Fyne Audio F500SP Bespoke RAL Classic Colour

The Fyne Audio F500SP is the standmount entry point into the Special Production range — a UK-exclusive 2-way design that takes the F500's compact enclosure and applies a comprehensive set of SP engineering upgrades that separate it decisively from the standard S Series specification beneath it. In its bespoke RAL Classic colour finish, it is available only through selected Fyne Audio dealers, configured to order from the full RAL Classic palette and finished to the same high-gloss standard as the Piano Gloss range. For the buyer who needs a compact standmount but wants the engineering rigour of the SP Series — and who wants that speaker to belong in their interior with the same precision as the rest of their room — the F500SP in bespoke RAL finish is the most considered configuration available.

As the smallest loudspeaker in the SP Series, the F500SP does not compromise on the engineering that defines the SP designation. The 150mm SP IsoFlare driver is shared with the F501SP floorstander — the same twin-magnet motor, the same FyneFlute roll surround, the same 25mm magnesium dome compression tweeter. The BassTrax Tractrix diffuser is a direct derivation from the F700 Series rather than a scaled-down version of a larger design. The upgraded crossover integrates the driver more precisely within the existing cabinet volume than the standard S Series crossover, and a fifth binding post grounds the driver chassis directly — reducing RF interference in the circuit, and reflecting the engineering thoroughness that characterises the SP range at every level of the specification.

SP IsoFlare Driver Technology

The IsoFlare driver combines the bass/midrange cone and the high-frequency compression tweeter on a shared axis — the tweeter fires from the centre of the bass/midrange cone — so both drivers radiate sound from the same point in space. This point-source behaviour produces consistent time alignment across the listening area and off-axis coherence that a conventional separated-driver arrangement cannot replicate. The imaging stability and tonal consistency that result are the qualities that most directly separate the SP Series from the S Series it builds upon, and in the F500SP they are present in full — in a cabinet that occupies a genuinely compact footprint.

The SP IsoFlare driver uses a twin-magnet motor system and FyneFlute roll surround. The FyneFlute surround geometry reduces cone resonances at the driver termination — the point where the cone meets the surround — which affects transient accuracy and midrange clarity in ways that are audible on complex musical material at realistic listening levels. The twin-magnet motor provides a more linear magnetic field across the driver's excursion range, reducing distortion at the frequencies where the bass/midrange cone is working hardest.

BassTrax Tractrix Diffuser and Aluminium Sandwich Plinth

Low frequencies are channelled downward through Fyne's BassTrax Tractrix diffuser, built into the anodised machined aluminium plinth. The Tractrix profile maintains a consistent expansion angle as bass energy exits the port, reducing port-exit reflections and smoothing the transition between port output and room. This gives the F500SP better immunity to rear-wall boundary effects than a conventional rear-ported standmount of comparable size — a practical advantage in domestic installations where ideal placement is not always achievable.

Upgraded Crossover and Fifth Terminal

The SP crossover integrates the IsoFlare driver more precisely within the existing cabinet volume than the standard S Series crossover. The fifth terminal on the bi-wire connection panel grounds the driver chassis, reducing RF interference in the circuit — a detail consistent across the SP range and one that reflects Fyne Audio's engineering thoroughness at this level. The bi-wire configuration allows separate amplification of the bass and mid/treble sections for those who want to explore that approach.

The RAL Classic Colour Process

RAL Classic is the internationally recognised colour standard used across architecture, product design, and industrial finishing. The F500SP bespoke finish applies the full RAL Classic palette — several hundred defined colours, from understated neutrals to strongly saturated hues — to the same high-gloss cabinet finishing process as the standard Piano Gloss range. The bespoke colour option is available exclusively to the UK market through selected dealers including Martins Hi-Fi.

Lead times for bespoke colour finishes are longer than standard stock items. We can show RAL Classic colour swatches in our Norwich showroom and discuss how different colours read under different lighting conditions — which matters considerably when specifying a finish for a domestic installation where the light changes across the day. We work with you through the full process: initial colour selection, specification confirmation, and final delivery.

Technical Specifications

Who Is It For?

The F500SP in bespoke RAL finish is for the buyer who needs a compact standmount but wants SP Series engineering — twin-magnet IsoFlare driver, BassTrax aluminium plinth, upgraded crossover — rather than S Series specification. It is also for the buyer who wants a speaker finished in a specific colour that integrates with their interior, rather than choosing from a standard palette. The compact dimensions make it suitable for smaller rooms, desktop installations, or near-field listening positions where a floorstander would be physically inappropriate.

For those who want the SP standmount experience with the added bass authority and dynamic headroom of a floorstanding cabinet, the Fyne Audio F501SP Bespoke RAL Classic Colour Finish shares the same 150mm SP IsoFlare driver in a 2.5-way floorstanding enclosure. The Fyne Audio F704SP is the SP Series flagship for those whose ambitions extend to the twin 300mm driver architecture. The Fyne Audio SuperTrax is the natural high-frequency complement to any SP Series system, and the Fyne Audio F5S is worth considering for buyers who want S Series standmount performance in a similarly compact format at a lower price point.
