9. AND STACKING Overview The Aspect system flying hardware is specifically designed to take advantage of the precise horizontal directivity characteristics as well as allow a wide range of adjustment of the vertical angles between adjacent enclosures and the overall vertical inclination of each column of enclosures This means that arrays can easily be optimised to suit the coverage requirements of any situation Sound radiating from adjacent cabinets will successfully blend over a range of included angles creating a coherent point source image and this results in the ability to tailor both the overall coverage and the SPL at a given distance The concept of arraying a point source loudspeaker system is to create part of the surface of a sphere A small part of a large sphere will form a high directivity long throw system with a high SPL at a distance whereas a large part of a small sphere will be of lower directivity producing less SPL at a distance but having a wider angle of coverage This approach leads to the creation of a virtual point source of sound behind the array There are some simple rules to follow to help achieve this goal e Obtain a smooth even curve in the horizontal plane e Use a similar amount of tilt on each column e Ensure that the bottom corners of each column are in line with each other sy Virtual point Soures Turbosound TA 880 user manual Page 16 user manual TA 880 GIGMATE ACOUSTIC SIMU
