directional speakers?

[morsey]

hi

i am in the third year of my degree and our final group project is to design a sound reinforcement system for a critical listening environment. for this environment we have chosen the focal point in a shopping cenre in leeds. The walls do have acoustic treatmenst to minimize reverberation yet we tend to install a temporary pa system and we need some highly directional speakers. Does anybody know of any such products?

Line arrays may be what you are looking for. Since they focus sound within the vertical plain of the array, just elevate the array and angle is downward for a focused listening area. You may even be able to focus the array further with a concave layout of the baffles. I know this works for near field listening, but far field may present more problems.
