This has been a great discussion and it makes me think about using M5OW as surround channels. M3OW would be fine in my space, as they are each 8’ or so from the MLP. If I get full integration at 8’ they will be M5OW.

I will take some measurements on the vertical plane and post the graphs here. If in fact there is an integration distance in which all drivers essentially blend evenly off vertical axis I will let you know. I dont believe this works with an M5 but will an M3.

Mojo with low ceilings and closeplacement the M3IC may be fine for you as in Michaeld’s setup. Pretty sure his room is set up properly so I would trust his input.
