The Genuin FS 2 has some variations to our concept: bass reflex directed to the ground. This is a concept shared between the Gran Gioia and the Genuin FS 2: borne trough a common development. Having the bass reflex directed to the ground moves much more air than a traditional bass reflex and much more involving and less intrusive is the power of the bass due to the much bigger activated surface. Changing the height to the ground the Genuin FS 2 allows to change the way the bass is playing according to the needs of the room and the personal tastes. The Speaker includes furthermore the possibility to align the mid high driver to the listening spot to get the best sound impression ever. Switchable cross over impedance correction and level adjustment complete the characteristics of the speaker to have it best driven by any kind of power amplifier.

The EAR - Article

  • Sitting still in my chair was not an option: the swing in the song moves my whole body and touches my heart.
  • Suddenly the drum solo arrives and the Blumenhofers go wild with a big, live sound.
  • No matter what you put into the Genuin FS 2, it will reproduce it with great ease, lots of detail, enthusiasm, a wide open stage and if needed a lot of subtlety. Each instrument is placed on its own spot and sounds the way it should do in its particular setting.
  • Expectations were high, because of the earlier listening sessions and all I can say is that they were fully met.

Audio-Activity - Article

  • The Nutcracker by Tchaikovsky, Kirov Orchestra, directed by Valery Gergiev (Philips) […] The violent finale of the “Intrada” of the “Pas de Deux” is reproduced with ease by the Blumenhofers. This is something that does not happen with the majority of the hi-fi components that we have in our houses!
  • These loudspeakers, despite the horns, are able to disappear and let the scene to music.
  • […] this is a device produced with care by someone that is not just an assembler […]
