Abstract
A loudspeaker system () includes an overhead sound image generating (e.g., ATMOS™) elevation sound projecting loudspeaker transducer or array () for reproducing an elevation signal and a second cancellation loudspeaker or transducer array () for generating and projecting a direct signal cancellation. The cancellation speaker or array () is driven with a filtered, polarity reversed version of the elevation signal to cancel undesired direct sound () from elevation speaker () which would otherwise diminish the quality of elevation signal reproduction for a listener L.
