I am in an 11 by 12 room with 8 foot untreated ceiling. I too use GIK acoustic panels. The speakers are pulled into the room say 3 feet. I have a few feet behind my listening chair. It is a 5 1/2 foot triangular set up. At first I had the speakers slightly wider apart but noticed that seemed to give me a wide stage and depth but there was a hole in the middle. The trick was moving the speakers just two inches closer together. It takes a lot of patience but once you get there you will have the width, depth, and height...and those layers will sound lovely. Albeit in such small spaces one might not get 100 % the I can walk between the instruments with ease effect that Jay Lee and Thomas talks about. As far as too much speaker that someone mentioned--I run two 12' subs in the room along with my Sonusfaber Oly 1s----the bass is well balanced. And finally those that mentioned how the music is recorded are spot on too. Some recordings just do not have the mix to allow for spacious, enveloping sound. Best wishes!
