Fyne Audio’s F502SPs are a vivid listening experience. Massive bass and a fast, forward midband make for a sound few other loudspeakers come close to.

The F502 floorstanding speaker delivers the series’ signature clarity and articulation along with visceral bass. The system will suit larger listening environments but is capable of revealing a huge dynamic range even when played at low volumes in smaller rooms. Isotropic energy radiation, with point source constant directivity, is provided by a 200mm (8″) proprietary IsoFlareTM driver for outstanding stereo imaging, even off axis. A matched 200mm (8″) bass driver is also fitted to the 64-litre cabinet ensuring a breath-taking Hi-Fi or home theatre experience. Ideal for medium to large-sized rooms, the F502 is supplied with a dedicated plinth incorporating our BassTraxTM Tractrix diffuser system, which integrates bass energy uniformly into the room. The luxuriously finished, contemporary styled cabinet is available in a choice of dark oak or black oak real wood veneer and piano gloss black or white. Enhancing its aesthetic appeal, it has a gently curved front and rear baffle which additionally benefits the acoustic performance by reducing colouration effects.

Let us talk bass, since it forms a weighty part of this ‘speakers design essence and sonic character. The fibreboard cabinet, braced for rigidity, has a “conical Tractrix profile bass diffuser” we are told, that fires downward to a port on the bottom panel – think downward firing cone. Like all loudspeakers with downward firing ports the F502SP has a plinth that lifts it off the floor, in this case a substantial one of cast aluminium with adjustable spikes, twiddled by a supplied tool. ‘Tractrix’ refers to a horn profile developed long ago as optimal by Paul Voight and we described it in our Nov 94 DIY Supplement; Wikipedia has a very interesting explanation with animated diagrams. Klipsch also like to mention use of the Tractrix profile, so it well respected.

Fyne Audio are saying then that they use this optimum profile for bass port that loads the lower 200m drive unit.

Above the bass unit lies their 200mm Isoflare concentric drive unit with magnesium dome treble unit at centre, firing out through a short horn. The treble unit plays a strong role in the F502SP I found, coming in at 1.7kHz Fyne say – and our measurements show the ‘speaker is forward at this frequency and above, making for strong projection of detail. Think vivid vocals.
