Geometry: 4 ways 5 units. The two low frequency radiators are compression - loaded and room - interfaced at the lower part of the rear of the enclosure. Above the "fusion" frequency the mid - high cardioids radiators reproduce the significant part of the spectrum, at the top section of the front of the cabinet.

The cabinet: is a rigid, triple arch - shaped, structure. The two lateral front cheeks are concave, while the woofer compressor is convex.

The tweeter: is a well - established and time proven 28 mm soft - dome unit, created by Ragnar Lian, one of the greatest Danish masters of transducer design.

The mid-range: array consists of two 4" units in a step - compensated, baffle, in a cardioids acoustic - resistance configuration, for the most accurate reproduction of the musical perspective. - The woofers: are two 9" metal cone, piston performance optimized units, in a compression - controlled and room - interfaced configuration

The crossover: is a mutational variable slope, coherent spatial radiation design.
