Active Radiating Factor (ARF) is an important parameter for evaluating the similarity between a real loudspeaker line array and the ideal continuous line source. Our previous paper dealt with the relation between ARF of the loudspeaker line array and the Differential chart of its Frequency Responses in two distances (FRD). In this paper, an improved way to estimate ARF of the loudspeaker line array by measuring on-axis frequency responses is introduced. Some further problems are discussed and experiment results are analyzed. The results may give some help to the loudspeaker array designers.
