Staggering a linear array of waveguides, as compared to a straight topology, offers an additional degree of freedom in optimizing the design for sound reinforcement applications. A comparison of staggered and straight arrangements reveals significant differences. Staggered arrays can have decreased sidelobes and reduced fluctuations in off-axis response. Smaller staggering intervals lead to wider horizontal coverage area. Within expected errors, the experimental data is consistent with simulation results with regard to such parameters as vertical directivity and frequency response smoothness.
