Ivonne Atmojo, the owner, said that there are not many performance halls in Indonesia that have good acoustics. At the end of 2007, she and Hadi Sumoro, a member of Community Professional Loudspeaker's Technical Application Group (TAG), worked together planning the school's performance hall. Her main concern was to have good reverberation and even sound coverage, so that the audience could hear everything equally no matter where they sit in the hall.
Community SLS920 loudspeakers were chosen as the optimum solution due to their compact dimensions and with high power output with ideal dispersion pattern. Once installed and tuned, the loudspeakers proved to give crystal clear sound and even coverage throughout the audience area of the performance hall.
In addition to the main Community SLS920 loudspeakers, additional low frequency is added by a custom dual 12-inch subwoofer, designed by Atok Purnomo. The system is driven by Dynacord S-1200 and Absolute Design AD5000 and DJ1200 amplifiers with DSP processing by EV DC-One and dBx Driverack PA. The mixing console is a Yamaha MG24/14FX.
