Minimum acoustic treatment for room-Acoustics Forum-Acoustic Fields Forum

Hi everyone,
I am new to this forum, just joined today.

I bought a pair of Mackie CR8-XBT studio monitors.
They have 8″ Drivers with a Rear bass port of around 2.5″.

Here is the top view of my room:

Since my table is only 2ft in depth, my sitting position in the chair is at a very high angle of around 120degs wrt to the speakers (instead of the ideal equilateral triangle measurement of 60degs).
The speakers are around 3.5ft away from each other and facing straight.
I tried angling the speakers towards my ears, but that tended to cause me ear fatigue much faster (i.e. when the source of sound is directly facing my ears).
I feel like I am sitting too close to the speakers, and the angle of 120degs is too steep.
Unfortunately there is no space to move anything about much unless I buy a new setup/table etc.

So far the arrangement I have shown sorta works the best (as of now).

My Question:
Will I get a big improvement if I put acoustic 2″ foam pads in the wall behind the bass port of each speaker?

Please let me know,
Thanks.
