  • Patent number: 4267405
    Abstract: A stereo speaker system adapted for home use is arranged to increase stereo image perception by reducing spurious and confusing sound images. The speaker system includes a pair of low frequency speaker assemblies and a pair of high frequency speaker assemblies. The pair of low frequency speaker assemblies can be constructed along conventional lines although a columnar arrangement of speakers or acoustic transducers is preferred and preferably arranged to handle acoustic energy in a frequency range below 1000 Hz. The remaining portion of the speaker system includes a pair of high frequency speaker assemblies. Each assembly consists of a single column arrangement of a plurality of acoustic transducers or speakers; in one preferred embodiment, 24 high frequency speakers are included.
