the wall. Then buy mounting brackets that attach the sound bar to the tv mount so it hangs just below the tv with no space. The cables from the tv to the sound bar won’t be seen.
Grommets are a couple of bucks at Home Depot. Mounting brackets for the sound bar are $30-40 at Best Buy or Amazon.
Another advantage of this setup is if you have an articulating mount that turns from side to side the sound bar will move with the tv.
