Fyne Audio SuperTrax Omnidirectional Super Tweeter, 16–60kHz, 360° TPCD, UK Made

The Fyne Audio SuperTrax is a precision omnidirectional super tweeter designed and built in the UK to extend your loudspeaker system's frequency response from 16kHz to 60kHz, several octaves beyond the conventional upper limit of human hearing. Part of Fyne Audio's SuperTrax Series, it is available in a Walnut finish to complement the Vintage Series, and in Piano Gloss Black.

At its core is Fyne Audio's proprietary 25mm Thin Ply Carbon Diaphragm (TPCD) with a neodymium magnet system, paired with a cryogenically treated 3rd-order high-pass crossover set at 16kHz. The result is an extended, linear high-frequency response that conventional aluminium, titanium, or magnesium domes simply cannot match. The SuperTrax works on the same principle as a well-integrated subwoofer: by raising the effective roll-off point far above the audible range, it corrects high-frequency phase error across the entire audio band, preserving harmonic relationships between instruments in a way that is felt even in the midrange and bass. Fyne Audio's patented tractrix radiator disperses energy uniformly through 360 degrees, ensuring the reflected sound in your room shares the same harmonic structure as the direct signal. The SuperTrax has earned the Editor's Choice distinction from The Ear, and Twittering Machines described the effect as music sounding more open, spacious, and free-flowing.

Why Consider the Fyne Audio SuperTrax

The SuperTrax is the right choice for audiophiles who have a quality system in place and want a meaningful step up in resolution and spatial performance. With its 360-degree tractrix radiator, TPCD dome driver, and cryogenically treated crossover, the design addresses a fundamental physical limitation that all loudspeakers share: high-frequency phase error. Correcting this restores the harmonic truth of the music across the entire frequency range, producing a more open, spacious, and tonally accurate soundstage on every source and in every genre.

Ideal for

• Owners of quality speakers seeking improved resolution without replacing them
• Fyne Audio Vintage Series owners wanting a matched super tweeter companion
• Vinyl and hi-res digital listeners wanting full harmonic recovery from recordings
• Audiophiles familiar with subwoofer integration who want the same at the high end
• Listening rooms where omnidirectional dispersion delivers a coherent sound field
• High-power systems up to 400W RMS
