Напольная акустика — Fyne Audio F704

The F704 is a floorstanding loudspeaker built in the UK by Fyne Audio as part of the F700 series. It borrows trickle down technology from the company's F1 Series and pairs a 300 mm IsoFlare point source unit plus a separate 300 mm multi-fibre bass driver in a twin cavity tuned cabinet. The UK price is GBP 13,999.99 per pair with VAT, which places it GBP 3,000 above the F703 of the same range.

Key specs that matter

Fyne Audio rates sensitivity at 96 dB for 2.83 V at 1 m and nominal impedance at 8 ohm. Frequency response runs from 24 Hz to 26 kHz, quoted at minus 6 dB and measured as typical in a room. The recommended amplifier range is 20 to 300 W RMS, continuous power handling is 150 W RMS and peak handling reaches 600 W. Each cabinet stands 1339 mm high, 540 mm wide and 561 mm deep and weighs 67.7 kg. Three finishes are offered, all in high gloss piano lacquer laid over a veneer base in black, white or walnut finish.

Engineering and use context

The system is a 2.5-way design. Inside the IsoFlare unit, the upper-bass and midrange diaphragm, a multi-fibre cone on a FyneFlute surround, encircles a 75 mm compression tweeter with a titanium dome and a ferrite magnet, which means both upper bands radiate from one point. The second driver shares the multi-fibre cone material and FyneFlute edge and handles only the lowest frequencies. Crossover points are set at 200 Hz and 900 Hz, with a 2nd order low pass and a 1st order high pass filter. The network follows a low loss passive topology with bi-wire terminals and has been given Cryo-Lite treatment. At the base, a down firing port opens onto a BassTrax Tractrix diffuser that is integrated with the twin cavity loading system, so no port opening faces the listener or the rear wall.

Pairing

The high sensitivity combined with an easy nominal load means modest amplifiers from the lower end of the recommendation can drive the F704, while the continuous handling leaves room for larger solid state designs. The bi-wired crossover lets the woofer and the IsoFlare section be fed by their own cables, which also allows bi-amping with two stereo amplifiers.

Alternatives

The Fyne Audio F703 sits one rung lower in the F700 range, with a 250 mm IsoFlare driver and a 250 mm bass cone in a 1180 mm tall cabinet weighing 48.3 kg, rated at 94 dB sensitivity.
