Oleg Rullit field coil speaker unit

Interesting speaker system with high class field coil speaker unit made by Oleg Rullit. The owner of the system has tried the highest class of the Feastrex line of widerange drivers - D9eIII, but he prefers the Oleg Rullit's because it better renders musical intonations.
