How far your TV sticks out from the wall is also a factor.
If the TV is extremely close to (or flush on) the wall the sonos bar can be closer to the TV (i.e. higher up). If with your TV-mount the TV sticks out 5-7" from the wall you'll need to mount the sonos lower (to allow room for the up-firing speakers sound to not be blocked by the TV).
