how big is your church? multi speaker arrays using smaller drivers, 4inches say, can work here.....

be ready to use 100volt distribution system......

it is big.....distributed system is the way to go, otherwise sound distribution may not be uniform and you run risk of dead spots.....are you mounting those speakers overhead?

yes sir tony... it will be mounted overhead. one thing am planning to do is to make two of the speakers active... the other two will be on a passive mode and will be connected in parallel with the active one... any recommendations? i believe 1 b500 of sir apex can handle 2 12 inch instrumental speakers right?
