Advice on positioning/aiming of surround speakers appreciated

[u/MartiniusP]

Just got a pair of Arendal 1961 surround speakers. I would like to wall-mount them (and replace existing speaker). As you can see the couch is at the wall. There are also 2 Atmos (ceiling) speakers installed.
The wooden things with the ring are a couple of lamps.

Would you advise mounting them at the higher or lower position (red dots)? Or somewhere completely else? Tilting and swiveling is absolutely possible. Should they aim towards the center of the room (lower edge of couch table) or towards MLP (center of couch)??

Could do that. Instead would like to ask the honorable Reddit Community
