Great graphics. Very helpful and quick. I think my backer boxes are somewhere between what you have going on. Front heights are about 5' ahead of the listener plane. Rear heights are about 3 1/2' behind the listener plane. I hope it works. Thoughts? We hosted some friends I previously designed a room for. He is built and into the buying gear stage and is going 11ch ATMOS right away. The envy....

I will probably end up going angled for the front heights and down firing for the rears as they are a little closer to the listener plane. Thoughts?

Good info Nick. Still a go to for all things HT!
