Oh! Btw, mount your ceiling M3OW to ceiling tweeters in towards middle of room. Woofers to walls.
If I use FMBs I was thinking that you'd want to aim them ports pointing toward the ceiling ... which would put them the other way ... hmmmm ... this will be an experiment.
Ahhh, I see. In that case I would say you’re fine. Was thinking you were mounting sideways.
Wont those stick down 13” or so? If you have the height I guess all good.
