Re: Endfire sub array under a stage
If the stage is as you say-then what is the point of using directional arrays?
You would get more energy out front if you DON'T use directional arrays.
AND you have to have enough room for the waves for each of the speakers to reach the other in order to work properly.
The whole idea is to have cancellation BEHIND the array-a DISTANCE behind. Right on top of the array there is not going to be much cancellation going on-first because it is in the wrong direction (up and not behind) and second because the distance to the stage is not far enough away from the subs to really do anything.
There are lots of variables and often try to do things just because they can and it makes them "seem cool", NOT because it actually works or has any real benefit.
