Impressive Frequency Range: You'll get bass as low as 28Hz and a high frequency response going over 26kHz, thanks to its 75mm titanium dome compression tweeter.
High Sensitivity: With a sensitivity of 94dB/W, the F1-10 promises an exceptional dynamic range. This makes it compatible with a vast range of amplifiers, from single-ended triode valve models to robust solid-state designs.
Adaptable Performance: The twin cavity BassTrax porting and adjustable controls for HF energy and presence mean that this speaker can adapt to deliver optimum performance, no matter the room size or placement.
Exquisite Finish: The traditional lacquered burr walnut finish with a plinth top ensures that this speaker doesn't just sound good – it looks the part too.
In essence, the F1-10 is not just a speaker; it's a bold statement in audiophile loudspeaker design, combining functionality with elegance.
ISOFLARE™ POINT SOURCE DRIVER: Fyne Audio’s IsoFlare™ driver is a point source system whereby the bass / midrange driver shares a common centre with the high frequency unit. Providing outstanding stereo imaging even off axis, energy is radiated isotropically with constant directivity following the flare of the driver cone. Sound is produced emanating from a single point.
To fully optimise the driver performance, every aspect of this meticulous design has been considered. Eliminating unwanted vibrations which would be detrimental to the sound quality, our IsoFlare™ point source drivers are built around a custom tooled rigid cast aluminium chassis. A vented rear chamber in the substantial Neodymium HF magnet places low frequency resonance well below the crossover region. Pushing the break up mode well above the level of human hearing, the highly rigid 75mm titanium alloy high frequency diaphragm delivers a smooth and extended response, while a copper shorting ring provides low distortion. The unique geometry of the high frequency unit’s waveguide provides a flat frequency response and avoids internal reflections. The HF diaphragm provides a natural and unstressed performance, terminated by a Mylar surround to optimally terminate energy. Such a large diaphragm allows a very low crossover frequency of 750Hz to the bass / midrange cone, ensuring much of the vocal range is handled by the tweeter.
CROSSOVER: Although simple in topology, the design is computer optimised, fine tuned subjectively by critical auditioning. The crossover makes use of high quality precision components, including low loss LF laminated iron core inductors, non-inductive thick film resistors and Claritycap’s high grade MR type HF polypropylene capacitors. High quality gold plated WBT Nextgen™ bi-wire terminals are used, together with Neotech™ PC-OCC internal wiring with virtually no crystal imperfections for transparent signal transfer. The components are hard wired on fibre board panels to minimise vibration, using a special mastic. A specially designed autotransformer using the highest grade silicon steel laminations impedance matches the HF compression driver to the amplifier, with varnish vacuum impregnation to eliminate distortion caused by winding vibration. Cryogenic treatment of the complete crossover relaxes stresses in materials and solder joints to maximise signal transparency. A grounding terminal is fitted to minimise the effect of radio frequency interference masking fine detail.
BASSTRAX™ TRACTRIX DIFFUSER SYSTEM: The F1 Series employs a downwards firing port arrangement using a twin cavity reflex loading system. This loading system broadens the tuning frequency to reduce cone excursion, and acts as a muffler, blocking standing waves produced by the main internal port.
Below the vent in the base of the loudspeaker, the BassTrax™ Tractrix profile diffuser (patent applied for) is used to convert the plain wave energy to an expanding spherical 360-degree wavefront, dispersing energy uniformly into the room. This Tractrix profile has been previously applied to horn loudspeakers by Voight in the 1920’s, but the application to a diffuser of this type is novel and subject of a patent application.
The BassTrax™ Tractrix profile is known to maintain a 90 degree angle at each intersection of the expanding wavefront, thus avoiding reflections. This clever arrangement also makes the loudspeaker less critical of room positioning.
ENCLOSURE: The high density birch ply construction is pressed to ensure an extremely rigid and low colouration structure. The drive unit is coupled to internal bracing panels through damping material to absorb energy. The high mass machined aluminium platform, provides exceptional stability for precise low frequency performance and resolution of fine detail and also is an integral part of the BassTrax™ diffuser system. Heavy duty support spikes, adjustable from above enable precise levelling, with the provision of machined aluminium cups for protection on wooden floors.
