My listening chair is against the rear wall. This results in relatively strong bass at that position, although the bass a little further into the room towards the speakers is more balanced. Someone advised me to use gypsum board on the rear wall. It works! And if I leave an air gap between the board and the concrete wall it works even better. Better than rock wool.
Would like to know if any of you have experience with gypsum boards. Any information on the acoustic properties of gypsum boards will also be useful - does it absorb specific frequencies, etc. And what is the air gap doing?
Thanks
