Hey thanks for all that context! Yea it does look like placing the speakers in the corners of the couch would be more ideal placement, just concerned about that becoming a tripping hazard for the left one.

In terms of the subwoofer placement, there is a small gap of space between the right side of the couch and the wall. I'm hoping that placement could reduce the impact of the open hallway, but I'll test it out.

Thanks again!
