Synergistic Research Atmosphere/UEF/HFT Room Treatment System

Folks, if you choose the “Amplified” base scene (with the Atmosphere XL4 and the Red ATM it is designed for) and play back a rock recording, you will get precisely the sonic attributes that Denney says you’ll get: Tighter, punchier low end, greater midrange presence (along with tighter image focus), and a treble with increased sparkle and shimmer but without excessive bite. Moreover, if you dial in “Crunchie” from the “advanced settings” sub-menu you will, indeed, get sharper leading-edge transients on guitar, cymbal, snare, and greater impact on bass and kickdrum within a more intimate soundspace, as if you were listening up close in a rock club. If you dial in “Stadium,” you will get the same base-scene virtues within a much more expansive soundspace, as if you were sitting at a greater distance in an arena.

Working independently of and in conjunction with the Atmosphere/ATM system are so-called “UEF”—don’t ask me what this initialism stands for—panels (rectangular frames with black panes coated with a paint that is said to react to sound) and UEF dots (round constrained-layer-like wafers that are also sound sensitive), both of which you white-tac to your walls. (Synergistic supplies instructions on where to locate each of these devices in your room.) If you’re lucky enough to own Synergistics’ superb Galileo UEF wire—which I will review in our upcoming Cable and Interconnect issue—this same technology is built into them, as well. (You can also add Synergistic’s HFTs—tiny thimble-like objects that act like miniature Helmholtz radiators—to your UEF system.) The UEF panels and dots have much the same effect as Holger Stein’s Harmonizers, which is to say they seemingly expand room boundaries, creating a larger, less confused, more neutral and transparent soundfield in which loudspeakers better disappear. When the UEF devices are used with the Atmosphere/ATM system, the disappearing act of both room and speakers is kind of amazing.

Even though parts of the Atmosphere/ATM/UEF/HFT system may sound voodooish, these things work, making smaller rooms sound like larger ones and making big multiway speakers disappear in them like two-way mini-monitors. Moreover, the Atmosphere/ATM devices give you options that no other analog room treatments I’ve played with can offer: the ability to change acoustics to fit both the music and the venue it was played in. Indeed, in conjunction with Synergistic’s UEF/HFT devices, the Atmosphere/ATM system is so predictably, astonishingly, and completely adept at this, it raises an interesting question: Do you really want to “superimpose” a predetermined acoustic and ambient pattern on each and every piece of music you listen to? Isn’t this a little like passively re-engineering your recordings?

Maybe, it is. That said, Synergistic offers “base scene” choices that are fundamentally source-neutral, and I, for one, wouldn’t want to do without the lowering of noise and the subsequent clarity, definition, and boundary expansion that are part and parcel of the Atmosphere/ATM/UEF/HFT experience.

In sum, most highly recommended (even if I can’t explain it)—indeed, so highly recommended the Atmosphere/UEF/HFT system.
