ABSTRACT:
An omnidirectional speaker system includes woofer and tweeter speakers mounted in a concave, curved upper fabricated of a relatively hard shell exterior and a foam interior, preferably plastic. Beneath the upper housing is a base, including a generally conical phase compensation plug which disperses the sound waves equally in all directions through a circumferential aperture between the upper housing and base. In a preferred embodiment, the cross-sectional shape of the upper housing is parabolic and the cross-sectional shape of the phase compensation plug is hyperbolic.
