So we’ve got a bit of a weird setup, which is one big living room / dining room / kitchen area, which is all windows on two sides. We have the TV mounted on a column in the corner of the two window-walls, with the Arc Ultra right under it (both facing diagonally inwards). The couch, however, is facing east-west. Picture below, with the primary listener (i.e. moi) highlighted in green. TV/Arc circled in red:

Struggling with where to put the Era 300s. Options:
- Doing A/B, C/F, or D/E would place them aligned with walls and couch, but diagonal to Arc
- Doing B/C would somewhat mimic the angle of the Arc, but misaligned with the room
- In either case, which direction would we face them?
- Or crazy thought -- put the Arc on the window sill at X displacing it from the TV (which must stay on the column in the corner)?
Suggestions and rationale would be greatly appreciated. Thank you!
