Hey
@Loren Camply, I have a thought that would keep everything on the same space, but gives you a little wiggle room.
Could you scooch the left speaker over a few more inches to the left? Like even with the banister. Slide everything to the left as far as you can, then swap the right speaker with the subwoofer. Or move the sub beside the left speaker and scoot the tv to the right?
One issue I see could be that it puts your right speaker too much in the corner. That's why I'm asking if you can slide everything to the left. It's not much, but gives you a couple more options for sub placement while staying in the same space.
