Past and current practice in this industry for measuring individual loudspeaker drive units has included great freedom in choice of chamber type and baffling. Many of these methods do not yield the true acoustical response of the loudspeaker free from acoustical artifacts.

This paper is intended to drive awareness of this issue in the industry in an effort to promote a new standard for measurement.
