The first three-way loudspeaker system able to control energy diffusion at low frequencies, using Chario Loudspeakers proprietary Doublet  radiation 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 fibers, 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…

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
