Many years of experience in making speakers, mathematical modeling of sound processes and a special technique of sound quality evaluation predetermined the appearance of unique loudspeakers. While mathematical modeling helps to set the required parameters of speakers, acoustic design and separation filters, the proper method allows to assess the sound quality in the most accurate way.

We managed to create a very advanced design of the speaker, which was called Siegfried after the main character of Wagner opera. The main features of this design (Diffusor holder with two stiffeners of bell metal, paper cone, NEOMAX magnet, layered voice coil, etc.) with some modifications applied in all types of speakers: in the bass, mid and high frequency ones.


METROPOLITAN flagship model, which has the widest frequency response in the bass and treble, allowing a virtually natural sound that's as close to the sound of a real orchestra.

METROPOLITAN is intended primarily for use in medium and large rooms with volume up to 500 cubic meters.

  • weight of one AS: 118 kg


SIEGFRIED drivers use traditional technology with paper diffuser made of special pulp, suede suspension, multilayer coil. It is enhanced with Neodyne magnet, the most modern element to supplement the timeless solutions.Made of the bell bronze diffuser holder positively differs from aluminium one. All of components impose a noble imprint on the sound of the dynamic head. Siegfried is a hand-made speakers family, for midrange, for high and low bands.


Acoustic system MARIINSKY is smaller, but it sounds similar to the flagship model METROPOLITAN.
