The Special Production F501SP is a UK built version of the award-winning F501 loudspeaker.
UK Built Version of the Award Winning F501
Low Bass & Effortless Dynamics
Building on the outstanding sonic performance and aesthetics of the original model, the F501SP benefits extensively from technology developed for the premium F700 Series. The IsoFlare point source driver uses a 150mm (6”) multi-fibre bass / midrange cone with FyneFlute surround, coupled with the 25mm magnesium dome compression tweeter. With an upgraded crossover to seamlessly integrate the drivers with the F501 cabinet, the SP adds Fyne’s signature aluminium sandwich plinth to enhance stability and further refine the BassTrax downward firing porting system. The connection panel has also been upgraded and features a fifth terminal to ground the driver chassis and reduce the influence of RF interference in the circuit. Celebrating this UK Special Production with enhanced cosmetics, the F501SP benefits from diamond machine cut detailing on the aluminium driver chassis, an anodised machined aluminium plinth and the option of a Piano Gloss Walnut real wood veneer finish.

Meet the F500 Series
The F500 series is based around an IsoFlareTM point source drive unit; technology which our Technical Director, Dr. Paul Mills, is reknown for. Our technical team, responsible for the audio performance and mechanical build of this type of driver, have many decades of experience between them. Combining Fyne Audio’s IsoFlareTM driver into a rigid cabinet, with a cleverly designed porting system, ensures optimal in-room performance.
Floor standing models in the F500 series use a rigid MDF plinth with large floor coupling spikes giving stability to ensure well-controlled bass performance and further enhancing stereo imaging. Additionally, the spikes can be adjusted from above the plinth allowing easier levelling of the speaker. The cabinets are crafted using real wood veneers and are available in choice of Dark Oak, Black Oak, Piano Gloss Black and Piano Gloss White.
BASSTRAXTM PORT SYSTEM
The bookshelf and floorstanding models employ an internal, downwards-firing port system. Below the port, a Tractrix profile diffuser (patent applied for) converts plain wave port energy to a spherical 360-degree wave front, integrating energy uniformly into the room. This clever design ensures that the loudspeaker is less critical of room positioning.
Low-loss, laminated core inductors and audiophile-grade polypropylene capacitors are used exclusively throughout the F500 series crossovers. The result is an exceptionally clean signal path and very low crossover losses, ensuring the very best in detail resolution and musical communication.
The F500 range is as impressive with movies as it is music. FYNE AUDIO’s point source driver technology is ideal for articulating the finest of movie detail with pin-point accuracy. High efficiency and high-power handling means the F500 series delivers an incredibly dynamic and lifelike performance whether you are listening to DTS Master Audio or Dolby True HD.
Point Source Technology
Point source driver technology is not new to Fyne Audio. Our technical team, responsible for the audio performance and mechanical build of the driver, have many decades of experience between them. Our proprietary IsoFlareTM design ensures constant directivity of the wave front generated, providing outstanding stereo imaging, even off axis. Furthermore, a smooth and extended response is delivered thanks to the highly rigid titanium high frequency diaphragm which pushes the break up mode well above the level of human hearing.
Flat Frequency Response
To fully optimise the driver’s performance, every aspect of the meticulous design has been considered. A vented rear chamber in the Neodymium HF magnet places low frequency resonance well below crossover region. The unique geometry of the high frequency unit’s waveguide provides a flat frequency response and avoids internal reflections.
To eliminate unwanted vibrations, which would be detrimental to the sound quality, both the point source driver and the supplementary low frequency driver fitted to the floor standing models, are built around a rigid cast aluminium chassis. Multifibre paper cones are used providing natural sounding midrange and clean transient behaviour. Cone energy is then very effectively terminated using a fluted rubber surround.
Special Production (SP) models distil some of Fyne’s best components and engineering into a unique loudspeaker, optimised by our Technical Director Dr Paul Mills and hand built in the UK by our Special Projects team. Improving on the F502, the SP edition uses the premium 200mm (8in) IsoFlare™ driver and 200mm (8in) bass/mid driver from the F702, featuring rigid multi-fibre cones and FyneFlute™ roll surrounds. The IsoFlare’s 25mm magnesium compression tweeter has a unique HF wave guide pole piece delivering an incredibly even, full-range frequency response and outstanding musical imaging. The F502SP also benefits from the F700’s advanced crossover components and aluminium sandwich type plinth with BassTrax tractrix profile bass diffuser, re-engineered to precisely tune the F502SP’s more compact cabinet. The result is a stunning, bespoke addition to the F500 series, available in high-gloss black and high gloss white as standard, or in a new, luxurious deep gloss lacquered walnut veneer with diamond machine cut finish on the aluminium chassis.
