Description
The SuperTrax is Fyne Audio's reference supertweeter: a patented, 360° omnidirectional, time-aligned design that enhances a system by harmonising the room's reflected high-frequency energy with the direct sound. Its transducer utilises a 25 mm Thin Ply Carbon Diaphragm (TPCD) with a neodymium motor and a cryogenically treated third-order high-pass filter at 16 kHz, extending the speaker's response up to 60 kHz, several octaves beyond the typical human hearing range. Just as a subwoofer reinforces bass and improves phase, the SuperTrax applies the same principle in the high-frequency domain, preserving harmonic integrity. It offers a level adjustment of ±3 dB and is available in Walnut —matching the Vintage series— or High Gloss Black, with adjustable feet for levelling on inclined tops such as those of the F700 series.
- Patented 360° omnidirectional supertweeter with time alignment
- 25 mm thin ply carbon diaphragm (TPCD) with neodymium motor
- Response up to 60 kHz with a third-order high-pass filter at 16 kHz, cryogenically treated.
- ±3 dB level adjustment; adjustable feet for angled tops (e.g. the F700 series)
- Finished in Walnut (matching the Vintage series) or High Gloss Black
Technology
When temporally aligned with the acoustic centre of an IsoFlare transducer, the SuperTrax reduces phase error at high frequencies by shifting the low-pass crossover point significantly higher.

Before choosing this model
SuperTrax uses a 25 mm Thin Ply Carbon diaphragm and a third-order high-pass filter at 16 kHz. It has ±3 dB level adjustment and measures 86 × 140 × 257 mm. Check the depth and slope of the intended support surface: the manufacturer specifies different levelling options by version. The stated ultrasonic response does not guarantee an audible improvement in every system.
Enquire with the exact loudspeaker and amplifier models, and confirm the finish variant and any levelling hardware needed. An isolated power figure is not a basis for choosing it.
Price, selected version, availability and estimated lead time are confirmed individually before any order.
Purchasing, listening and delivery
Ordering and system matching
Ask about the selected version and matching with your amplifier, sources and room. Supply arrangements will be confirmed in the quotation. An enquiry does not confirm a sale.
Listening sessions and demonstrations
You can request a listening session by appointment at our Barcelona office (Carrer de Modolell, 57). When we arrange the appointment we confirm which equipment is available to hear, along with the date and time.
Home demonstrations are not offered for this product.
Delivery and setup
Delivery, its cost and the estimated timing are confirmed in writing in your quotation, for your delivery address and before you accept it.
Installation and setup can be requested as an additional service. We assess feasibility and quote it separately.
