I was debating doing a project of some sort over he Thanksgiving holiday but m original plan of NoRez for my mains, center got nixed by the budgetary committee. So while trying to think of more affordable projects I started thinking about acoustic treatments. I have no experience with them but have heard glowing story after story so it got me to thinking. My system is in the dual purpose living room, theater room. Ok, theater room in my head at least, lol. Therefore WAF has to be very, very high. Along the lines of" Wow, Honey, I am so glad you did that because the room looks so much better now" type of high. Also the only, and I repeat only place I can put them is on the main wall. The main wall has no corners, the room is a great room design that is kind of an upside U-shape with the main wall being the only wall I could lay claim to. It is 109" wide and opens on one side to the main entrance and stairway and on the other side the room is open to the dining area and the wall wraps around to the kitchen. If you are staring at the TV the kitchen is on the left.
Here is a picture to give a better idea of what I am talking about.

Yes, I know the TV is not at optimal height, I am in negotiations to lower it but I can only get a max of 6" lower as my wife likes to watch it from the dining room table when she is working on her laptop there. But, that also gives me an opportunity. What I was thinking of was building three 24" x 24" panels out of OC703 and then wrapping them in a nice fabric fabric that matches the color scheme of the living room, maybe doing two of one color and an alternating color on the middle panel.
Anyway, on to the audio question. I have come up with three possible configurations for the panels and was wondering if any of you kind people with experience with treatments can tell me of the possible benefits/drawbacks to any of them.
1) I place three panels in a diamond shape tip to tip with the center panel directly centered behind the center channel. The center panel can either be a 2" thick or 4" thick panel as I would have the material for either.
2) I place the three panels spaced out over the wall with one panel behind each RS450 and the RSC200. They would not be directly centered behind the RS450's as the speakers are pushed out to the far sides of the wall for a better sound stage. This is what I have seen most frequently but I believe will have the lowest WAF so is the least favorite option for me.
3) I build three 2" thick panels, place two directly up against the wall tip to tip again in a diamond shape and the third panel over the other two in the center, either as a square or diamond. This would give a thicker center section, but would cover less of the overall wall. This may look cool but since it covers less overall area and would be bunched up may not be as visually appealing nor as effective as the first option.
For reference, the "room" is approximately 20 feet wide (not including the dining area, etc) and 15 feet deep. The main listening position is directly across from the TV on a sofa 1 foot out from the wall. The side walls for first reflection points aren't treatable as one is a counter at the kitchen and the other is a built in cabinet(bar)/bookcase. The back right corner has a diagonal fireplace that eats up space and one corner is flush to the cabinet/bookcase. The system consists of the aforementioned RS450's, RSC200 across the front. Subs are near field as end tables on either side of the couch. I am using Audyssey for room correction and it does help some but if I can do an acoustic treatment that would be of actual physical assistance to the room instead of it being all electronic all the better.
Ok, sorry the long winded post. We were going over acoustic waves in physics today and I kept thinking about this. What do you all think?
