Напольная акустика — Fyne Audio F703

The F703 is a UK-built floorstanding speaker in the F700 Series from Fyne Audio, a range that uses trickle-down technology from the company's F1 Series. It combines two cones, one inside an IsoFlare point source unit and one for bass in a hand-built cabinet, and Fyne presents it as a midsized floorstander. Fyne lists it at GBP 10,999.99 per pair, and it comes in white, black or walnut piano gloss.

Key specs that matter

The design is 2.5-way. The IsoFlare unit has a multi-fibre cone and FyneFlute surround, with a 75 mm titanium dome compression tweeter driven by a ferrite magnet mounted at its centre. The second 250 mm cone, also multi-fibre with a FyneFlute surround, handles bass. The crossover points are 200 Hz and 850 Hz. Fyne quotes 26 Hz to 26 kHz at -6 dB, typical in room, a sensitivity of 94 dB for 2.83 V at 1 m and an 8 ohm nominal impedance. Continuous power handling is 125 W RMS. Each speaker is 1180 mm tall, 438 mm wide and 464 mm deep, with a weight of 48.3 kg.

Engineering and use context

F700 cabinets are made from high density birch plywood, a material Fyne chose for its low resonance, braced extensively inside and tuned through two internal cavities. The reflex port exits through the cabinet floor onto a BassTrax diffuser built into the plinth, and its Tractrix profile spreads the bass output around the base. The plinth itself is machined aluminium, made of two 8 mm plates held apart by aluminium spacers. Floor coupling spikes carry large knurled lock rings for levelling, and machined aluminium cups protect wooden floors. The passive crossover is bi-wired and low loss, using 2nd-order low-pass and 1st-order high-pass filters, with Claritycap capacitors, Van den Hul silver-plated internal wiring and Cryo-Lite treatment. Gold-plated binding posts are joined by gold-plated link cables.

Pairing

Fyne gives a recommended amplifier range of 20 to 250 W RMS per channel. The low bottom figure reflects the high sensitivity, so modest amplifiers can be used, while the upper value suits more powerful solid-state designs. The bi-wired terminals also allow bi-amping. The IsoFlare layout places the tweeter coaxially at the centre of the upper cone, so treble and midrange come from the same point with constant directivity.

Alternatives

The Fyne Audio F702SP is a Special Production floorstander that brings F1 Series IsoFlare drivers and BassTrax porting into a curved cabinet, priced at GBP 11,999.99 per pair.
