The Tempesta 17 is our complete proficiency entry level: it is able to convince both for music reproduction and cinema experience.

The Membran of the woofer is a new P2C® Sandwich-Membran consisting of 2 Peek® (
Victrex) sheets with carbon inlay. Its characteristic is high stiffness and no resonances in the application spectrum.
