Sure, i placed acoustic pannels on the wall directly behind my speakers. I also placed some on the ceiling above and on the walls to the side. On the walls to the side I placed them at the point where the sound would reflect at an equal angle to reach my ears, which was approx half way between the speakers and my listening point. I also placed a thick heavy rug infront of the speakers. Behind my lsitening point, on the wall, I added some book shelves to try and randomly disperse the refleted sound.
I did a lot of research on the subject that all suggested that behind the speakers and to the sides, absorbtion is key, and behind the listener its all about despersing th reflections in lots of different directions.
All the foam pannels were bought for a cost of about £150 and they are held on the wall by little velcro circles with double sided tap on the back.
I am curious to learn as much as possible about room treatment son maybe if anyone has any thoughts they would like to share?
