Fyne Audio Vintage Fifteen

The Vintage Fifteen is the flagship of Fyne Audio's Vintage series — a full-size floorstanding loudspeaker built around a 380mm IsoFlare point-source driver with a 75mm titanium alloy dome compression tweeter and a neodymium magnet system. Frequency response extends from 22Hz to 26kHz, sensitivity is 97dB, and the recommended amplifier power range of 20–400W makes it compatible with everything from low-powered single-ended valve designs to the most powerful solid-state amplifiers available. At 92.9kg each, built from birch ply with oiled walnut and solid walnut trim, it is the most substantial expression of Fyne Audio's heritage design philosophy — and one of the most technically formidable loudspeakers available at any price.

The 380mm IsoFlare driver is the largest point-source unit Fyne Audio produce. At this diameter, the cone moves extraordinary volumes of air with minimal effort — which is why 97dB sensitivity is achievable alongside 22Hz bass extension. Most loudspeakers require a trade-off between efficiency and bass reach; the Vintage Fifteen does not.

IsoFlare Driver Technology

The IsoFlare driver combines the bass/midrange cone and the high-frequency compression tweeter on a shared axis — the tweeter fires from the centre of the bass/midrange driver — so both drivers radiate from the same point in space. Point-source behaviour means the time relationship between bass, mid, and treble is consistent across the entire listening area, and the dispersion pattern is isotropic — sound radiates evenly in all directions rather than beaming forward from a conventional tweeter.

In the Vintage Fifteen, the IsoFlare driver is a 380mm multi-fibre cone paired with a 75mm titanium alloy dome compression tweeter with a neodymium magnet system. The 75mm titanium dome handles far higher output levels with lower distortion than a 25mm dome driver — at the dynamic levels the Vintage Fifteen's 97dB sensitivity makes available, this matters considerably. The crossover divides at 750Hz, giving the IsoFlare a wide operating range that it manages with the composure that a driver of this mass and area is uniquely equipped to provide.

BassTrax and Cabinet

The downfiring port connects to a BassTrax Tractrix diffuser at the base. The Tractrix profile smooths the bass-to-room transition, reducing port colouration and floor-boundary reflection. The cabinet is birch ply with oiled walnut veneer and solid walnut trim, with extensive internal bracing — a construction method that combines structural rigidity with controlled damping and the visual warmth of natural wood. The Vintage Fifteen is a physically commanding piece of furniture as well as a loudspeaker.

High-Frequency and Presence Adjustments

The Vintage Fifteen includes rear-panel adjustment for high-frequency energy (750Hz–26kHz, ±3dB) and presence (2.5kHz–5kHz, ±3dB). These controls allow independent tonal fine-tuning to room acoustics and partnering equipment without external equalisation — a meaningful practical advantage in a speaker of this scale, where room interaction at both frequency extremes can be significant.

Technical Specifications

Who Is It For?

The Vintage Fifteen is for the listener with a large room, a serious system, and an appreciation for the heritage aesthetic of classic British loudspeaker design executed with contemporary engineering. At 97dB sensitivity, it will operate at full dynamic range from a modest amplifier — a 20-watt single-ended triode design will drive it to levels that fill a large room. At the same time, the 400W upper limit means high-powered solid-state amplification finds no ceiling. The 22Hz bass extension requires no subwoofer augmentation for any recorded music programme.

Those considering the Vintage Fifteen alongside the F1 series should hear both. The Vintage series brings a different acoustic and aesthetic character to the same core IsoFlare technology. The Fyne Audio Vintage Five is the compact standmount expression of the same design philosophy. For those interested in the largest F1 series floorstanders, the F1-12s and F1-10s are the natural comparisons within the F1 flagship range. The Fyne Audio SuperTrax super tweeter extends HF performance further still for those who wish to push the Vintage Fifteen's already considerable bandwidth.

Buying from Martins Hi-Fi

Martins Hi-Fi has been in Norwich since 1968. Elizabeth Gould runs the business today, and we stock only brands we have heard properly and stand behind. The Vintage Fifteen is available to discuss and audition at our Norwich showroom — at this level a demonstration is not optional, and we ask that you call ahead so we can give it the dedicated time it deserves. Dave and Chris can advise on amplifier matching, room requirements, and how the Vintage Fifteen sits relative to the rest of the Fyne Audio range.
