Pics of room - where to start with acoustics

**cburbs** · **04-25-08, 07:55 PM**

Will 8# MW work for the Panels since this is what I am starting with - This is my plan for the front.
Panel left/right of screen and one below behind center channel & left/right as 1st reflection points.

back will be like pic attatched.

If you're DIY'ing, do teh entire front wall. 8lb will be fine for this and the back wall. For the sides, I'd personally prefer something less dense since you're going to have some reflections with pretty shallow angles of incidence dnt the denser material can allow it to skip off sometimes.

For the front walls by the two main speakers - is a acoustic panel behind each speaker better or my other thought for now is make two panels and stack them on top of each other and angle them in the corner.

On the building process is there a better way to build them - one without a backing and one with.

How much room do you have on either side of the screen to the side walls?

**cburbs** · **04-26-08, 09:54 AM**

It is exactly 11 1/2" from the outside of my screen to the side walls. So if I made panels the MW would be 9" wide if I used 3/4" wide wood as this gives me 1/2" of space on each side of the panel - similiar to the diagram of the front wall above. I cut out a piece of cardboard that was 10 1/2" wide by 4' tall. Now if I use a acoustic panel on the front wall and my speaker has a high port and low port on the back side do I want to lower the panel as low as the lowest port on that speaker?

What type of fabric do most people use if they buy locally? Burlap
Is there anything else that is usable?

With the wood frame what is the best size/type of wood to use?

I used burlap for my corner bass traps not counting the GIK ones stacked over those in the front of my room to cover the front wall. If your considering the burlap because it is cheaper or more convieninet to find, I don't think that you would regret using it. My side relection panels are also burlap. If it is appearance is very critical GOM might be the route you would like to go. The weave is slightly different also. Burlap up close looks almost like it is covered in lint.

Fortunitly mine are in a very dark room and they are black (dark color also works) and nobody would be able to tell. You want to use strong wood that is light and easy to work with. For the wood, maybe someone would comment on the different variations in the different price ranges but it is not set in stone what is best.

You can also use Muslin. It's inexpensive, dyable, and relatively smooth in relation to burlap.

Here is a link some examples of muslin. http://tinyurl.com/3nrqu3

Ref Post #28 for two different style builds - is there a preference on how to build the back area of the panels?

**cburbs** · **05-11-08, 07:33 PM**

Here are some shots of my first panel

**ecir38** · **05-11-08, 07:44 PM**

Looks great. Where did you get that fabric?

**cburbs** · **05-11-08, 08:10 PM**

Just some cheaper fabric I found at JoAnne Fabrics. $3.99 a yard though I did get some of it on sale. I didn't buy it all at once as I wasn't sure on how it was going to stretch over the wood.

It says Black Scroll 3680899

Looks great Chad....

**bpape** · **05-12-08, 11:37 AM**

I like that Fabric. Do you remember what it's called by any chance?

Bryan

**cburbs** · **05-12-08, 12:06 PM**

I can look at my receipt. I basically looked over in a section where they had items seperated by colors and looked at the black cloth with designs on it. I didn't want anything too busy that showed it and this is but it doesn't show it like the rest of them. Some had skulls, circles but where big and stood out - more black on white.

**cburbs** · **05-15-08, 05:46 PM**

Ok so I think I am going to change one in the back on the left...any thoughts

**Prof.** · **05-15-08, 06:30 PM**

I prefer the first way you showed it..keeping all the panels vertical..

I agree with the Prof. ... if you want to rotate it because you want to cover more of the wall, you can make another to fit in the space you have left

**cburbs** · **05-15-08, 08:09 PM**

Right now I only have 5 big panels so if I don't rotate it do I put it where the poster was or dead center on that back wall.

I'll say dead center ...

Later when you build the other you can move it.
