I am mounting my small bedroom studio and I need some help how to place my speakers and add acoustic treatment on corners and/or other places. As you can see attached, the room is not square. Also, in the right corner maybe a problem to put a corner bass trap because of the window (not a real problem to obstruct partially the window for me). Can you give me your opinion where to put some rectangular bass traps and/or corner bass traps?
Should I use the mirror technic to find the first reflection points? Can you explain me how to do it? Is it one person on the listener position and another one with mirror around the walls until reflect the speakers?
I use 8lb mineral wool which is double that if I converted correctly. You probably need to know exactly which material you're using. You can check out this link to find more details: www.bobgolds.com/AbsorptionCoefficients.htm
Sight unseen, try to get an 8lb density for rock or mineral wool. Regardless, try to make your panels as thick as possible. Aim for 8" thickness whether you use a more or less dense ridgid material. You can layer the pieces together for a greater thickness. Just don't glue them.
