The budget is somewhat flexible as long as all parties involved can be convinced of the value.
The coverage area is the field and the stands. I think I have the stands figured out with your everyday BGM/FGM 70v boxes.
First they have to determine what "value" really means.
I have done baseball fields just fine for a couple of thousand dollars. The last one was around 40K.
Of course the last one was much louder-had nice solid bass etc.
Doing a simple baseball field in EASE should be pretty quick. BUT FIRST you have to decide what speakers you want to model-and of course this depends on the budget.
You say that subs "are not going to happen" but you also say that the budget can anything as long as you can convince the owners.
This is confusing to me-maybe you can clarify a bit.
As with ANY project-FIRST you have to define the parameters to work within-price-what is expected etc.
REAL numbers-price-SPL at what distance-freq response. Those are the absolute MINIMUM numbers. We won't even start to talk about things like STI.
Without that it is simply a waste of time.
Let's say the wife wants a new car.
Do you go straight to the high end sports car dealer? What if she wants a minivan to haul the baseball team around in and you only make minimum wage.
DEFINING the goals and expectations are paramount to getting useable answers.
Just throwing up some "full range speakers" is NOT the way to design a sound system. Yes it will make noise-but how WELL will it make that noise?
