|Room Size (LxWxH):||20 x 13 x 7.5|
|Room Comments/Treatments:||The stereo is set up in my family room. It's a sunken room, connected to the living room through french doors. There's wall-to-wall gray shag carpeting on the floor and my listening chair is an overstuffed sofa pulled about 1 foot away from the long wall. The speakers are oriented along the opposite long wall. There are sliding glass doors at the far end of the room, to the right of the right speaker. |
The right speaker is located according to the Cardas golden ratio method for speakers oriented along a short wall. The speaker was then rotated 90 degrees to face the long wall. The left speaker is oriented so as to be symmetrical to the right from the center of the sofa.
When I first arranged the speakers this way, I noticed some upper midrange glare and lyrics were slightly unintelligible. Removing the large glass-framed print which was directly between the speakers helped reduce this slightly, but not entirely. I wound up building two absorber/diffuser panels. They are 2x3 boxes made from 4 cedar planks, with ½ styrofoam in the back and ½ grid metal screening in front. They are lightly stuffed with pink fiberglass insulation and wrapped with $3/yd gray suit material from walmart. I didnt want them absorbing a particular frequency, I just wanted them to be poor reflectors of sound. They are mounted on the wall behind and between the speakers, with a 8 gap between the panels. They seem to work pretty well no glare, no harsh highs, music and lyrics are intelligible and engaging. The panels also look extremely cool. The gray suit material was a good choice.
Pics are from my camera phone, sorry for the bad quality.
