Installed Sound Technical Guide TA-7. Control of Lower-Midrange Version Directivity in Sound April, 2002. reinforcement Loudspeakers Using Crossover Overlap Techniques Summary Sound reinforcement and concert loudspeaker systems must satisfy many performance criteria in order to provide not only high fidelity reproduction, but also a high degree of intelligibility. Control of directivity and coverage is an integral and important part of the design of these systems in attaining their performance goals. This paper describes a technique to increase the lower-midrange directivity and decrease the vertical beamwidth of large Sound reinforcement speaker systems through crossover overlap. Rather than operate the individual low-, mid-, and high-range sections of the speaker independently in their own frequency bands, the new technique overlaps the operating frequency ranges of the low- and mid-range sections.
