I am building this room and from the dimensions you can see it is quite large with vaulted ceilings so a large volume of space too. My intent is to install a 75” TV on wall A and to have a Sonos Arc soundbar and subwoofer under the TV with Sonos speakers in the opposite corners marked as B and C.
I am worried that the space will be too big for what the system can deliver and also the fact that the rear speakers are not in a 45 degree angle relative to the soundbar underneath the TV.
Any suggestions will be much appreciated as I would not, ideally move away from Sonos.
