Patent ID: 8542854

Claim:
A speaker system comprising: at least one speaker enclosure having a front face; a plurality of transducers mounted in the at least one speaker enclosure; at least two of said transducers forming a horizontally displaced array; a speaker input port; a controller operatively coupled with said speaker input port; said controller configured to provide high frequency signals to a high frequency transducer, wherein said high frequency transducer is a side firing transducer; said high frequency transducer being positioned in said enclosure so that the center line of a sound beam emitted from said enclosure is at an angle to said front face of said enclosure; wherein said controller is further configured to provide lower frequency signals to said transducers forming the horizontally displaced array to cause dipole beamforming; and wherein said low frequency signals are determined by dipole beamforming array quarter-wavelength spacing, wherein an array usable frequency region is within +/−2 octaves about the array center frequency f_c, where f_c=c/(4d).
