Chongqing Nanchuan Stadium is the largest and most advanced building project in Chongqing. It adopted the IQ10 10” coaxial speaker, which is installed on the pack way of the stadium. It has mid-long distance, precise localization and extremely high sensitivity, so that the sound can averagely cover each corner of stadium. 

     When holding the theatrical performance, it will simultaneously start to use the D-25 double 15-inch high-efficiency full-range speaker and the D-18B 18-inch subwoofer. With the corresponding power amplifier, it enables the entire facility to achieve a quite high sound pressure level.
