Arraying and Rigging The MSL-10A loudspeaker is designed to function as a modular building block capable of being arrayed in multiples to satisfy a wide range of acoustical power and coverage requirements. Configured as a tightly controlled 30-degree section, the MSL-10A cabinet features a trapezoidal con- struction which forms curved arrays. MSL-10A’s in an array combine acoustically in a seamless fashion to form a radiating arc, producing uniform, coherent wavefronts over the angle subtended b
