In this session, we will address how to solve some of the most common questions when designing audio systems: How many loudspeakers do I need? How far apart should they be placed? Which model is most suitable based on the space and project requirements? We will explore how to design effective solutions based on real-world needs, using AVIXA ACU standards and Bose Professional design guides as a reference. We will conduct a hands-on workshop where these concepts will be applied to reinforce learning and encourage active participation.
