Hello, I have two 5s and a one sl in our living room. I just ordered a one, to finish off the room. The room is 40’ x 12’ and I am going to put the speakers up high, about 6.5’-7’ up. Which way will I want the 5s positioned, landscape or portrait, I want the volume paired so when I turn the volume up, all the 5s and ones stay the same, without have to adjust each. I don't really care if they are paired in stereo though. I have a one sl and a move each is in its own room. We generally have the same music playing through the whole house. But need the volumes for each at different levels. I want the living room to be blanketed in sound though. It is just for music, not tv. Here is a rough diagram of what the room looks like and where I was thinking of putting everything. The main concern is changing the speakers in this room equally at the same time, and whether the 5s need to be in portrait or landscape and if it matters. The blue object are sofas and chairs. Thanks
