Active Radiating Factor (ARF) is an important parameter to analyze the loudspeaker line array when considering the gap between each two transducers, especially for high-frequency horns. As ARF is desired to be as high as possible, the staggered arrangement of horns is introduced in this paper. The responses in vertical direction and horizontal direction are analyzed. Compared with the straight arrangement, the negative effects of gaps are reduced and responses are improved in simulation.
