Minimum acoustic treatment for room
Posts: 1

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:…..s2HUQSN787

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?
Like this: colid=2UX0V3WBZOM7S

Please let me know,

You must develop a sonic strategy for your room. Using tactics (a few pieces of foam here or there) is not a strategy. Without a sonic goal to achieve, you are just guessing and wasting time and money. Decide on how you want your room to sound and then go after each issue in a step by step procedure. The first set of issues you must address are the low frequencies within any small room.

After watching many of the YouTube videos , I finally asked a very similar question. And after that I started watching the old videos , I went down from a 8 inch woofer to a 5.25 and what a difference it made in that room.
Sometimes bigger isn’t always better.

Less is best when it comes to low frequency pressure. With less energy, you get more definition and separation. All energy input into a room creates error.
