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?

The perforated acoustic panels are made of good material and look good. This is will make your project attractive and these panels are exported from countries like Australia, Singapore and the UK.

By installing the perforated acoustic panels at the right place they will work at their best.
