For the binaural virtual sound imaging systems that use two loudspeakers together with the crosstalk cancellation techniques, it has been shown that the system can deliver accurate binaural cues only when the setup and playback plant transfer functions are closely matched. There are many factors that make the playback HRTFs mismatch the setup ones, such as the difference between HRTFs of different individuals, the misalignment of the listener's head position and orientation, and the variation of the playback acoustics environment. This paper is going to investigate experimentally the effects of sound source spatial characteristics and misalignments on the performance of crosstalk cancellation systems. The factors that are going to be studied include the type of the sources, the spatial characteristics of the sources and positions of the sound sources. The results are useful for the design of the dynamic CTC systems where the relative angle between the loudspeakers’ orientation and the listener is not fixed, and in some practical applications such as spatial hearing experiments where high accurate binaural cues are required.
