impact of room treatment


I am curious what benefits have been seen through basic room treatments. I was thinking of starting with panels in the front and back. I am looking for seperation of sound, depth-wise...in the midrange. What component of the system would contribute most to this aspect?

Ready Acoustics have very effective and good looking panels at a reasonable price and give free advice. My wife actually told me to buy some more of them; enough said! You will not believe the difference good room treatment will make.
I have several ATS Acoustic panels in my room. The company has been great so far for me with quick shipping and quality build. One of my panels is a custom order which the web site says may take a bit longer. This custom panel arrived as quickly as the other panels.
My room (11x13) is furnished with only two chairs for listening and a set of shelves holding cds on one side. There is nothing else to remove/absorb/diffuse reflected sound.
First and most notable difference was a reduction of harshness with the addition of 4 inch thick panels at first reflection point. It cleared up the imaging and brought the soundstage into focus.
There is a 4 inch thick panel directly behind the listening position and I also use Aurelex bass traps in two of the corners which seemed to help tighten up the bass.
With these treatments I can turn the volume up much further than before without overloading the room.
