Description
The F501S is the compact floorstanding model in the F500S series, featuring a 2½-way configuration that incorporates a dedicated bass driver alongside the 150 mm IsoFlare point source transducer with a 25 mm magnesium dome compression tweeter. This combination enhances frequency response and dynamic capability compared to the series' monitors, while maintaining the image coherence inherent to the point source design. The enclosure utilises a downward-firing port and the Tractrix BassTrax diffuser to distribute bass evenly throughout the room. Constructed from high-rigidity MDF with extensive internal bracing, it includes a presence control to adjust mid-band balance. It is a versatile column for two-channel high-fidelity systems and as a front channel in a home cinema setup.

Before choosing this model
The F501S combines a 150 mm IsoFlare driver and a dedicated 150 mm bass driver in a 2½-way floorstander. Its dimensions are 984 × 250 × 317 mm, excluding spikes. If you are moving from standmounts to floorstanders, compare the total space each format needs and its distance from walls. BassTrax does not remove the influence of room acoustics.
Fyne recommends an amplifier rated at 30–150 W RMS. This range is a starting point: tell us your amplifier model, listening distance and usual volume so we can discuss the pairing.

Technologies
Three Fyne Audio solutions work together to focus the image, control the bass, and reduce resonances.
- IsoFlare
IsoFlare is Fyne Audio's point source principle: the bass/midrange and treble share a common central point, ensuring the sound emanates from a single location. The aim is to achieve a coherent and stable image across a wide listening area.
- BassTrax
BassTrax is Fyne Audio's bass diffusion system based on a tractrix profile. It manages the low-frequency output of the loudspeaker to distribute bass energy more evenly throughout the room.
- FyneFlute
FyneFlute is Fyne Audio's cone suspension/termination technology. It addresses the behaviour of the cone edge to manage unwanted resonances within the speaker's operating range.
