The heart of the F501SP is the IsoFlare point source driver, featuring a 150mm (6") multi-fiber bass/midrange cone with a FyneFlute surround, combined with a 25mm magnesium dome compression tweeter. The crossover has been upgraded to seamlessly blend these drivers with the F501 cabinet. The SP version also introduces Fyne's distinctive aluminum sandwich plinth, providing greater stability and further enhancing the BassTrax downward-firing porting system.
The connection panel has seen improvements as well, now including a fifth terminal designed to ground the driver chassis, reducing the impact of radio frequency interference in the circuit. Celebrating this unique UK Special Production model, the F501SP boasts enhanced aesthetics, featuring diamond machine-cut accents on the aluminum driver chassis, an anodized machined aluminum plinth, and the option of a Piano Gloss Walnut real wood veneer finish.
