An apparatus that provides for the reproduction of 6.1 surround sound (or other formats of) audio programs using a minimum of two speaker cluster locations is disclosed. The current invention accurately produces surround sound effects with speakers in only two locations in lieu of the conventional six. A sub-woofer, in its normal configuration, can be used with the invention if desired. The left front, rear center, rear left and center signals are produced from a left cluster array. The right front, rear center, rear right and center signals are produced from a right cluster array. This configuration eliminates the need for a center speaker and for rear speakers. Such elimination of speaker locations, along with their associated wiring, produces a less cluttered look, and lends itself to use in listening rooms of smaller size.
