Benefits of Using Line Array Speaker instead of Point-Source Speaker
Sound Dispersion
Line array systems are the best way to get intelligible sound throughout a sizable venue, and the reason for this is the shape of the dispersed sound. Point-source (non-line-array) speakers project sound in a spherical shape, radiating out in all directions from the speaker.
A line array system projects sound in a shape that is closer to cylindrical. This reduces the amount of sound energy that is projected vertically (to the ceiling and floor). Therefore, increasing efficiency and intelligibility and has the benefits of increasing volume levels before feedback occurs.
Efficiency
Projecting sound more efficiently becomes more necessary as your venue size increases. In a large reverberant room, it is necessary to advance your speaker volume to obtain clear, intelligible audio to the back of the room. But by doing so you end up exciting the reverberant field in the room which causes indistinct audio that is hard to listen to.
With a cylindrical dispersion pattern, the amount of sound energy decreases with distance at a slower rate. That means that as you move away from the speaker, you lose less volume, meaning that you can project sound farther away using less wattage. This is an enormous advantage, allowing more direct sound at lower levels, transmitting clearer audio throughout the venue.

Critical Distance Formula
The critical distance of the source can be determined based on the source length and frequency. If you know the critical distance, it will help you find out how many speaker units you need in your system.
