Fyne Audio S-Trax Supertweeters

By extending your speakers’ frequency range far beyond what we can hear, S-Trax enhances detail, sharpens imaging, and even deepens the perception of bass.

• Improve your existing system
  The S-Trax works at its optimum with our IsoFlare point source driver, however any loudspeaker will see improvements in sound. Designed with a sleek, understated look, S-Trax complements a wide range of speakers, making it a perfect addition to upgrade any hi-fi system.
• 360 degree experience
  By using our patented time aligned omnidirectional S-Trax, reflected energy in the room has the same harmonic structure as the direct on axis energy. The result? An increased perception of air and space to the sound.
• Magnesium dome
  Instruments create frequencies far beyond what the human ear can consciously detect—sometimes up to 50kHz or more. Featuring a Magnesium dome tweeter, this lightweight yet rigid material allows for a smooth and extended response, introducing controlled break-up only beyond the audible range.

SENSATIONAL SOUND. SENSATIONAL VALUE.

Music isn’t just something you listen to, it’s something you feel. The deepest bass notes, the richness of vocals, the sparkle of high frequencies all come together to create a truly immersive experience. But what if you could unlock even more detail? Distilling everything we have learnt from developing our original audiophile SuperTrax into a compact, value driven version, the S-Trax extends your speakers’ high-frequency range far beyond what’s normally heard, enhancing clarity, realism, and the sense of space and air to your music.

Room filling 360 Degree Sound

Traditional super tweeters tend to focus sound in a narrow beam, which limits how evenly high frequencies spread across the room. S-Trax takes a different approach. Using our innovative, patented omnidirectional design, it radiates high frequencies in all directions, creating a more open, spacious, and immersive soundstage—no matter where you’re sitting.

• No Frequency Beaming
  Forward firing devices will have a very narrow dispersion at these ultrasonic frequencies, which means they will beam like a torch. The 360 degree design of the S-Trax means there will be no beaming but instead an immersive sound stage.
• Even Response At Any Angle
  In a typical room, a high proportion of sound perceived by the human ear is reflection generated by the off axis response of the speaker. Therefore any enhancement with a super tweeter is best served by an omnidirectional device with even response at any angle, placed at the acoustic centre of the main driver.
• Patented Tractrix profile
  Known to maintain a 90 degree angle at each intersection of the expanding wavefront. The plane acoustic wavefront generated by the dome is translated into a spherical wavefront into the room, where it meets the diffuser.
• Ability to time Align
  The addition of a S-Trax, when time aligned to the acoustic centre of the IsoFlare, will reduce the high frequency phase error by moving the low pass roll off point much higher.

Revealing Harmonic Detail

Most people know that adding a subwoofer deepens bass and improves balance. A super tweeter does the same for high frequencies, revealing hidden details and refining instrument tones. S-Trax enhances this by preserving the harmonic accuracy of our IsoFlare driver, improving timbre across the full range – even in non-IsoFlare designs.

With precise IsoFlare time alignment, it ensures reflected sound in the room retains the same harmonic structure as direct sound, by maintaining these subtle details, S-Trax delivers music with greater realism and emotional depth.

A Spectrum Beyond Hearing

Instruments create frequencies far beyond what the human ear can consciously detect—sometimes up to 50kHz or more. While you may not “hear” these frequencies in the traditional sense, they influence how you perceive music, adding depth, realism, and that indescribable emotional connection to every note. S-Trax ensures you don’t just listen to your favourite tracks—you feel them.

Magnesium Dome

At the heart of the S-Trax lies a precision formed Magnesium dome, engineered to push frequency response up to 50kHz. This lightweight yet rigid material allows for a smooth and extended response, introducing controlled break-up only beyond the audible range housed in a value led design.

Grounding Terminal

Includes an extra earth terminal that grounds the driver chassis to prevent radio frequency interference effects from masking fine detail.

HF Adjustment

HF output controls are integrated on top of the cabinet, offering user adjustment of high frequency energy giving you customisation to your preferred sound.
