HiFi room acoustic treatment

Hello,
From Europe alone, native language is not English to me. I pray for understanding.
 
I joined the acoustic treatment of the ceiling and the wall behind the loudspeaker. On the ceiling go Rigips Rigiton 8-15-20 gypsum boards, and above them stone wool.

On the wall behind the speaker goes 15 cm of stone wool, gypsum panel with 8% perforation, and another 5 cm of stone wool.

I am concerned about the final layer of the wall. I would put 2 cm wide strips, with a distance of 2 cm (50% coverage).

However, I can not find a stone wool with the finish in the appropriate color. Can I put a thin microfibre fabric over a stone wool?

well, not sure if anyone here is fluent in Croatian, or if you can buy that book - why not start checking libraries to see if it has been translated, or if something similar is published in Croatian

here are some helpful sites:

only for a rectangular room:

and here is one from Canada (which features the treatments they use in their igloos and snow caves):

The acoustic treatment panel has been designed and tested in acoustics laboratory, so the sound absorption curves for each panel thickness are very predictable. The result is a series of products that can improve the acoustic performance of any public space. Visit here for details: https://www.fabricacousticpanels.com/acoustic-treatment/
By using a thicker fabric panel or by incorporating air gaps between the panel and the ceiling, up to 100% of the noise can be absorbed at a particular frequency.

I treated the walls of my shoppe in Florida, behind the listening position, with a treatment similar to what you're describing.   Don't know what color you're looking for, but: I found that simple burlap, over 2" of rock wool, stapled to the strips of wood, eliminated all the slap echo in the room.    Various(but limited) colors are available:  http://www.joann.com/burlap-fabric/prd23682.html

High nrc perforated acoustic panels for walls and ceilingsPerforated ceiling panels are easy to install, easy to disassemble, and easy to use. Exposing to the grid system creates an attractive ceiling.
