I am planning the install of 2 acoustimass 15 series ii in my 7.2.2 system in home theatre (12x16x10).
I am thinking of using 1 system for left channel and other for right with each having their own center and ceiling mounted cube array. Center speakers using center channel on receiver (total of 10 cubes).
I have a Pioneer VSX 1130 reciever which supports Dolby Atmos 7.1.2 with dual preout sub connections.
It looks like this should be fine, but I would recommend checking out these configuration diagrams from the Pioneer site HERE. I found a lot of good information on the different configurations on page 22.
