What if you have 2 410s AND 2 115s?
Diagonals? Same stacks? What about all those Ohms?
With that many 10" speakers, you will want to put duct tape X's over all the 10" speakers (on the grille). That will help to prevent beaming and the crowd near the stage will thank you. I would suggest stacking the 410s and the 15s. Separate the two stacks by the recommended (10 + 15) / 2 inches instead of the usual stack up against each other. (If you have room on the stage.)
