The midrange/tweeter is integrated in a D’Appolito type assembly. The low crossover frequency (650Hz) allows a speaker center distance exactly equal to one quarter of the wavelength, which is almost never the case in other systems. The drivers are also temporally aligned with respect to the positioning of the diaphragms in the depth plane.
The cabinet also represents a large part of the speaker’s performance. The cabinet is made in our workshop by pouring a highly powdered, fiber-reinforced ceramic mixture into a mold to produce a finished one-piece cabinet. All walls of the frame are at least 30mm thick. This material provides a very high level of inertia due to its ability to dissipate vibrations but also due to its high mass. A single bare frame weighs 45kg.
