1. A directional loudspeaker system comprising:

  • a cabinet having a substantially closeD lower compartment having a baffle board at the front thereof and a separate generally open-sided upper compartment, a first loudspeaker driver for the low frequency range mounted on the front baffle board of said lower compartment to cause sound emanating therefrom to be essentially omnidirectional, a generally planar baffle having substantially parallel upper and lower edges of unequal length joined by side edges supported vertically within said upper compartment and mounted for rotational adjustment relative to the cabinet about a generally vertical axis, and at least a second loudspeaker driver for a frequency range above the frequency range of said first loudspeaker driver mounted on said baffle at a location as to constitute with a portion of the baffle a dipole radiator having an angle of directivity generally perpendicular to the plane of said baffle, whereby the angle of directivity of said second loudspeaker driver can be varied relative to the cabinet as desired.
