I have color coded the house speakers for determining R and L channels. I’m not sure if it is better to have the imaging in the same direction, or the opposite. If I were to reverse some of them, there would be more intercepting area where you would hear a stereo effect.

The blue lines represent zones, and there will be 12 zones for the upper 2 floors, 38 speakers, plus 2 more zones and 6 more speakers on the lower level. I’m going to need 4 of those 12 channel amps, which do 100w per channel for a total of 4400w (44 speakers total).

The little red rhombuses are the subwoofers, which I also need to assign to zones.

Any input on the layout and channel orientation?
