The Fyne Audio F500SP are compact loudspeakers handmade in Scotland. This Special Production version adopts components and techniques from the F700 series, typically used on the brand’s high-end models.
IsoFlare architecture: mastering the point source
At the heart of the F500SP beats a 150 mm IsoFlare driver, a modern incarnation of the coaxial loudspeaker concept. This configuration places a 25 mm magnesium-dome compression tweeter at the exact center of the mid-bass driver, creating a single point source from which the full sound spectrum emanates. The tweeter, equipped with a powerful neodymium magnetic system, benefits from a rear chamber vented through the magnetic circuit, lowering its resonance frequency well below the crossover point set at 1.7 kHz.
The multi-fiber mid-bass cone features a distinctive FyneFlute surround, whose variable, fluted geometry efficiently dissipates edge energy at the cone periphery. This design drastically reduces parasitic resonances at the diaphragm termination. A double-magnet system, with an additional magnet positioned behind the main motor, concentrates magnetic flux in the voice-coil gap, significantly improving low-frequency performance.
The tweeter’s waveguide, machined from mild steel, features a geometry optimized by computer modeling to ensure a controlled wavefront expansion and a linear frequency response up to 30 kHz. A thermal dissipation system via a metallic pole piece guarantees stable response even during extended high-volume listening.
BassTrax Tractrix: innovation in the service of bass
The F500SP forgo the traditional bass-reflex port in favor of the BassTrax Tractrix system, a Fyne Audio hallmark technology. The port fires downward onto a conical diffuser with a tractrix profile mounted on a thick aluminum plate. This particular geometry, inspired by mathematical pursuit curves, converts the port’s energy into a 360-degree spherical wavefront that propagates evenly throughout the room.
This approach offers several major acoustic advantages. It minimizes wall interactions, making the speakers remarkably forgiving in room placement. The system maintains consistent low-frequency response, avoiding localized energy build-ups typical of conventional rear ports. The aluminum plate, coupled to the cabinet by four anodized aluminum feet, also provides excellent vibration dissipation.
British refinement down to the smallest details
Manufacturing of the F500SP at Fyne Audio’s Scottish factory follows a rigorous process in which each speaker is assembled by hand by the Special Projects team. The cabinet uses a fiberboard panel of higher density than the standard F500, with internal damping combining bonded acoustic fibers and polyether foam. The driver is mounted to a horizontal brace, concentrating its forces on the stiffest part of the structure.
The passive crossover benefits from selected components derived from the F700 series: low-loss laminated-core inductors, audiophile-grade polypropylene capacitors, and internal Van den Hul Matched Crystal silver-plated OFC copper wiring. The Cryo-Lite process applied to the wiring involves freezing to -170°C followed by a gradual thaw over several days, relieving micro-stresses in the material’s molecular structure.
The bi-wiring terminal incorporates a unique fifth binding post that allows the speaker’s metal chassis to be connected to ground, thereby eliminating RF interference potentially induced by the amplifier or cables. Protective grilles attach via hidden magnets, preserving the clean front baffle aesthetic where the driver chassis sports a diamond-cut aluminum finish.
Remarkable acoustic versatility
The F500SP excel in their ability to create a three-dimensional soundstage that transcends the cabinet’s physical limits. IsoFlare technology ensures constant directivity of the wavefront, preserving stereo image coherence even during off-axis listening. This characteristic greatly facilitates integration into varied listening spaces, from intimate small rooms to generously sized living areas.
With a sensitivity of 90 dB for 2.83 V at 1 meter and a nominal impedance of 8 ohms, the F500SP are compatible with a wide range of amplifiers, from modest-power tube electronics to more muscular solid-state designs. The recommended power range extends from 30 to 120 watts RMS, offering great flexibility in system matching.
The frequency response, extending from 42 Hz to 34 kHz (±6 dB in real-world conditions), attests to the breadth of the covered range. The compact dimensions (323 × 200 × 320 mm) conceal a surprising ability to reproduce the lowest octaves with authority and definition, while the top treble retains smoothness and refinement without ever veering into aggressiveness.

Mathieu
the speakers are very beautiful, very well made, and also locally in the United Kingdom, which I find important.
As for the sound, it is excellent: they are dynamic, with impressive bass for bookshelf speakers—tight and articulate; the mids are very good, with realistic vocals and lovely timbre; the highs stay smooth even at high volume; and the soundstage is excellent and very coherent. I’m delighted.
My setup: CXA81>Audioquest Rocket 44>Audioquest Thunderbird jumpers.

les enceintes sont très belles, très bien fabriquées, de plus localement au Royaume Uni ce que je trouve important.
Concernant le son il est excellent, elles sont dynamiques avec des basses impressionnantes pour des bibliothèques, tendues et articulées, les médiums sont très bons avec des voix réalistes et de beaux timbres, les aigus restent doux même à fort volume et la scène sonore est excellente, très cohérente. J’en suis ravie.

Superb speakers that exude quality.
The black lacquer finish is stunning, and the front grilles are magnetized, which is very practical. They’re easy to position thanks to the circular port located underneath the speaker. I was able to try them out on site with my vintage amp (thanks to the salesperson who kindly removed his banana plugs so I could connect directly). My wife and I were both impressed by the sound coming from these little boxes. After an hour and a half of relaxed listening, just the two of us, we left with them.
We’re delighted with the sound they deliver in our living room, even though they’re not on stands and not yet broken in.
Very happy with this purchase and with Home Ciné Solution, who don’t pressure you and give you all the listening time you need to make up your mind.

Superbes enceintes qui respirent la qualité .
Le laquage noir est magnifique, les caches avant sont aimantés donc très pratique ,elles ne sont pas difficile à positionner grâce a l’évent circulaire placé sous l’enceinte.j’ai pu les essayer sur place avec mon ampli vintage (merci au vendeur qui a gentille ment démonté ses fiches banane pour pouvoir brancher en directe dessus ) nous étions avec ma femme impressionné du son qui sortait de ces petites boîtes .au bout d’une heure trente d’écoute tranquille rien que tous les deux ,nous somme reparti avec.
Nous sommes ravi du son qu’elles procurent dans notre salon malgré qu’elles ne soient pas sur pieds et pas encore rodé.
Très content de cet achat et de home ciné solution qui ne vous mettent pas la pression et vous laissent le temps d’écoute nécessaire pour vous faire un avis.
