In the above illustration, you will find the right place for inserting and installing acoustic panels. Pay attention to the entrance and the location of the table.

Actually, NO! That would be a pretty lousy way of setting up a room:

- There is no bass trapping at the rear of the room = major first order axial modal ringing, probably around 35 Hz., 70 Hz, 140 Hz.
- The speakers are too close to the corners.
- The speakers are not aimed at the mix position
- The mix position is way off-axis from the speakers
- The desk is in the wrong position
- The room is too square, and does not appear to be based on any known good ratio
- The mids and highs are over-treated
- There's insufficient bass trapping overall for such a small room
- There seems to be diffusion on the rear wall, but the room is not large enough to be able to use diffusion
- That room would have a an excessive bass boost below around 150 Hz
- That room would have SBIR problems from both the front and rear walls, and probably also the side walls
- The SBIR dip at the mix position will be around 90 Hz and 150 Hz (I can't be more precise because you didn't give exact dimensions)
- There would be unevenness in the mid range (frequency and phase), around 400-800 Hz, due to the layout and incorrect treatment
- That room would be overly dead but also boomy: too much high absorption, not enough low absorption (typical beginner's mistake)
- The decay times would not be consistent across the spectrum
- The room would not meet ITU BS.1116-3 specifications for a critical listening room
