ABSTRACT:
A loudspeaker cabinet system wherein at least two low frequency drivers of equal effective diameters are critically spaced a vertical distance which equals the effective piston diameter of one driver times .pi.. When so placed, the respective spherical wave fronts of the drivers interfere causing a composite elliptical wave front which being flatter than the spheric can reflect from walls without drastically changing its shape to produce a uniform field which reaches the listener without producing any areas of the room which appear acoustically dead. Such system is especially useful in small rooms having reflective wall surfaces. Once the low frequency drivers are critically spaced and aligned, a higher frequency speaker or array of higher frequency speakers can be positioned thereabout without destroying the quality thereof.
