The HF section uses a custom-made ribbon radiator, the movable system of which (aluminum foil) is only 7 g. The matching transformers for connecting the radiator are wound with silver wire on amorphous iron cores. The emitter, capable of operating up to a frequency of 100 kHz, is loaded on a short horn with an opening in the form of a tractrix, which has a wide and uniform radiation pattern in the absence of diffraction.

The bullet-shaped horn of the mid-range section (700 - 3000 Hz) is made of multilayer poplar plywood, has a tractrix-shaped opening and a wide and uniform directivity. The 102 mm dynamic driver with a titanium cone is equipped with a powerful magnet system weighing 11 kg. The matching transformer with switchable taps of the secondary winding makes it possible to adjust the speakers to the acoustics of a real room.

The bass section in the form of a ball with a diameter of 105 cm is also horn (tractrix) and operates from 110 to 700 Hz. It uses a lightweight 203 mm dynamic head with a moving system weight of only 13 g.

The freestanding active subwoofer section includes 2 x 381mm dynamic drivers with 34mm of travel in closed box acoustic design. It is powered by a powerful (400 W) class D amplifier in a separate housing, which also houses the filters of the 6S19P tube crossover, using high-quality passive components (capacitors with copper foil and polystyrene and Teflon dielectric.
