AbstractLive-sound subwoofer systems should deliver low-frequency sound evenly distributed throughout the audience area while simultaneously minimizing sound pressure levels on stage. Approximate solutions generally exploit cardioid subwoofers and/or steerable subwoofer clusters, yet require venue-specific manual fine tuning limited mainly by practical positioning issues. Enhanced live-sound systems are explored using a virtual three-dimensional acoustic space to model dominant venue characteristics. Specifically the Chameleon Subwoofer Array (CSA) is incorporated, already proposed as a solution to small-room low-frequency sound reproduction by extending the available degrees of freedom to control sound distribution in the target space. The CSA is adapted and scaled to match the large-scale dimensions typical of live events with 3-D simulation used to optimize and validate performance. Adaptation of existing industry-standard equipment with only minor modification is presented as a core feature.
