The cabinetmaking structure consists mainly of high-density agglomerates (meditates). Obviously, the designers went on the hunt for vibrations since each finished speaker has a record weight of nearly 90 kilograms! The inner space is separated into two parts. A first closed volume loads the first bass speaker and the mid-high horn. The second speaker uses the principle of the transmission line, which means that the back wave is attenuated by a long path before opening out of the speaker. In the case of the Aéria Compact SII, the opening is practiced on the back and at the top of the speaker.

The filter has also been the subject of much care since the model used is symmetrical type second order (12 dB per octave) with generously sized components. This kit is available in several versions. The first includes the speakers, filter elements, terminal blocks, wiring and ... the speaker planes. Suffice to say that this version is only for those who master the work of wood. But, rest assured, there are other possibilities for cabinet making, accessible to any meticulous person.

For example, it is possible to acquire the speakers in the form of perfectly cut and machined panels (location of the loudspeakers and filters). The work comes down to a simple assembly with wood glue followed by a finish of his choice.
