To obviate to the poor efficiency and to the reduced power handling of the low range, which is typical of the dipole load, the designers have used two 12" high efficiency Beima woofers with differentiated filters.
In the back, the shape of the cabinet consents to the minimum loss in efficiency and the light front horn load on the woofers improves the efficiency of the acoustic emission in the mid-low and mid range, contributing in a significant measure to the outcome, which is of great sound realism.



The cabinet has been made using the Clad 58, a conglomerate formulated by Diesis Audio and composed of mineral powder and resins. Poured in liquid form into a single mould, once solid it assures more rigidity and damping than the wooden cabinets whose vibrations make disperse a lot of the sound level that a dipole can give back.

In order to get more solidity in matching the woofers (the vibrant elements) with the structure where they are inserted (cabinet), they have been blocked inside a notch (with the interposition of a PVC gauge) with a 20 tenths thick stainless plate. The plate has then been fixed through nine M8 bolts screwed into nine sockets inserted in the Clad 58. The plate, damped by a leatherette layer, pushes on the entire surface of the loudspeaker flange and assures a good contact continuity of the parts.




The use of the German BMS coaxial compression driver has made possible, with one horn only, a coherent and linear emission from about 600 to 25.000 Hz.
The horn shape and its radius of curvature consent the obtainment of a great dispersion also out of axis - confirmed during the listening tests - and a regular response of the drivers. Amazingly realized in Corian, a solid surface material created by DuPont whose primary use is in home furnishing and architecture, this material has been chosen because compact and solid. Realized in such material, the horn is only six millimetres thick.

The Corian can also be perfectly smoothed becoming capable of an extremely quick and precise emission since it is not altered by refractions and this is a very important thing when the frequencies that have to be emitted are so short as happens in the mid and high range.

The boards have been realized in 10 mm PVC by numerically controlled machines to use the connection cable as wiring cables. This operation has been made to avoid any contact resistances that are typical of the traditional fibreglass boards and to get a better signal transport.

Besides the Audin Cap and Mundorf Silver Gold capacitors and the Mundorf OFC Copper Foil coils, the other components are of high quality and there is no electrolytic capacitor that is bipolarized or in parallel to the signal.
