The "stereo dipole" - A virtual source imaging system using two closely spaced loudspeakers

Abstract

A system comprising only two closely spaced loudspeakers can create very convincing virtual images around a single listener. It is demonstrated that such a system is very robust with respect to head movement, and that the processing does not introduce any excessive artifacts. In practice, the loudspeakers ought to be "pair matched" in order to ensure accurate imaging.</p
