ACADEMY SOVRAN 3 way Floorstanding / 2 Pieces The first three-way loudspeaker system able to control energy diffusion at low frequencies, using Chario Loudspeakers prioprietary Doublet adiation principle. A decisive step ahead, laying the theoretical foundations for a different approach to sound issues in small environments. Natural wood changes shape depending on ambient temperature and relative humidity. In other words, it adapts to climate conditions, generating outright tensions inside its fibres, which modify the macroscopic layout. This fact is well-known to master cabinet-makers, who actually adapt techniques when assembling the various parts of any prized solid wood cabinet. Firstly, the right board has to be chosen and cut using precise criteria to avoid creating isolated and incompatible sections. Secondly, the right storage area and drying process are defined for the rough wood. Thirdly and lastly, the sections are assembled in a precise order, to allow the moisture-absorbing capacity of each element to develop over time, settling to achieve soundness, not breakage. That’s why the CNC machines only cut and mill. The rest is time-honoured craftsmanship… Handcrafted Natural wood changes shape depending on ambient temperature and relative humidity.

The rest is time-honoured craftsmanship … The Acoustic Doublet The Acoustic Doublet proprietary theory that was developed for the Academy Sovran project allows even small-scale systems to use speaker/room interferences that will give listeners wave-fronts containing spatial information. This type of information is linked to the size of the source and length of wave emitted and it’s unlikely to be conveyed to the listener by bookshelf loudspeakers, since a physical distance of at least 1m is needed between sources. This is one of several reasons why Sovran adopts Reversed Woofer/ Tweeter Alignment, which keeps the woofer as far as possible from the subwoofer and at the same time provides the best angle for modelling the energy response around the second crossover region HOURGLASS DUCT Academy Sovran The pressure that pushes the air inside the reflex duct is extremely high. To view the phenomenon you can exploit the analogy of hydraulic lines that push the water upward. As the salt loses fluid pressure and this in turn reduces the speed, turning a powerful jet and turbulent in a weak jet and silent. Similarly, to the air in a reflex duct at a high speed of the particles corresponds to a whirling motion, while a low speed of the particles ensures a laminar flow silent. Obviously it is not advisable to reduce excessive air velocity, otherwise it also reduces the power of the acoustic wave emitted, renducing the action of the reflex port. The theory itself as a maximum value of 130 km/h because they do not occur disturbances worthy of note, suggesting at the same time a duct with a cross section increasing at the ends.
