It is great to hear your experience. I was thinking with the more directional Soundlab that sidewall reflections were not as much of an issue.
I thought of adding panels, below is my room
Behind my panels are cabinets, shelves, and a fireplace, all that should diffuse the sound.
large monitor between the panels
Ceiling is vaulted, so I shouldn’t have to worry about anything there.
Floor, I have a large soft ottoman that would absorb everything.
One side wall is essentially all glass with a great view, I have some larger plants in front of the glass.
Behind me is open then leads into kitchen.
Other sidewall, there is a loveseat, and a hard wall, possibly add a panel above the loveseat.
