Fyne Audio SuperTrax Super Tweeter

The SuperTrax is Fyne Audio's flagship super tweeter — a time-aligned, omnidirectional design that extends the high-frequency output of any quality loudspeaker system beyond the limits of the main drivers. It sits on top of the speaker, radiates in all directions, and its contribution is heard not as an obvious addition to the sound but as an improvement to the coherence, space, and detail of the whole system. Available in Walnut and Piano Gloss Black, it is priced at £2,999 per pair and represents Fyne Audio's most refined approach to high-frequency extension.

The concept is analogous to a subwoofer, but for high frequencies. A subwoofer does not simply add bass — it improves the phase coherence of the whole system below the main speakers' crossover point, which is audible as better definition and timing across the full frequency range. The SuperTrax works on the same principle at the top end: extending the frequency response beyond the main drivers and improving the phase and harmonic integrity of the audible band in the process. The effect on bass perception — more defined, better timed — is one of the more counterintuitive results of adding a super tweeter, and one of the most consistently reported.

Omnidirectional Time-Aligned Design

A conventional tweeter fires directly forward. The SuperTrax radiates in all directions from its position on top of the main speaker. This omnidirectional dispersion blends the super tweeter's output with both the direct sound from the main speakers and the reflected sound from the room boundaries — walls, ceiling, floor — in a way that a forward-firing unit cannot. The result is a more even distribution of high-frequency energy throughout the listening space, which contributes to the sense of air and space that characterises the SuperTrax's effect on a system.

Time alignment ensures the SuperTrax's output arrives at the listening position in correct phase relationship with the main speakers. Without time alignment, the addition of a super tweeter can introduce phase anomalies that harm imaging and focus rather than improving them. The SuperTrax's design avoids this: the geometry of the unit is calibrated so that its output integrates correctly with the main driver's radiation pattern.

Positioning and Compatibility

The SuperTrax is designed to sit on top of the main speaker. Piano Gloss Black units include adjustable feet as standard; Walnut units have optional adjustable feet available separately. The adjustable feet are designed specifically to accommodate sloping speaker tops, including the F700 Series cabinets. The SuperTrax is compatible with any quality loudspeaker system — it is not limited to Fyne Audio speakers, though it is a natural complement to the F704SP, the Fyne Audio F1-8, and the Fyne Audio F1-8s.

The Walnut finish is designed to match the Fyne Audio Vintage Series aesthetic. The Piano Gloss Black finish matches the SP and F700 Series finish options.

The S-Trax Comparison

Fyne Audio also make the S-Trax — a more compact super tweeter at £1,000 per pair, derived from the SuperTrax and optimised for the F500 Series. The SuperTrax is the flagship: larger, more refined in execution, and designed for systems where the main speakers are already operating at a high level. The S-Trax is the right choice for F500E, F500S, and F500SP Series systems; the SuperTrax is the right choice when the main speakers are from the F700 Series, the F1 Series, or equivalent high-end speakers from other manufacturers.

Who Is It For?

The SuperTrax is for the listener who has a high-quality loudspeaker system — Fyne Audio or otherwise — and wants to understand what it is capable of with extended high-frequency support. It is not an obvious upgrade in the way a new amplifier or source component is: its effect is systemic rather than dramatic, and it works on recordings rather than on individual instruments. Listeners who respond most strongly to low-level detail, soundstage depth, and the sense of being in a recording space rather than listening to a recording are the natural audience.

It is also for the buyer who is already running the F704SP or the Fyne Audio F1-10s and wants to complete the system. At £2,999, it is priced as a serious component — and should be evaluated as one, ideally in the context of your own system at our Norwich showroom.
