A speaker system features a plurality of transducers arranged to produce a sound field similar to that of an acoustic point source. The arrangement of transducers optimizes the sound field by reducing the sound energy directed towards the primary reflective surfaces within the room in which they are placed. In a preferred embodiment, four medium-size transducers (woofers) operate together to reproduce the low-range to mid-range frequencies with the woofers positioned so that no two woofers share a common vertical axis or a common horizontal axis, and so that the horizontal and vertical axes of the woofers are evenly spaced. Preferably a center of a fifth transducer, a high frequency tweeter, is placed at the center of a pattern formed by the center of the woofers. The fifth transducer is set at a depth within the enclosure that is at the same acoustic center as the acoustic center of the woofers.
