It’s hard for me to tell from the angles but it looks like the locations aren’t where I would like em. I’d fill the holes with new Sheetrock and put the speakers where they should go. But MAYBE sits the camera angle...
NOW, based on the numbers, it seems they’re closer to where they might work. Better pics?(or better help desk? Lol)
You’ll want definitely have them over the seats. The actual height will likely be determined my the couch height. The spec is for “mains tweeter height X 1.25) but I think somewhere around H1x1.55 is ok. Especially if you have multiple listeners, you’ll want to have the tweeters NOT blocked by people’s heads. Here’s a little visual aid.
That’s probably a good height with some angle down and forward for a 7.2 ch system but just too high for Atmos.
GUARANTEED they just wanted something for out of the way.
the aimable tweeters are pretty much useless, especially if they’re 14’ off the ground. The 15deg baffle will be much more useful, and one of the reasons I bought them. Also Joe Rodgers entertained all of my questions from super geometric diagrams I made to BS’ing about my LR and moving to California. The guy is great.
Also. The 4400 will definitely run your 7.2ch system in the meantime. BUT it won’t use PLIIx anymore. I don’t like PLIIx so I don’t care, but it might be a problem for you. Dsu is spectacular but your layout is not Atmos so I don’t have any predictions on what it would do. Just don’t upmix I guess.
