The award-winning F501 is the smaller of the two floorstanding speakers in the F500 Series, but is still able to deliver deep bass and effortless dynamics from a compact, small-scale enclosure. The 150mm (6") IsoFlare™ driver is accompanied by a matching 150mm (6") woofer, further enhancing the F500 Series' signature clarity and intelligibility. The IsoFlare™ driver delivers isotropic energy radiation with constant point source directivity, providing excellent stereo imaging, even off-axis. Ideal for small to medium sized rooms, the F501 comes with a custom plinth featuring our BassTrax™ Tractrix diffuser system, which distributes bass energy evenly throughout the room. The luxuriously crafted, modern housing is available in dark or black oak real wood veneer and black or white piano lacquer. It emphasizes its aesthetic effect and has a slightly curved front and rear baffle, which further improves playback by reducing discoloration effects.
