The Fyne Detail: IsoFlare… Fine Audio’s IsoFlare driver is a point source system where the bass/midrange driver shares a common centre with the high-frequency unit. It provides outstanding stereo imaging, even off axis, as energy is radiated isotropically with constant directivity, following the flare of the driver cone. Sound is produced as if emanating from a single point in space. IsoFlare drivers can be found in all Fyne Audio loudspeakers from the F500 series upwards.
