Abstract:

The influence of power response of a loudspeaker system on sound quality and intelligibility is an often overlooked aspect of a speaker system's performance. This paper will examine the importance of achieving uniformly predictable power response and directivity and the factors leading to a successful design. Traditional axial response, beamwidth, and directivity plots fail to convey a complete information set. Data sets from traditional and recent designs will be compared to demonstrate the important factors and the means of identifying them in proposed products. This will be examined for a range of loudspeaker system sizes and applications.
