High-fidelity/high-end loudspeaker Sigma 2

Sigma 2 takes after Sigma 4 as much as it is possible. Detail, weight, microdynamics. Sound naturalness and time-accurateness. Great sound stage and space.

Two midwoofers similar to those used for Sigma 4, were chosen now in a layout referring to the concept of D'Appolito. They create some sort of point source along with the same horn-loaded tweeter. Similarly, Sigma 2 curved structure focuses the sound at listening area.

And what more can be said about this loudspeaker? "There is no room for compromise here."

Sigma 2 enjoys a very high interest and becomes a desired loudspeaker after the listening session.
