Description
The F501SP is the medium-sized floorstanding model in the F500 SP special production series, a British iteration of the F501 featuring technology inherited from the F700. Its IsoFlare point source driver utilises a 150mm multi-fibre bass/mid cone with FyneFlute surround, paired with a 25mm magnesium dome compression tweeter; this is complemented by a second 150mm multi-fibre bass cone in a 2.5-way configuration. With an upgraded crossover to integrate the drivers within the F501 cabinet, the SP version adds Fyne's signature aluminium sandwich plinth to enhance stability and refine the BassTrax down-firing port. The upgraded terminal panel includes a fifth ground terminal to reduce radio frequency interference. As a special British edition, it features cosmetic enhancements: diamond-machined aluminium chassis, anodised aluminium plinth, and four finishes, including Natural Walnut.
- 2.5-way configuration: 150 mm IsoFlare SP point source plus 150 mm multifibre auxiliary bass
- 25 mm magnesium dome compression tweeter with neodymium motor and FyneFlute suspension
- Downward-firing port with Tractrix BassTrax diffuser and aluminium sandwich plinth
- Enhanced filter with Cryo-Lite treatment and fifth grounding terminal
- Four finishes, including Natural Walnut; diamond-machined aluminium chassis

Before choosing this model
The F501SP is a Special Production model with a 150 mm IsoFlare driver, a 25 mm magnesium tweeter and a dedicated 150 mm bass driver. Its dimensions are 984 × 288 × 320 mm, excluding spikes. Check the available width for the plinth as well as cabinet height, and specify your preferred finish so the exact variant can be confirmed when you enquire.
Fyne recommends an amplifier rated at 30–180 W RMS. This range is a starting point: tell us your amplifier model, listening distance and usual volume so we can discuss the pairing.

Purchasing, listening and delivery
Ordering and system matching
Ask about the selected version and matching with your amplifier, sources and room. Supply arrangements will be confirmed in the quotation. An enquiry does not confirm a sale.
Listening sessions and demonstrations
You can request a listening session by appointment at our Barcelona office (Carrer de Modolell, 57). When we arrange the appointment we confirm which equipment is available to hear, along with the date and time.
Home demonstrations are not offered for this product.
Delivery and setup
Delivery, its cost and the estimated timing are confirmed in writing in your quotation, for your delivery address and before you accept it.
Installation and setup can be requested as an additional service. We assess feasibility and quote it separately.
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.

Choosing an amplifier for the F501SP
Start with the loudspeaker ratings and how you listen. Amplifier power, the electrical load, listening distance and musical peaks all matter when assessing a system.
Read the load and the test conditions
Nominal impedance is not a fixed resistance at every frequency. Fyne’s product specification does not give a minimum impedance or phase curve for the F501SP, so the nominal figure alone cannot establish how demanding the load is.
Compare amplifier output per channel at the same load, frequency range and distortion limit, and check how many channels were driven. For a valve amplifier, follow its manual when choosing the output tap. The volume-control position is not a power meter.
What the sensitivity figure means
The reference is voltage, not an unrestricted maximum sound level. In an ideal resistive calculation, 2.83 V corresponds to about 1 W at 8 Ω, but about 2 W at 4 Ω. Compare sensitivity ratings using the same reference and measurement conditions; real loudspeaker impedance varies with frequency.
Plan for distance and musical peaks
Measure the distance from each speaker to your listening position. For an ideal point source in free field, doubling that distance reduces the direct sound level by about 6 dB. Reflections and room modes mean that this is not a prediction of the level in your room.
Separate your usual sound-pressure level (SPL) from the peaks you want to reproduce. Headroom is the margin for those brief peaks before clipping. In an ideal linear system, an extra 3 dB requires roughly twice the power; 10 dB requires ten times the power. Driver limits and compression prevent this relationship from continuing indefinitely.
A room’s floor area does not prescribe amplifier wattage. Speaker and seat placement also affect the bass response. If a bass note disappears at the seat, investigate placement and room interaction before adding power or bass boost.
What to include in your enquiry
- Your amplifier’s exact model, output ratings and, where applicable, valve mode and output tap.
- Room length, width and height, openings, speaker-to-wall distances and listening distance.
- Your normal listening level, the music you use and whether you need more peak level or clearer bass at the seat.
- What you would like to check in a listening session, including your own amplifier if its use can be arranged.
Considering a Cary valve integrated? The SLI-80HS and SLI-100 product pages give output ratings and, for the SLI-80HS, operating modes. Those specifications are a starting point for a matching enquiry; they are not evidence of a tested F501SP pairing.
A listening-session request is subject to confirmation of the equipment, venue and date.
