  • Patent number: 5216209
    Abstract: A loudspeaker system 10 and a method for disbursing sound waves are disclosed. The loudspeaker system 10 has a reflector screen 12 which is provided with a concave reflective surface 14. The reflective surface 14 is a complex curve having a central axis 16. A first speaker 18 is positioned in front of the reflective surface 14 a longitudinal distance along the central axis 16 less than a pre-determined distance x. The first speaker 18 projects sound waves above a pre-determined frequency toward the reflective surface 14 to be reflected and disbursed into a listening area. A second speaker 20 is positioned to project sound waves below the pre-determined frequency into the listening area generally. A frame 24 supports the first and second speakers 18,20. A method for disbursing sound waves is also disclosed including the steps of providing a reflector screen 12 having a concave reflective surface 14 and positioning first and second speakers 18,20.
