Loudspeaker Products


The perfect loudspeaker series for elegant, architectural room integration and for mobile use. Sophisticatedly developed with all-round convincing sound characteristics, even in acoustically difficult environments.



Large yet compact

With an impressive reach and considerable depth, the K&F PASSIO is incomparable. By using the two 5″ chassis in a D’Appolito arrangement, there is much more membrane surface available than there is with systems with a 6.5″ chassis. This makes the accessory very small, at least for the spectator. For the user, however, it is great. The acoustic impression is also great; it rapidly sparks passion. Over the entire frequency band – no clinking, no warping. Everything remains neutral and natural, regardless of whether it is loud or quiet. The K&F PASSIO is also excellent in delivering almost unbelievable sound pressure levels. Truly great!

Black as night

In physics, black means the absence of (visible) light of any wavelength. Practically invisible. Like PASSIO itself. Does not pile on – neither the concealed accessory and connection field nor the lean design with the 5° inclination to the ceiling and floor. Hidden passion!

Even deeper

The PASSIO SUB 12 and PASSIO SUB 15 are the ideal bass extension for the PASSIO series and are equally suitable for combinations with the GRAVIS and SONA Series. PASSIO subwoofers are characterised by low weight and dimensions, an integrated, passive crossover and high degree of efficiency. Dominant combination!
