we moved our room around last week to try and make better use of space. The speakers now sit infront of a bay, they are out in free space away from the actual bay but inline with the angled wall of the bay. It seems to have had a detrimantal effect on the soundstage, everything now comes from one spot central between the speakers. Im not panicing as i know my setup has sounded better. I would like to try and sort it out without having to put the room back as was because the layout is better and with more space. So i im guessing i need some kind of treatment for the wall of the bay (curtains over windows when listening), but i dont know what i need, damper? diffuser? anything else?
