Dave Thanks. The rear absorption panels were a lot of work to get the look I was after.
I will do some more listening this morning with the diffusers in different positions to see what happens.
Dave, Keep in mind that my room is very small so what has been very beneficial for me might not be so great for other situations. For the me the rear wall of the room covered with absorption was the best thing I did. The sound comes at you from the front only, no bounce off the rear wall, which in my case is only 4 feet from my head. I really think the room needs more bass traps.
I was also thinking about placing corner treatments at the wall-ceiling tri-corner points.
Gotcha. That was what I was talking about with the listening position comment. A close rear wall demands absorption.
Upper corner treatment is one of the most important things that you can do in a small room. My listening room is 14'4" x 20' x 8'. Not particularly small or large. Here is a picture of the corner traps that I threw up when we moved in so we could enjoy the music:
The room will get a total remodel after I finish the kitchen from hell
... Anyway, these are 4' wide at the top and 4' long with a mouth at the bottom that is 1' wide. The picture really distorts the width and makes it look narrower. Behind the trapezoid are 3 different tuned traps and a fairly dense fill of fiberglass. My little R/C helicopter dude (Krash Killgore) uses it as a hanger. I have these smaller ones in the upper corners of the room in the rear:
I wish the doorway wasn't there - these would have been bigger, but they do a credible job even as small as they are.
A good thig to try is a small absorbent "L" shape or flat panel angled to form a triangle at the first reflection point at the ceiling/wall intersetion between your position and the speakers. These work well, too.
Dave
