The concept distils some of the very best components and engineering from across Fyne Audio’s high-end series into more affordable loudspeaker designs that set new benchmarks for performance at their price. Designed and tuned by Technical Director Dr Paul Mills, and hand built at Fyne’s UK factory, the F501SP and F502SP bring much of the driver, crossover and bass tuning expertise from the F700 and F1 series into the more compact and simpler F500 series cabinet design.
Using IsoFlareTM drivers derived from the F700 series, the Special Production models benefit from a premium magnesium dome HF diaphragm that delivers a better controlled and sweeter sounding top end response. The driver incorporates Fyne’s Flux Focussing System on the motor that creates high flux density in the voice coils for tighter bass and higher LF sensitivity. The multi- fibre cone and FyneFluteTM surround are manufactured from the same materials as the F700 series Isoflare drivers.
The SP models also incorporate Fyne’s Basstrax LF diffuser system with its Tractrix profile diffuser cone engineered into an aluminium sandwich plinth. This best integrates LF energy into the room making the speakers more tuneful and less critical of in-room positioning.
Other trickle-down enhancements over standard F500 models includes premium hand built crossover architecture and components, high- end silver plated Van Den Hul wiring and chassis earthing via a five terminal connection panel.
Special Production also brings enhancements to the cabinet construction, with each loudspeaker crafted from European sourced higher density cabinet boards and the interior integrating three complementary damping materials. Combined with the BassTrax porting system, SP models offer unrivalled smoothness in bass reproduction and vanishingly low distortion.
This comprehensive range of upgrades and enhancements to the original F500 series designs deliver sonic improvements across the frequency range and with a broad spectrum of musical material. From unearthing subtle details and instrumental nuances in chamber music to the crushing bass power of rock anthems, Fyne’s SP models are truly special.
