How to treat this room?

[smy1]

Hi everyone. I moved into a new apartment and am currently treating my songwriting suite/homestudio room.

The room looks like in the attachment (sorry for the bad drawing ...).

There will be curtains across the windows and the floor is laminate flooring. The listening position is at 38% of the length of the room, with the speakers facing towards the couch/door.

I put large (about 2 meters high) broadband absorbers into corners A, B and C (diagonally across the walls) but I don't know how to treat the corners D and E because:

1) I want to put a couch at the back wall and a diagonal absorber in corner D would take up a lot of space

2) the doorframe is too close to the wall in corner E, to put something diagonal there.

My idea was to put

1 small absorber (1m x 0,65m) left of the listening position
1 small absorber right of the listening position
2 small absorbers above the listening position
1 small carpet under the listening position
2 small absorbers behind the couch onto the wall between D and E
1 small absorber onto the wall to the right of corner E, as close to the corner as possible.

What do you guys think of this?

Any help is appreciated!

Those will help but what would be better is to straddle more panels that are big. How about in the upper corner along all walls where the ceiling and wall meet? All corners pick up bass.
