I see plenty of discussion on front / side walls on here but I'm seeking advice on rear wall treatment.
My living room is only about ~4m across. I use curtains on the large window on to me left, and the right is completely open into the rest of the room. Rear wall... The couch is right up against it meaning my head is only about 10-20cm from the wall and it is practically impossible to move my listening position away from it.
I'm looking for treatment advice. Without any treatment high frequencies sound shrill. Indeed if someone claps in the room you can hear a slight echo, so I started listening with a pillow behind me which was a pain in the rear.
Now I'm looking for something better, I've a 70mm rockwool panel in a 90mm frame (20mm gap to rear wall so the rockwool is not flush) but now I'm struggling with it sounding dead. By that I mean now the echo is gone, but also rather than being engulfed in sound I'm quite clearly hearing the speakers (I think this is what is described as a "dead room"?)
What are the recommendations? Is rockwool going overboard? Do I use thinner rockwool or should I be using a different material? Any advice on what to specifically test for as well? (have REW + miniDSP measurement mic)
