摘要: A sound radiator comprising at least four high frequency loudspeakers with their axes intersecting in zigzag relationship, and a single low frequency loudspeaker whose center is at a distance not more than 1.5 times the diameter of the low frequency loudspeaker from the center of that high frequency loudspeaker which is farthest from the low frequency loudspeaker. The wave length of the crossover frequency of the low frequency and high frequency loudspeakers is not more than the smallest dimension of the housing for the unit measured in a plane perpendicular to the axis of the low frequency loudspeaker. A perforated obstacle is disposed in front of part of the high frequency loudspeakers.
