Recent research shows that optimal surround sound reinforcement should consider a dual-target design of the direct sound: 0 dB per distance doubling (dod) to preserve the mixing balance at off-center listening positions and ?3 dB/dod to preserve the envelopment. To enable this, direct sound objects and the diffuse, enveloping parts of an immersive mix need to be processed separately on two mix buses. This requires high software and hardware efforts to implement both targets with a single loudspeaker system which begs the question: Can a single target achieve sufficiently acceptable reproduction, when considering a typical scenario composed of frontally panned direct sound objects and complementing surrounding effects? This contributions presets the results of a listening experiment using eight surrounding miniature line arrays in a 10.3m 12m room to answer the question.
