HFT

Tune your acoustics.

About the size of a shirt button, yet powerful enough to transform the way you experience music, HFT’s improve nearly all aspects of system and room performance. With HFT’s your speakers and room disappear leaving you with nothing but a live holographic musical event in your listening room, or living room. HFTs oscillate at high frequencies creating an energy field in your room that overpowers room vibrational distortions to correct phase and frequency interactions for harmonic balance in your treated room. You hear an increase in depth and width, with clearer more extended highs, and tighter bass. Everything sounds more live, clearer, and more natural than you could ever imagine.

The sound of your listening room is made up of hundreds if not thousands of vibrating surfaces – all reacting to the energy your stereo system creates. Each piece of furniture, your walls, your ceiling, equipment racks, glass windows, light fixtures, knick knacks and even your speaker cabinets and the enclosures of your components all vibrate and resonate out of tune with the music. Think of it this way: your room and its furniture are like one big instrument with 500 strings. Every time your speakers create a note these strings are being excited – and that’s the problem, not one of those 500 strings are in tune. The fact is, they are all resonating out of tune – distorting your music. The resonance of your listening room is literally pushing back on your soundstage, compressing the air and decay of notes and distorting fundamental harmonics in your favorite music. This is why most systems have soundstages that primarily exist in and around the speakers. This is also why many systems are set up like a gigantic pair of headphones with extreme speaker toe-in creating one narrow sweet spot that prevents you from sharing the joy of music with others.

So what to do? In the past, the answer was to dampen a room with acoustic absorption until it measured flat while redirecting reflections with diffusers. Unfortunately, neither of these solutions address the real concern which is how to make your listening room conducive to music. Overdamped rooms sound dead with little or no decay while even moderate dampening can stifle the sense of air and decay found in live music. Diffusers render a sound with a little sense of the live hall even when recordings are capable of recreating breathtaking soundscapes. Obviously, venues designed for unamplified acoustic performances would never rely on dampening and diffusion alone. Over-dampen a theater and you won’t hear the subtleties of a solo guitar or the subtle intonation of a piano unless you are sitting near the front row. This is why the best venues are somewhat live with reverberations that complement the performers and their instruments. Where amphitheaters voiced like the average audiophile’s listening room it would have thousands of surfaces resonating out of tune with the music, interspersed with absorption that makes live music sound flat. In fact, the acoustic noise floor in rooms with random resonating items actually increases with volume. It is this variable increasing noise floor that prevents you from ever experiencing the magic of live music in your home.

A new answer. HFTs are tiny high-frequency transducers that clean up high-frequency harmonics in your listening room. You see, harmonics are interconnected, so when you affect harmonics -even those beyond the limits of human hearing – you also affect lower frequency harmonics you can hear. HFTs literally cancel harmonic noise on any surface they are placed. Simply follow our easy placement guidelines, 5 HFTs at a time, to systematically overcome your room’s tendency to fight with the music your system is trying to recreate. HFTs replace random out-of-tune resonance with a sympathetic resonance that complements the music. Just 5 HFTs can affect a meaningful improvement to the average listening room, while additional HFT 5 and 10-pacs improve your listening enjoyment further still until you ultimately bring your entire listening room in sync with the music.

HFT X wide angle Each - $199

Review

"The FEQ and HFTs has brought me closer to the music more than any product I have ever reviewed.  Compared to my previous reference at nearly half the price and considering its size and how it’s applied within our family room (happy wife … happy life), the combination of FEQ and HFTsis my new reference. "

Review

"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. "  - JV

 

 

Review

"The effect on our system was immediately obvious:  A thin layer of hash that had been below my notice (Ain't it always the way?) was removed, clarifying a system that I already thought was exceptional."

Review

"Suddenly, the Synergistic name didn’t sound so far-fetched; there was a synergy across the frequency range that rarely happens in audio"

Manuals

Step 4

Add HFT Wide Angles for width and scale

HFT Wide Angle’s are added sparingly to a room already treated with HFT’s. With a wider and more powerful dispersion pattern, they dramatically increase your sense of immersion in the sound field while expanding the scale and dimension of your soundstage.

Damped rooms - Place HFT X Wide Angle on your front wall, centered between the speakers at about ear level.

Moderately damped rooms - Place HFT Wide Angle on your front wall, centered between the speakers at about ear level.

Lively rooms - Not recommended.  See Level Two guide below for additional placment.

Damped, moderately damped rooms and lively rooms -Place HFT Wide Angle on the left wall, near listening position at about ear level.

 

Damped, moderately damped rooms and lively rooms -Place HFT Wide Angle on the right wall, near listening position at about ear level.

Damped and moderately damped rooms - Place HFT Wide Angle on each side wall behind the main speakers when speakers are pulled a fair about of the way into the listening room -or- on side walls between the listening position and the main speakers.

Lively Rooms - Not recommended

Damped and moderately damped rooms - Place HFT Wide Angle on each side wall behind the main speakers when speakers are pulled a fair about of the way into the listening room -or- on side walls between the listening position and the main speakers.

Lively Rooms - Not recommended

Damped, moderately damped and lively rooms - Place the 3rd HFT wide angle on the rear wall behind the listening position. Test vertical height for balance (higher and lower placement from ear level will provide more warmth).
