room treatment 101, please


I am going to be moving into a new house soon and I have a room that is about 16*14 that I'm going to be using for music and movies.

I've never done ANYTHING to "treat" a room for resonance’s, reflections, etc. I know how to place the sub to minimize boominess, and I'm aware that keeping speakers from back and walls can help with smearing. However, where are the most important areas to put up sound-dampening materials (for mid/hi frequencies, and low bass frequencies). I've heard it is the wall behind the speakers and that wall opposite of the speakers, but people have also said that side wall treatment eliminates smearing of sound.

As for low frequencies, I will have a sectional sofa around the back wall opposite the speakers (and on some of the side wall, too). I think this may help as a "bass trap."

So -- can you start from square one about which walls are the most important to treat/address? I'd like to "fix" those first and my wife will still want things to look good. The room is a family room that can't accommodate big book cases and such all over the place, and the sofa will be backed up against the wall (sorry, but it has to be that way). Much of the rear wall (the one opposite the speakers) is taken up by two large (reflective!) windows. I was thinking some drapes might help here?

Any advice/education would help. I'm at the point where I want to make the best use of my equipment by fixing my room, and not just keep buying better stuff for the same flawed listening area...

Tis will be short but will be the most acurate info you will get trust me my room is a foot bigger than yours it is a dedicated music room. I use a levinson gear and martin logans. I had a sonics speacilist come out to the house here is what you need. You need 8 2ft x 4ft eggcrate or sound board your better off using the eggcrate that they use in studios you can wrap it with grill cloth if you dont like the looks. you need to put 4 peices behind your listening position and four on the left wall or the right pick one not two because it would be to much. you can also buy two more and put them on the ceiling in the center to kill any slap echo. good luck this will work. It should cost around 150 to do this. Here is the guys number who helped me he owns a company in connecticut its called viber sceince 203-483-6113 get it in grey tust me. He will ask you for your room sizes and calculate it over the phone and he will tell you what you need. Just tell him that he just sold some to a guy named Dan with a highend audio system. good luck
