...jumping in on the square room factor
You need trapping in all planes & the center of each wall.
Seems that you have the vertical corners trapped well. Move on to every wall/ceiling juncture you can. It would not be overkill to wrap the whole upper perimeter of the room.
The center of each wall is a primary pressure location for your first order axial modes.
It will take as much of these application as possible. Combined, you can damp these powerful resonances to a good degree.
If you don't address some or all of the wall/ceiling you'll likely always find a "hollow" response at critical freq's.
As integral to the trapping is speaker/ear position. Be patient and keep your standards (meaning don't get fooled by your hard work...make sure the room is true).
You can get there.
