Abstract:
A loudspeaker configuration capable of generating stereophonic sound separation from relatively loudspeaker drivers that are not necessarily widely separated. For example, such a loudspeaker configuration can be used to generate relatively good sound separation from a single chassis, such as a single speaker box, a boom box, a clock radio or the like. This can advantageously save space in many environments. One embodiment uses four mid-tweeter speaker drivers and a bass driver. The four mid-tweeter speaker drivers are arranged facing outward approximately 90 degrees apart from each other. A speaker driver facing the listener reproduces a mid channel signal, for example, L+R. A speaker driver facing away from the listener reproduces the same mid channel signal or a delayed version of the mid channel signal. A left facing speaker reproduces a side channel, for example, L−R. A right facing speaker reproduces a side channel, for example, R−L. The acoustic combination of the sound produced by the four speaker drivers creates a virtual left and right loudspeaker as experienced by the listener.
