Hello.
I recently purchased some Era 100 speakers to connect to my Sonos Arc.

The room is large, and I use them for both movies and music.
I've read that for the most immersive sound, the best position is B, but that would be detrimental if I'm watching TV or listening to music at the table.
What setup do you recommend to immerse myself in movies and listen to music from across the room?
Thanks in advance.
