Okay, i learned so much these past weeks (months).

Here are my last REW.

I have in my room : 4 Corners traps (SCC) made of Isover 26kg/m3 GFR around 15. The front corners are covered with a 100 g/m2 non-woven polypropylene fabric

I've built a front wall made of a 30 cm deep slated box (60CM high X 135 Large),
rockwool around 26 kg/m3 GFR close to 9.

Above there is a 20 CM deep absorber, Rockwool 50Kg/m3 GFR around 13/14. 120 CM High X 135 Large), the fabric is a 70 g/m2 non-woven polypropylene.

I'm still building the first reflections traps. They will be 20 cm deep. 50 kg/m3 GFR around 13/14. One on each side (mirror trick)

The last REW is better (i guess, and so to my ears). Even if the waterfall shows highs looking like a comb shell.

My room is closed to the street. REW looks better late in the evening (night)

I hope First reflections traps will improve something. In fact, i'm thinking about the axial width mode at 120Hz.

The door is located almost in the middle of the lenght of the longest wall. I'm thinking about hooking a trap on the door, in order to kill this 120Hz mode.

I'm thinking about a trap on the backwall, for the first reflections. I don't know if it needs to be 20 CM deeps. It will be hooked above the piano. I don't know if it is smart to do so.


Pictures next.
