High quality stereo sound dispersion is obtained through the use of a speaker cabinet having three tiers of speakers which are effectively sound insulated from one another. The topmost and bottommost tiers have speakers which are oriented in divergent directions from one another, while the intermediate tier has speakers which are unidirectionally oriented. Horizontal sound panels are provided between the respective tiers of speakers to accomplish the sound insulating effect, and the speakers themselves are mounted in vertical panels which form walls associated with sound compartments. In this respect, the divergently oriented speakers are positioned within walls of triangularly shaped sound compartments, while the unidirectionally oriented speakers are contained within a wall of a rectangularly shaped sound compartment. The respective sound compartments are sealed airtight and are filled with acoustical fiber glass to create the desired sound enhancement characteristics. A felt material is provided as a covering over the horizontal sound panels so as to further modify the tonal effects of the projected sound.
