AB  - This paper introduces an example of Electronic Shell acoustic enhancement system that was installed in a multi-purpose hall without an orchestra shell. The system is based on the concept of Active Field Control using electroacoustic means. The three objectives of this system were (1) the enhancement of early reflection for performers, (2) the increase of the reverberation time and the total sound energy on stage, and (3) the enhancement of early reflection in the audience area. The application of this system showed an improvement of about 1 to 2 dB in STearly and more than 2 dB in G in the audience area, which is equivalent or better performance than simple mobile typed orchestra shell.
