Don't hate me for saying this but I would think about adding a 3rd unit. The overall spread for each unit is 25-35 inches at 9 to 12 inches in height. For two units I would start at 12 inches with blues at 100% and whites between 60 and 75%. Maybe have someone hold one at that height to see what it looks like.

For two units mount like this:

For three units:
