Fyne Audio has introduced the F1-10 Anniversary, a limited-production flagship loudspeaker created to mark the company’s tenth anniversary. Based on the original F1-10, the new model introduces a newly developed aluminosilicate glass-dome IsoFlare driver and, for the first time in a Fyne Audio loudspeaker, a fully integrated SuperTrax super tweeter.
The F1-10 Anniversary is hand-built at Fyne Audio’s headquarters in Glasgow, Scotland, with each pair individually numbered. UK pricing is set at £37,000 per pair. Fyne Audio describes production as strictly limited, while HiFi PiG reports that only 30 pairs will be made worldwide.
A New Glass-Dome IsoFlare Driver
The most significant change is the newly developed 250mm IsoFlare point-source driver.
The basic architecture remains familiar, combining a multi-fibre bass/mid cone with a centrally mounted compression driver, but the high-frequency diaphragm material has changed completely. The new compression driver uses a 75mm ultra-thin aluminosilicate glass dome.
Glass is an unusual material for a loudspeaker diaphragm, but Fyne Audio says chemical ion treatment allows the dome to combine low mass with high stiffness while also reducing resonant behaviour compared with conventional metallic diaphragms.
According to the company, the new glass dome provides up to seven times greater resonance damping than a typical metal dome. Its relatively large 75mm diameter also allows it to operate down to a crossover point of 750Hz, preserving the single acoustic centre that defines the IsoFlare concept.
That low crossover frequency means the glass diaphragm is responsible for far more than just the upper treble. It covers a significant part of the vocal and instrumental range, making it one of the key elements shaping the overall character of the F1-10 Anniversary.
SuperTrax Moves Inside the Loudspeaker
Above the IsoFlare driver sits another major addition.
The F1-10 Anniversary is the first Fyne Audio loudspeaker to integrate its SuperTrax super tweeter directly into the cabinet.
The SuperTrax uses a 25mm Thin Ply Carbon Diaphragm (TPCD) and a neodymium motor system. It fires upward into a Tractrix-profile diffuser, distributing high-frequency energy through 360 degrees. Its operating range extends from 16kHz to 60kHz.
Fyne Audio says the purpose is not simply to reproduce frequencies above the conventional audible range. The system is also intended to improve harmonic structure, phase behaviour and the perception of spatial information in the listening room.
A dedicated rear-panel control allows the SuperTrax output to be adjusted by ±3dB. The IsoFlare section also provides separate ±3dB controls for High Frequency Energy and Presence, giving users room to tailor the response to different acoustic environments and system voicings.
BassTrax and Cryogenically Treated Crossover Components
Low-frequency loading is handled by Fyne Audio’s familiar BassTrax Tractrix diffuser system.
A downward-firing reflex port directs energy onto the diffuser, which then disperses bass through 360 degrees. The company says this approach helps reduce the directional behaviour associated with conventional front- or rear-firing ports and makes low-frequency performance less sensitive to speaker and listener position.
The crossover network has also been reworked for the Anniversary model. It uses deep-cryogenically treated components, including ClarityCap PUR polypropylene capacitors, while internal wiring is supplied by Neotech PC-OCC and the speaker terminals are gold-plated WBT Nextgen types.
Crossover frequencies are set at 750Hz for the IsoFlare driver and 16kHz for the SuperTrax system.
From 26Hz to 60kHz
The F1-10 Anniversary is specified as a three-way floorstanding loudspeaker with a room response of 26Hz to 60kHz (-6dB).
Sensitivity is rated at 94dB for 2.83V/1m, with a nominal impedance of 8 ohms. Recommended amplifier power is 20 to 280 watts.
Continuous power handling is rated at 140 watts, rising to 560 watts peak.
The cabinet is built using birch plywood with extensive solid-wood bracing. Externally, the speaker combines high-gloss Burr Walnut and Walnut Veneer, finished with champagne-gold detailing exclusive to the Anniversary model.
Each enclosure measures 1247 × 405 × 585mm and weighs 58.7kg.
Ten Years After the Original F1-10
The original F1-10 was one of the products that established Fyne Audio’s identity after the company was founded. Development began in 2016, and the design helped define the brand’s use of IsoFlare point-source drivers, BassTrax loading and its broader approach to high-end loudspeaker engineering.
A decade later, the F1-10 Anniversary retains the visual and conceptual foundation of the original while introducing technologies that represent a more substantial change than a cosmetic commemorative edition.
The new aluminosilicate glass compression diaphragm and fully integrated SuperTrax system are particularly notable, as they may also indicate where Fyne Audio intends to take its upper-tier loudspeaker designs in the future.
Each speaker is hand-assembled, tuned and finished in Scotland, with individual serial numbering, an Anniversary book, a signed inspection certificate and dedicated accessories included.
The Fyne Audio F1-10 Anniversary is priced at £37,000 per pair in the UK. Production is officially described as strictly limited, with HiFi PiG reporting a worldwide run of 30 pairs.
