This is my problem child. The opening is now French doors and the baywindow is from ground to ceiling. The projection screen is in the bay window and all gear is under it. I have two couches, one 1’ from the back wall, and the other by the windows on the sidewall. The room has a 10’ ceiling and real bad echo. The bass is boomy and the overall sound is bright. Can you help to treat this room? Thanks in advance.
