I am using a pair of the new Phase 4 diffusers and
4 echo busters that hang on the wall.
Good luck,

Heeengky, Absorbers and diffusers are not the same thing. They are as there names imply. Typically, absorbers should be placed at first points of reflection. Side and back walls are the rule of thumb (even ceiling). Diffusers are usually behind the listening position and deflect the sound waves in various ways. However, I suggest absorbers behind the listening position if very close to the back wall. The idea is to cancel reflections and modes but not over-deaden the room. There's a ton of information available on how to figure placement with mirrors, lights, test cd's, electronics, mics, and your own trusty ears so I won't go into details here. Don't overlook the corners where bass modes accumilate and are potentially the most harmful to your sound. I'd even suggest you start there. ASC and Echo-Busters are very effective and attractive. You can find them here on the Agon occaisionally at good prices, but they are $$$ new. There are many ways to treat your room that are not exspensive. Do the research and learn how sound waves interact with your listening room before you spend any $$$. The education is worth it. Hope this helps and good luck, Dave
