Fyne Audio SuperTrax walnut (pack of 2)

The SuperTrax is a super tweeter developed by Fyne Audio, designed to extend an audio system’s frequency response beyond 20 kHz. It can be integrated into various high-fidelity systems and uses a carbon dome paired with a high-frequency crossover that allows fine-tuning of the treble while maintaining coherent soundstaging.

Dome and magnetic system technology

At the heart of SuperTrax is a 25 mm dome made from TPCD (Thin Polymer Carbon Dome), a material that combines lightness and rigidity. This thin-layer composition enables the dome to vibrate with precision and responsiveness—crucial characteristics for reproducing extreme frequencies without distortion. The magnetic system’s motor uses high-performance neodymium, delivering strong drive while keeping dimensions compact.

This type of construction allows SuperTrax to handle very small excursion amplitudes in the ultrasonic range, where phase errors and propagation delays become audible and can degrade the system’s overall tonal accuracy.

Frequency response and signal processing

SuperTrax extends acoustic response from 16 kHz to 60 kHz, significantly pushing beyond the 20 kHz generally considered the upper limit of human hearing. This extension offers several indirect benefits: it reduces the load on the main tweeters by offloading the highest frequencies, and it enhances the overall perception of clarity and openness.

The 3rd-order high-pass filter at 16 kHz benefits from cryogenic treatment of its components. This approach stabilizes dielectric properties and improves signal transparency by reducing atomic micro-movements responsible for subtle sonic degradation. Precise time alignment ensures that the energy reflected by the dome maintains the same harmonic structure as the direct signal, avoiding destructive phase interference.

Compatibility and settings

The nominal impedance of 8 Ohms and sensitivity compatible with speakers up to 98 dB make SuperTrax universally compatible with existing high-fidelity setups. Recommended amplifier power is capped at 400 W RMS, suitable for most quality audio amplifiers.

A ±3 dB level adjustment relative to the nominal setting allows tailored integration based on room acoustics and user preferences, avoiding excess or deficiency in the ultrasonic region.
