F501SP Floorstanding Speakers By Fyne Audio

The Fyne Audio F501SP is a UK-built Special Production version of the award-winning F501 loudspeaker. Building on the outstanding sonic performance and aesthetics of the original model, the F501SP benefits extensively from technology developed for the premium F700 Series.

Compared to standard F500 Series loudspeakers, the most significant upgrade for Special Production models can be found in the new SP Isoflare drivers. Combining our engineer’s decades of driver design expertise with advanced computer modeling has resulted in a cutting-edge driver design that delivers a class-leading music listening experience. Offered in 6” (150mm) and 8” (200mm) variants, the SP Isoflare units borrow much of the technology developed for F700 models, including the F700’s 25mm magnesium diaphragm compression tweeter and multi-fiber cone with FyneFlute roll surround.

The centrally positioned HF unit uses a powerful neodymium motor system with a vented rear chamber to move fundamental resonance well below the crossover point. The unique HF waveguide has undergone extensive computer modeling to deliver an optimized wavefront expansion rate and flat frequency response out to its 30kHz design parameters. The HF system is efficiently cooled by heatsinking through a metal pole piece, ensuring a smooth HF response even after extended high volume listening.

The SP cone is created from a bespoke multi-fiber mix designed to give an extremely natural sound through the critical mid-band region along with the required stiffness to drive low-frequency transients with minimal coloration. Set in a bespoke rigid cast aluminum chassis, the LF motor system incorporates a separate flux focusing magnet to increase low-frequency efficiency and maintain a flat response through low bass frequencies. The LF cone is terminated with a FyneFlute roll surround, offering significant benefits in terminating unwanted cone energy over typical rounded profile surrounds.

At the heart of all SP Series loudspeakers is the award-winning F500 Series cabinets, enhanced with subtle improvements to further refine performance. SP models use a higher density fibreboard to increase rigidity, plus a balanced combination of bonded acoustic fiber and polyether foam damping to control resonances. The parallel-sided heavyweight construction is internally braced to further lower coloration. The concept extends to the driver/cabinet interface, the rear of each drive unit being coupled to the bracing spars with an energy-absorbing damping mastic.

BASSTRAX^TM PORT SYSTEM

All three SP models incorporate Fyne’s flagship BassTrax Tractrix bass porting system as found in a larger format on the F700 and flagship F1 models. The system integrates a tuned downward-firing port and Tractrix profile cone that converts plain wave port energy into a spherical 360-degree wavefront that exits uniformly through the plinth. The system smooths LF output by evenly dispersing energy into the room, making the speaker much less critical of room positioning.

CROSSOVER

With many crossover components and circuit architecture trickled down from the premium F700 loudspeakers, F500 SP models bring a new level of refinement and detail to the already successful F500 design. Low-loss laminated core inductors, high-grade polypropylene capacitors, and Van Den Hul Matched Crystal silver-plated OFC wiring ensure transparent signal transmission, with final crossover and component tuning undertaken by Dr. Paul Mills. The F500 SP Series integrate Fyne’s high-quality bi-wire terminal panel with a fifth loudspeaker terminal for driver chassis grounding.

PLINTH

Optimizing floor coupling and better dissipating vibration in the F500 Series cabinets, floorstanding SP models use Fyne’s striking twin-layer metal plinth. Machined from thick aluminum plates, the two sections are precisely separated by aluminum spacers for optimum integration with the BassTrax porting system. 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.
