HFT Speaker Kit Mk II dramatically improves your speakers ability to disappear and enable a sonic presentation that is tonally accurate, with the spatial realism and emotional immediacy the music was meant to convey in a way that goes beyond what we believed possible. With six types of precisely tuned HFT (up from three) featuring faster activation and tighter phase alignment, the breakthrough lies in a new controlled asymmetric deployment where each of the seven positions is independently tuned to complement the others in ways symmetric placement never could achieve. The result transcends what seemed possible: instruments bloom with greater body and truth, vocals hang with stunning presence, and recordings scale effortlessly from intimate ensembles to large orchestras—delivering not just better sound, but sound that feels completely right. The HFT Speaker Kit MkII isn’t an upgrade—it’s a complete revolution that reconstructs your soundstage’s phase structure from the ground up.

What Are HFTs, Anyway?

Most people don’t realize it, but your room isn’t neutral. Everything in it—walls, furniture, windows—reacts to sound. And not in harmony. These objects ring back at the music out of time, out of tune, and out of phase. That’s what collapses your soundstage—not your gear.

Our High Frequency Transducers (HFTs) act as miniature acoustic processors to eliminate room distortion by generating real-time phase-locked energy that steps down through harmonic coupling into the range you can actually hear, restoring your music’s natural timing, spatial cues, and tonal clarity. About the size of a shirt button, HFT’s properly placed around the room and speakers are powerful enough to transform your listening room’s acoustics. They’re excited by the music itself—by sound pressure, electromagnetic energy, and RF—and they respond in real time, emitting phase-locked ultrasonic energy tuned to reinforce the music, not fight it. And by the time your walls and knickknacks start ringing out of tune, your brain is already two steps ahead—processing the next wave of sound, guided by HFTs that are locked in with the music and tuned to the phase structure of the soundstage itself.

How HFTs Work

HFTs aren’t passive—they’re excited by the same acoustic pressure, electromagnetic fields, and RF energy your system creates. But unlike the objects in your room that ring late, out of tune, and out of phase, HFTs are engineered to respond instantly and in alignment with the signal’s harmonic structure. That’s how they lock in—not by being programmed, but by being placed where they can synchronize with real energy in real time.

They’re analog. They don’t guess, they react—faster and more accurately than the room itself.

Why Conventional Treatments Fall Short

Now here’s the key: your room is also activated by the music. The walls, the furniture, the glass—all of it reacts to the same energy. But the room reacts slowly. Its resonances are chaotic, delayed, and unmusical. Unfortunately, traditional acoustic solutions—dampening rooms flat and adding diffusers—often fall short of the intended outcome. Overdamped rooms sound dead with no decay, while diffusers eliminate the live hall sense that great recordings capture. Concert venues never rely on dampening alone because it kills musical subtleties. The best venues stay somewhat live with complementary reverberations. If amphitheaters sounded like typical audiophile rooms—thousands of surfaces resonating out of tune mixed with deadening absorption—live music would be ruined. Random resonating objects actually increase noise as volume rises, creating a variable noise floor that prevents you from experiencing live music’s magic at home.

When you place HFTs strategically—on the back wall, above the listening position, and across a tuned grid—you create a fast, phase-accurate feedback loop that overrides the room’s slower, confused responses. You’re not canceling the room. You’re outrunning it. And your brain follows the faster, cleaner signal every time.

Think of each HFT like a harmonic relay. Where you place it determines which part of the soundstage it locks onto—because it responds locally to what’s happening in that section of the room. The result is a reinforcement network that mirrors the timing and structure of the music itself. You don’t hear the HFTs. You hear what they let through—the space, the depth, the life that was buried under your room’s distortion until now.
