The placement of Atmos speakers largely depends on the specific type of speakers you're using and the layout of your room. If you're using upward-firing, Atmos-enabled speakers or soundbars, these are generally placed at ear level, such as on TV stands or wall-mounted at the same height. They are designed to bounce sound off the ceiling to create an overhead audio effect. On the other hand, if you're installing dedicated overhead speakers for a more authentic Atmos experience, these are mounted in the ceiling. This configuration allows sound to be directly emitted from above, increasing the immersive quality of the audio. So, whether Atmos speakers are "better" on the ceiling or the wall is context-dependent. Ceiling-mounted speakers may offer superior immersion but require a more complex installation. Conversely, Atmos-enabled speakers or soundbars offer a more straightforward setup but may not achieve the same level of overhead audio realism.
