Description

The S-Trax is a compact supertweeter from Fyne Audio, distilling the technology of their reference SuperTrax supertweeter into a more accessible version. It features a 25 mm magnesium dome with a neodymium magnetic system, a third-order high-pass filter at 16 kHz, and Cryo-Lite treatment, extending the system's response up to 50 kHz, beyond the audible range. Its omnidirectional design with time alignment ensures that reflected energy in the room maintains the same harmonic structure as the on-axis direct energy, providing a greater sense of air and space. A control on the top allows adjustment of high-frequency energy by ±4.5 dB relative to the nominal setting. It is compatible with virtually any loudspeaker, though it performs optimally with Fyne Audio's IsoFlare point source drivers.

  • 25 mm magnesium dome supertweeter with neodymium magnetic system
  • Frequency response from 16 kHz to 50 kHz (-6 dB typical in-room)
  • Omnidirectional design with time alignment for an enhanced sense of air and space
  • 3rd order high-pass filter at 16 kHz with Cryo-Lite treatment and energy adjustment of ±4.5 dB
  • Technology distilled from the reference SuperTrax supertweeter; ideal for IsoFlare loudspeakers.

Application

Designed to extend the high-frequency response of an existing system: it operates optimally with the IsoFlare transducer and is an ideal addition to the F500E, F500S, and F500SP series, although most loudspeakers can benefit. It is positioned on top of the speaker, set back from the front of the enclosure according to the official positioning guide.

Technology

It encapsulates the expertise gained with the reference SuperTrax supertweeter into a compact and accessible format; it shares its fixed 3rd order high-pass filter at 16 kHz and the omnidirectional time-aligned design, in a smaller form with a 25 mm magnesium dome.

Before choosing this model

S-Trax is an add-on supertweeter rather than a pair of loudspeakers to use on its own. It has a 25 mm magnesium dome, a third-order high-pass filter at 16 kHz and ±4.5 dB level adjustment. Its 79 × 82 × 149 mm body needs a suitable support surface on the main loudspeaker; physical fit alone does not establish correct integration.

Provide the model of your main loudspeakers and amplifier so the connection, position and level setting can be confirmed. It does not replace a full-range loudspeaker.
