ABSTRACT
Chapter 11 discussed many aspects of the performance of loudspeakers in rooms. Principally, it was dealing with single loudspeakers, but a very important aspect of the performance of sound control rooms for music recording in the spacial performance in stereo or surround. This aspect of the performance of loudspeakers is difficult to specify, and in the case of a single loudspeaker, which is usually what loudspeaker specifications relate to, it is currently (2007) impossible to specify. Nevertheless, without knowing the basic behaviour of multiple loudspeakers it will be difficult to appreciate some of the more philosophical discussions that follow in later chapters. Let us now look at the behaviour of multiple loudspeakers in some detail. First, however, we must begin by once again considering mono sources.
