Fyne Audio F501SP Floorstanding Loudspeaker (pair)

With 2 x 6" mid-bass drivers, 25 mm magnesium dome tweeter, down-firing bass port, and 91 dB sensitivity.

The Special Production F501SP is a UK-built version of the award-winning F501 loudspeaker. Building on the outstanding sonic performance and aesthetics of the original, the F501SP benefits extensively from technology developed for the premium F700 Series. The IsoFlare point source driver uses a 6”)multi-fiber bass/midrange cone with FyneFlute surround, coupled with the 25 mm magnesium dome compression tweeter.

With an upgraded crossover to seamlessly integrate the drivers with the F501 cabinet, the SP adds Fyne’s signature aluminum 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 aluminum driver chassis, an anodized machined aluminum plinth, and the option of a Piano Gloss Walnut real wood veneer finish.

More About Special Production

The 500 SP models use Fyne’s flagship BassTrax Tractrix bass porting system from the F700 and flagship F1 models.

With many crossover components and circuit architecture trickled down from the premium F700 loudspeakers, F500 SP models use low-loss laminated core inductors, high-grade polypropylene capacitors, and Van Den Hul Matched Crystal silver-plated OFC wiring enhanced by Fyne's Cryo-Lite process. The F500 SP Series also integrate Fyne’s high-quality bi-wire terminal panel with a fifth loudspeaker terminal for driver chassis grounding.

Floorstanding SP models use Fyne’s striking twin-layer metal plinth which is machined from thick aluminum plates. The integrated floor spikes are adjusted from the top of the plinth to make leveling easy, while knurled lock nuts clamp the spikes firmly in position. Machined aluminum cups are provided to protect wooden floors.

The most significant upgrade for Special Production models are the new SP Isoflare drivers. The SP Isoflare units borrow much of the technology developed for F700 models, including the F700’s 25 mm magnesium diaphragm compression tweeter and multi-fiber cone with FyneFlute roll surround.
