Hi,\n\nI've been reading several posts here and doing a bit of research for a home theater setup up in our future renovated family room in the basement. I'm struggling to commit to something as there are issues with the angles I'm trying to replicate from the dolby guide. My goal is to figure out a 5.1.4 setup. \nHere are some drawings for reference\n\nFor the first scenario with the couch closer to the back wall, the 5 main speakers seems to work well. The surrounds can be on brackets at the back wall at 110 degrees. We would prefer them to be mounted on the wall, if possible.\n\nHowever as seen with the profile view, the back 2 atmos speakers would be way off the dolby angles. I don't have it noted, but it would be about 70 degrees.\n\nFor the second scenario, with the couch moved closer to the TV, I can get the back 2 atmos speakers at a 55 degree angle. While this scenario can get the minimum angle, I'm not sure if it would be an issue having the atmos speakers just above the ledge at the back of the room.\n\nAnother issue with this setup is the surround speaker on the fireplace side. Now that the couch is moved up, 110 degrees puts the speaker in the absolute corner of the room if mounting on wall bracket. I'm not sure the extent the fireplace would obstruct the sound and its overall impact. Ideally, we would prefer having the speakers mounted on the wall than having them on stands. The fireplace makes things a little tricky.\n\nI'm not sure if I'm thinking too much about the angles and I should just try to get the best sound possible. Is there a configuration that would be preferable or something I haven't thought of? Or should I accept the fact that 2 atmos speakers may be the better option? While I measured the mlp at about 1.2m, I wouldn't be surprised if its 1.1m or 1m when siting or lying down more comfortably.\n\nI've also debated having 2 subwoofers, but unsure if the room warrants it.\n\nAny advice is appreciated. Thanks!
