I am by no means an expert, but I would say the first place to start is a large rug on the floor. The second place may be smaller rugs hung on the wall behind the speakers. After this it probably gets more difficult: bass traps in the corners, or acoustic traps along the side walls?
Room Treaments - Where To Begin...
Hi All: I have read countless comments that the best thing you can do to improve the listening experience is to acoustically treat the room. But where does one gain the expertise to do so? There are so many products/options out there. I have no clue where to begin (or if I even need to do it)... Thanks!
