Ok let me clarify. The hall is rectangular so you walk in the bottom end and look up the "length" of the hall and at the other end is the stage (on your left) and beside it (on the right) the dance floor. Stage and dance floor take up all of the back wall. When you are on the stage looking down the length of the hall the dance area is directly beside you on the left, then the bar is basically down the rest of the left wall.
All the seating is directly in front of the small stage.
So, would the speakers be better front of the stage facing the seating or on the dance floor or some other arrangement?
Speakers are Behringer Eurolive B215s with an Allen & Heath Zed 10 FX mixer.
