The soundbar must be positioned in a way that the speakers grille faces the room and not the wall. It should also not be positioned behind the TV. Make sure there is no wireless equipment positioned near the soundbar to mitigate any wireless interference.

How far below your TV should your soundbar be?

The Distance Between the TV and Soundbar There should be a gap of between 10 and 15 cm (4 and 6 inches) between your TV and soundbar. The distance is ideal to allow easy access to connectivity and controls.

Should sound bar be in front or behind TV?

You can do this, but it is not ideal. Putting a soundbar behind the TV will interfere with reduce the sound quality by obstructing the sound waves. Soundbars are designed to be positioned just under your TV, and there shouldnt be anything directly in front of the soundbar.
