F1-12S
Fyne's Ultimate Statement — 12-Inch IsoFlare in the Finest Special Production Cabinet
Description ⌄
12" IsoFlare floorstanding speaker — the ultimate expression of Fyne Audio engineering. The F1-12S is Fyne Audio's largest F1-Series floorstanding speaker, built around a 12-inch IsoFlare point-source driver combining a 300mm multi-fiber bass/midrange cone with a coaxially mounted 75mm titanium dome compression tweeter. The twin-cavity cabinet fires downward through a BassTrax Tractrix diffuser, and the hand-built 750Hz crossover uses premium components with cryogenic treatment. Front-panel HF and presence controls provide ±3dB room adjustment.
Technical background
The F1-12S is the apex of the F1 Series — a 12-inch IsoFlare driver with 96dB sensitivity delivering full-range performance from a two-way design. BassTrax twin-cavity porting extends response to 24Hz. The Special Production cabinet is built to the tightest tolerances in the Fyne range, with individually matched drivers, cryogenic wiring, and premium crossover components.
Design story
The F1-12S represents the ultimate expression of Fyne Audio's founding design philosophy: maximum performance from minimum complexity, using a single coincident driver of the greatest possible size. It is the most expensive and technically demanding speaker Fyne produces, built by the most experienced craftsmen at Lennoxtown.
