 Thanks to suggestions from this forum (about one year ago), I’ve been using a long wall set up with a good deal of success. Because of the room setup, I’ve had to position both of my monitors in front of two windows (4’ x 3’ windows). Obviously, when the windows are open, so is the sound and soundstage, but with the windows closed, the sound loses clarity and the soundstage loses focus. I have been searching for acoustic material that won’t suck the life out of the sound but that will cover those glass windows. Drapes do not work well (they seem to over-damp the room). So far I’ve tried ATS panels and echo buster panels, but I keep thinking there must be a better solution. What would you all use in this situation?
Thanks,
RAC

 If you have normal "box" type loudspeakers, most of the sound goes forward rather than back toward the window. In that case a better location for absorption is on the rear wall behind you, and possibly on the ceiling too. I also think you might need to give yourself some time to adjust to the sound of absorption. An open clear sound is generally obtained by reducing the strength of the reflections. What seems too dead at first may seem better and clearer after a few days or weeks.

 Thanks,
I have some extra pannels I can use on the back wall.
The ceiling is 7.5 feet in height; my monitors have ribbon tweaters, so their dispersion is primarily horizontal (rather than vertical). I'm now wondering about the midrange and bass reflections from the ceiling.

Ethan, I think this is good advice.

As a follow up question for the OP What would you think of a large slat plantation shutter for window treatment? These could be opened to various degrees of diffussion for the front wall reflections.
