DIY Room treatments..How Large?????

Hi,
I picked up a sheet of Owens Corning and some low profile batting material for front face of panels to "soften" the face appearance, and some Natural Needled Cotton fabric to wrap panels in, I have 4...2ft X 4ft pieces to work with, I want to tame one wall, as other has a sofa along it and a quilt rack at first reflection point. I also want to place one on ceiling at reflection point and 2 on the back wall.
My room is small, 13X20 and I wanted to know if I place one 2ft X 4ft panel in middle of room on ceiling at reflection point would 4ft across be enough width and 2 ft be enough from front to back?
Also if I cant make a tube trap, could I use more of these behind speakers? or will these be less then ideal?
As far as making tubes it seems both hard to make and also hard to purchase the right suppplies with me being disabled and on a fixed income but I do want to make the best out of what I have.
So in short, will my panel be big enough for ceiling reflection?, I will also use one on live wall to tame it down and have 2 left for back wall. and if I get one more peice, and material could I use 4 more for corners behind tower speakers...as always thanks a bunch guys Regards,
Chad

Hi Chad I'm no expert but I do know another website where they talk about both the materials and issues you asked about; http www.ethanwiner.com/acoustics.html. Also Burlap is mentioned by Jon Risch as being less reflective a covering than cotton. I think thicker is better. Tried to make a link. Hope it works, ha!
Cheers Larry

I've made DIY panels, just got them up this weekend. Have only done limited listening so far. My room is 14x18 with a sloped ceiling. I've got 2 2x6's on the front wall, 3 2x4's on the rear wall, a couple on each side wall, and 2 2x6's hanging from the ceiling. I have to say, I think I needed that many to get the slap echo out of the room! They were easy to build (including wood frames), and easy (but time consuming) to mount. My impression is that a couple 2x4 panels may not be enough - but I'm sure it entirely depends on the room. In mine, I have a 5x8' window that "rings". It is a continuous double glazed window - not broken by any framing at all. Might have to replace it.

Ethan Winer's site is good. I believe that he has designs for making corner traps with panels and/or loose insulation, rather than building tube traps. Check it out.
