Most people know that adding a subwoofer deepens bass and improves balance. The Fyne Audio S-Trax does the same for high frequencies, revealing hidden details and refining instrument tones.
Featuring distilled technology from our flagship SuperTrax, this compact, value-focused super tweeter blends reflected and direct sound through a time-aligned, omnidirectional design, adding air, openness, and realism to your music.
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. S-Trax ensures you don’t just listen to your favourite tracks—you feel them.
Versatile by design, it works acoustically and aesthetically with almost any speaker, but it is the perfect addition for our F500E, F500S, and F500SP Series featuring our IsoFlare driver technology. Available in black.

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.
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.
