ABSTRACT:
An improved, compact speaker system for production of the full range of sound audible to the human ear, the sound radiating from the speaker being omnidirectional with the speaker including an outer cabinet shell and a defined chamber configuration within the shell. High and low frequency speakers are mounted within the cabinet shell with an acoustical path being defined within the cabinet for the low frequency wavelengths with the low frequency tones traveling within the cabinet for a distance of 1/12 the wavelength of the natural free air resonance of the low frequency speaker. The high frequency speaker having a slug of pre-determined surface configuration to permit omnidirectional sound radiation without distortion.
