Radiotehnika S-90 Speaker 3D model

Mid-poly model of the Radiotehnika S-90 acoustic system, for use in interior visualizations and game design.The model is made in the PBR pipeline (metalic \ roughness). A set of textures for the Unity engine.

Purpose and scope: for high-quality reproduction of music and speech programs in stationary household conditions. The S-90 speaker system, developed in 1975, is the first domestic system that meets the requirements of international documents for Hi-Fi equipment. Later models of this speaker S-90B and S-90D have an extended range of reproducible frequencies. Introduction of indication of electrical overload of loudspeakers and new appearance. Recommended power of a high quality consumer amplifier is 20 - 90 W. 35 АС-212 S-90 and 35 АС-012 S-90 are similar to АС, the difference is in GOST.
