The types, sizes, and number of speakers needed will depend on the theater space and acoustics.

Explanation:

   The first written reference we have about acoustic studies dates from the first century BC. in materials where Vitruvius judges that the geometry of the Greek and Roman theaters was based on a previous study of acoustics, fan-explored Greeks, and arena Romans.

    But only in the twentieth century did scholars begin to understand how the shape and volume of the rooms influence the acoustic quality of the environment.

   The fact is that at all times, rooms were built with better or worse acoustics and those that generated more pleasant environments to the ears are those that resisted the most changes over time.

     It is quite clear that this exceptional performance of well-structured auditoriums is the result of an architecture designed together with acoustics as a unique process (architectural acoustics). In this way, the definition of shapes (geometry and volume) creates the basis of good acoustics, which becomes perfect with the choice of the best construction and finishing materials.
