Fyne Audio S-Trax Promises High-End Detail to More

Fyne Audio's new S-Trax super tweeter promises to deliver all the benefits of its acclaimed SuperTrax omnidirectional UHF technology in a more compact, affordable, and universally compatible form, according to the company.

Created for audiophiles seeking to extract the very best sound from their loudspeakers, S-Trax is engineered to broaden the frequency response far beyond the limits of human hearing while ensuring effortless integration with a wide range of systems. 

Centred around an upward-facing 25 mm magnesium dome driven by a powerful neodymium magnet system, the tweeter is perfectly aligned with a patented Tractrix profile diffuser above, radiating HF energy into the room in a uniform 360-degree pattern. Fyne tells us that this better replicates the sound dispersion of real instruments, rather than the narrowly focused HF 'beam' of a forward-facing tweeter.

The design extends the system's frequency response to over 50kHz (-6dB in room), "enhancing the transient response, spaciousness, and textural detailing of the reproduced music without altering the underlying tonal balance of the system."

The upshot is that the phase relationship of instruments within the audio band is delivered with greater accuracy, returning high-frequency harmonic information that would otherwise be lost, thereby improving the timbre of the reproduced music. 

Moreover, we are told that S-Trax also reduces high-frequency phase errors, ensuring a more coherent and transparent sound when carefully positioned to align with the acoustic centre of Fyne Audio's IsoFlare driver or the tweeter on a typical discrete speaker system.

To ensure compatibility with the widest range of loudspeakers, the 79 × 82 × 149mm 1kg S-Trax is designed to sit discreetly on top of virtually any flat-topped loudspeaker. Fyne has engineered a 3rd-order high-pass crossover set at 16 kHz. S-Trax operates purely in the super-high frequency domain, with a ± 4.5dB of fine-tuning gain to complement rather than compete with the speaker's own tweeter.

Built at Fyne's new Glasgow factory, the S-Trax also benefits from Fyne's proprietary in-house CryoLite Deep Cryogenic Treatment, which minimises micro-distortions and preserves signal purity in the internal wiring. Additionally, the unit is fitted with Fyne's anti-RFI grounding terminal to ensure that minute details are not masked by electromagnetic interference from nearby electronics.

Cost savings have apparently been achieved through a simplified enclosure and satin black finish, as well as the use of fewer esoteric components compared to its flagship stablemate. However, we are assured that S-Trax continues to deliver a greater sense of realism, detail, and musical engagement.

Anji Sosna, MD at Fyne Audio, told StereoNET:

S-Trax was conceived to deliver the same sense of openness, air and realism that has earned the SuperTrax such acclaim, but in a form that more enthusiasts can access and apply to their existing systems. Like our flagship SuperTrax model, S-Trax is about making the science of high-frequency fidelity serve the art of music listening.

The S-Trax is available now with an RRP of £999.99 | €1,199.99 | US$1,299.99 - per pair
