My room treatment consists of the possible furnishings in the room. I have tall bookshelves in the corners to right and left behind speakers with DVDs filling most of them. The shelve are somewhat custom so they ar about 7' 6" tall, and thin in depth. They start right from the corners.
The back wall is a large window, with half open floor/ceiling draps, Then a low open design leather chair in between, with the amp behind the chair. My Magnepan 3.6 are about 4 ft ave from back wall and near-side edge is 2 ft from side walls with a larger than usual opening between, with tweets on inside edges. I am very satisfied with this position, and would say it is the final location of the speakers in space.
That's it. The equipment is at side of listening part of area, which is about middle of total front back space.
A loveseat on right, the plasma and stand on left. TTs behind on left wall, with rack closer into room to reach from seated position.
Good sounding, and little bass into walls, the bass seems to be channeled right to the listening position, with toe in of about 30 degrees. (eyeball guess-timate)
Perfect for low level 65dB to 80dB listening in apt.
Behind listening more shelves with stuff. The LPs are not stored in listening area.
I cannot stand the bits and pieces of artificial 'room treatments' so I would never allow them to be in my space. If it is not a usable functional item of normal furnishing, it ain't gonna be in my space.
The only thing I have thought about is some sort of wall hangings, more to insulate ajoining apt wall than to improve my experience.
