Fyne Audio F501S

Fyne Audio F501S: 2.5-way floorstanding speakers with a 150 mm IsoFlare driver

The F501S is a floorstander from the Fyne Audio F500S Series. The maker suggests it both for music listening and for home cinema. Sold as a pair.

The 150 mm IsoFlare point source unit, whose tweeter has a 25 mm magnesium dome, is joined by a 150 mm drive unit assigned to the bass. The patented BassTrax system with Tractrix diffuser, built into the cabinet, spreads bass evenly through 360 degrees and eases the problems of placing the speaker in the room. The cabinet is made of high-rigidity MDF, and a presence switch lets the listener adjust midrange detail.
