Fyne Audio have built a reputation for speakers that combine genuine engineering innovation with a musical character that rewards long-term listening. The F700SP series — spanning five models from £3,499 to £19,999 per pair — applies the company's most advanced driver and cabinet technologies to a range designed for serious domestic listening. If you are weighing up which model to invest in, the question is not simply which is best. It is which is right for your room, your system, and the scale at which you want to listen.
Before considering what separates the models, it is worth understanding what unites them. At the heart of every SP speaker is Fyne Audio's proprietary IsoFlare point-source driver — a coaxial design that fires both bass and high-frequency information from the same point in space. Because both drivers share the same origin, the sound that reaches your ears is time-aligned in a way that conventional multi-driver arrangements cannot replicate. The result is coherence, precision imaging, and a natural tonal balance that defines the SP series character regardless of which model you choose.
The Fyne Audio F700SP is the entry point to the SP series and a standmount of genuine reference calibre. Compact in footprint but technically serious, it delivers the IsoFlare driver's characteristic coherence and imaging in a format suited to smaller rooms and those who prioritise midrange transparency and detail retrieval above outright scale. At this price, you are buying into the full SP series engineering philosophy — the step up from here is one of scale and dynamic authority, not character.
The Fyne Audio F701SP develops the standmount proposition with a larger cabinet and driver, bringing meaningfully greater bass extension and dynamic headroom. For listeners who want a standmount format but find the F700SP working against a larger room, the F701SP closes that gap considerably. The £3,000 step up buys a speaker that can fill more space naturally, without the need for a subwoofer, while retaining the precision and imaging that makes the SP series so engaging.
The Fyne Audio F702SP marks the transition to floorstanding design, and with it comes a significant increase in bass authority and dynamic scale. The larger cabinet volume allows the F702SP to pressurise a room in a way that standmounts — however capable — cannot fully replicate. For listeners making their first serious investment in a floorstanding speaker, or those moving up from a standmount system that has begun to feel constrained, the F702SP represents a genuine step change. The £5,500 increase over the F701SP buys not just more bass, but a more complete and self-sufficient speaker that demands less of the room.
The Fyne Audio F703SP builds on the F702SP with a larger, more refined cabinet and enhanced bass loading — a speaker designed for listeners with substantial rooms who want a floorstander that can fill the space with authority and control in equal measure. At £3,000 more than the F702SP, the F703SP delivers greater dynamic headroom and bass composure at volume, without ever losing the coherence and transparency that defines the SP range. It is the model for those who listen seriously and loudly.
The Fyne Audio F704SP is the fullest expression of everything the SP series stands for. At £5,000 more than the F703SP, it is an uncompromising floorstanding design that sets a standard few speakers at any price can challenge. For listeners with large rooms, reference-level amplification, and a commitment to hearing precisely what is on a recording, the F704SP is the model that leaves nothing on the table. It does not simply play louder than the F703SP — it controls the room more completely and resolves low-level detail at a level the models below it cannot match.
We strongly recommend an audition before committing at this level — the SP series rewards being heard in a properly set-up system. Contact us to arrange a demonstration and we can discuss which amplification will get the most from your chosen model.
