An improved three loudspeakers virtual reproduction system for 5.1 channel surround sound is presented. Firstly, it is pointed out that there are some defects in the current virtual reproduction system, including narrow listening area, instability in sound image, etc. Then, it is proved by theory and experiment that by using a pair of full band loudspeakers placed in front ±30° and a tweeter placed in front 0°, the sound image stability of the virtual reproduction system for 5.1 channel surround sound can be improved. This arrangement of loudspeakers is feasible and the signal processing procedure is simple. Therefore the improved system is suitable to be used in TV sets and multimedia computers.
