Abstract
A quadrupole transducer created by spatially offsetting a first dipole from a second dipole while causing the first and second dipoles to produce the same acoustic signal. This arrangement minimizes floor, ceiling and wall reflections which alter the perception of sound quality. In some embodiments the second dipole is vertically offset from the first dipole. This produces a phantom acoustic image that is perceived to emanate from an intermediate position.
