FermatThe goal was to develop a loudspeaker with the bass sound pressure of the Fourier, the airiness of the Pascal and the efficiency of ... well, a yardstick still had to be found.

Ergo, lots of bass, high efficiency and airy tops.

Consequently, Dennis Frank and Peter Strassacker designed the following speaker. The Fermat is surely not a match for Nova 2 or Scan Speak Studio 12 with regards to presence, three-dimensionality and naturalness, but has a lot of power and an excellent efficiency.

Alcone AC15
Alcone AC 8 HE

The Fermat shows the following characteristics:
