same way). The combination of the FEQ and HFT is a paradigm shift in room treatment device design and delivers on its promised performance..."


Steve Plaskin, Stereophile’s, Oct. 2013:
"...I have never heard anything that was as effective in elevating the performance of a high end system as the combination of the Synergistic Research HFT and the FEQ... soundstage, noise floor, bass detail and dynamic power, midrange and high end clarity all improve with the use of these products... the Synergistic Research High Frequency Transducer and Frequency Equalizer will become a permanent part of my audio system. Removing these components is simply unthinkable given the quality of the sonic enhancement achieved with their use..." Check out the entire review

Customer Feedback:

"...I had no idea how imbalanced my listening room was until I plugged this bad boy in! Words cannot describe how linear my system now is. Bass definition is unreal, instrument separation is very life live, and voices are scary real, with amazing focus and sound staging! Very very happy with these and the HFTS!!!"

" FEQ and 3 packs of HFTs completely transformed my room creating the listening experience I’ve been looking for a very long time. While a lot of upgrading of components and wire over the years improved the quality of sound, the HFTs and FEQ have created a realistic 3 dimensional soundstage, with more inner detailed revealed and a profound overall improvement in listening enjoyment..."

"...picked up 3 HFT 5 pacs (15 HFTs) and an FEQ at Rocky Mountain and just wanted to let you know how wonderful my system now sounds... there’s a Betsy Larkin track playing and it’s as if she’s singing in my living room. The clarity now rivals my headphone rig, no shit. Anyway an amazing product that has whetted my appetite for more..."

"...they [FEQ & HFT] really souped up my system dramatically there was no accessory that I bought ever made this level of improvement..."
