Fyne Audio F501 Speakers

The award winning F501 is the smaller of the two floorstanding loudspeakers in the F500 series but capable of delivering low bass and effortless dynamics from a compact, small footprint cabinet. Bringing additional scale and power to the F500 series’ signature clarity and articulation, the 150mm (6″) proprietary IsoFlareTM driver is accompanied by a matched 150mm (6″) bass driver. The IsoFlareTM driver delivers isotropic energy radiation with point source constant directivity providing outstanding stereo imaging, even off axis. Ideal for small to medium-sized rooms, the F501 is supplied with a dedicated plinth incorporating our BassTraxTM Tractrix diffuser system, which integrates bass energy uniformly into the room

The luxuriously finished, contemporary styled cabinet is available in a choice of dark oak or black oak real wood veneer and piano gloss black or white. Enhancing its aesthetic appeal, it has a gently curved front and rear baffle which additionally benefits the acoustic performance by reducing colouration effects.

INNOVATORS OF FYNE TECHNOLOGY

OUR TECHNOLOGIES

Our experienced team of acoustic and mechanical design engineers have been in the loudspeaker business for very many years. Since coming together to form FYNE AUDIO, they have been busy honing their existing skills and developing technologies to ensure that we can offer best in class performance at all price levels.

ISOFLARE

ILLUSTRATING THE POINT

FYNE AUDIO’S IsoFlareTM 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 as if emanating from a single point in space.

ACOUSTIC EVOLUTION

Dr. Paul Mills, Fyne Audio’s Technical Director, has considerable experience with point source drivers. Furthermore our technical team, responsible for the audio performance and mechanical build of this type of driver, have many decades of experience between them.

MATERIAL FACTS

To fully optimise the driver’s performance, every aspect of the meticulous design has been considered. Eliminating unwanted vibrations, which would be detrimental to the sound quality, our IsoFlareTM point source drivers are built around a rigid cast aluminium chassis. Multifibre paper cones are used providing natural sounding midrange and clean transient behaviour.

SMALL DETAIL…BIG EFFECT

A vented rear chamber in the Neodymium HF magnet places low frequency resonance well below the crossover region. And pushing the break up mode well above the level of human hearing, the highly rigid titanium high frequency diaphragm delivers a smooth and extended response. The unique geometry of the high frequency unit’s waveguide provides a flat frequency response and avoids internal reflections.

BASSTRAX – TRACTRIX PROFILE DIFFUSER

WHERE AND WHY WE USE BASSTRAXTM

Bookshelf and floorstanding models from the F500 series up to the flagship F1 employ a downwards firing port system, and the floorstanding models use 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.

PERFECT ROOM INTEGRATION

Below the vent in the base of the loudspeaker, the BassTraxTM Tractrix profile diffuser (patent applied for) is used to convert the plain wave energy to an expanding spherical 360-degree wavefront, integrating energy uniformly into the room.

DESIGN PROFILE

This profile has been previously applied to horn loudspeakers by Voight in the 1920’s, but the application to a diffuser of this type is thought to be novel.

The BassTraxTM 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.

FYNEFLUTE

UNDERSTANDING THE ISSUE

With conventional driver surround profiles, at a specific frequency, energy can be reflected back down the cone, causing colouration.

ALL THINGS ARE NOT EQUAL

To provide a non-homogeneous interface, which very effectively terminates cone energy, we employ FyneFluteTM technology.

This variable geometry, within the computer designed fluting, eliminates mis-termination effects and reduces colouration, providing greater musical accuracy.
