Compact loudspeaker arrays using beamforming, such as the IKO (icosahedron, 20 loudspeakers) were introduced for composition of electroacoustic music with intentionally intense room excitation and interaction. It might be more intuitive classifying such compact arrays as musical instruments than typical multichannel loudspeaker domes, which often are referred to as technical tools within the compositional process. In this paper we would like to discuss the different artistic strategies and practices that come along with sparse knowledge about listening habits and abilities of audiences in the current performance environments, when using different loudspeaker arrays. By this we find criteria for the so called `shared perceptual space` (SPS). This shall be the artistic-scientific field that conjuncts conflicting strategies to effectively guide future research efforts.
