A loudspeaker system for reproducing multichannel sound including a first sound and a second sound with an improved sound image in a listening zone such as a home theatre, said loudspeaker system including: a first speaker array for location in a first position relative to said listening zone, said first speaker array including a first radiating lobe for radiating said first sound of said multichannel sound and at least a second radiating lobe for radiating a delayed version of said first sound; a first sound modifying member configured to project into said listening zone for separating said first sound radiating lobe associated with said first sound of said multichannel sound from said second radiating lobe associated with said delayed version of said first sound; a second speaker array for location in a second position relative to said listening zone, said second speaker array including a first radiating lobe for radiating said second sound of said multichannel sound, and at least a second radiating lobe for radiating a delayed version of said second sound; a second sound modifying member configured to project into said listening zone for separating said first sound radiating lobe associated with said second sound of said multichannel sound from said second radiating lobe associated with said delayed version of said second sound; and means for generating said time delayed versions of said first and second sounds; wherein said first and second sound modifying members are arranged such that a listening position substantially equidistant from said first and second arrays is exposed to radiation from said second lobes or from said first lobes and a listening position not substantially equidistant from said first and second arrays is exposed to radiation from both said first lobe of one array and said second lobe of another array such that substantially all positions in said listening zone receive sound radiation from said first and second arrays with substantially equal arrival times. a first speaker array for location in a first position relative to said listening zone, said first speaker array including a first radiating lobe for radiating said first sound of said multichannel sound and at least a second radiating lobe for radiating a delayed version of said first sound; a first sound modifying member configured to project into said listening zone for separating said first sound radiating lobe associated with said first sound of said multichannel sound from said second radiating lobe associated with said delayed version of said first sound; a second speaker array for location in a second position relative to said listening zone, said second speaker array including a first radiating lobe for radiating said second sound of said multichannel sound, and at least a second radiating lobe for radiating a delayed version of said second sound; a second sound modifying member configured to project into said listening zone for separating said first sound radiating lobe associated with said second sound of said multichannel sound from said second radiating lobe associated with said delayed version of said second sound; and means for generating said time delayed versions of said first and second sounds; wherein said first and second sound modifying members are arranged such that a listening position substantially equidistant from said first and second arrays is exposed to radiation from said second lobes or from said first lobes and a listening position not substantially equidistant from said first and second arrays is exposed to radiation from both said first lobe of one array and said second lobe of another array such that substantially all positions in said listening zone receive sound radiation from said first and second arrays with substantially equal arrival times.
