<p>A loudspeaker combination comprises a rectangular casing having mounted on its top wall a midfrequency speaker and two or more high frequency speaker devices. The midfrequency speaker is oriented generally upwardly with an angle of declination of less than 45 DEG from the vertical. The high frequency speakers are oriented generally horizontally, with a slightly upward inclination. The axis of the midfrequency speaker and of at least one of the high frequency speakers are slanted sideways in the same general direction. This latter speaker or speakers radiates at least substantially one-half of the total high frequency sound energy of the loudspeaker combination. The remaining high frequency speaker or speakers radiate in different directions, preferably toward an adjacent wall or walls. In one embodiment the midfrequency speaker device also radiates low frequency sound; in another, a separate low frequency speaker device is provided. Two of such speaker combinations, mirror images of each other and widely spaced laterally from each other, provide a stereophonic system.</p> |
