Cabinet made in Strati (s)
The cabinet of the Stratis S1 is made up of layers (layers in italian STRATI - from which the series takes its name) to guarantee a higher stiffness than the classic parallelpiped.
The structure is completed by a reinforcement (to reduce internal resonances) and two counter-panels.
The front and rear panel are structurally separate units from the loudspeaker’s core, adjoined together thus enhancing the virtual magnitude of the sound. The front and rear panel covering is in Alcantara.
We also paid attention to time alignment of the drivers, the woofer is placed in front of the tweeter to align the emission of the moving coils.
The front Bass reflex duct drastically reduces the problems of positioning in the environment.
On the back of the speaker we find the Bi-wiring connections
Ultimate quality crossover components and the elimination of printed electronic circuits maximize the performance of this loudspeaker. On the STRATIS S1, we decide to use the simplest crossover possible: 6 db/oct. It is the simplest, but the hardest to design.
Use of a simple crossover will keep the musicality and dynamic qualities of the speaker.
