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

Chadnliz, your room is not small. In fact, your room dimensions are excellent. My previous listening room was 12.5' x 20' x 8' ceiling. With only 1 set of windows behind the speakers (on short wall), beamed ceiling, wormwood paneling on all walls, thick carpet pad and berber w to w carpet, 3 load bearing outside facing walls, the acoustics were excellent.

In fact, I had a reviewer/columnist over to the house just prior to moving and he said good luck trying to find another room like that one.

The only things I did was replace the leather furniture in favor of overstuffed cloth, installed recessed lighting on a dimmer, removed all tables, and floor and table lamps, etc. to lessen in-room reflections.

My suggestion would be to ensure your speaker placement is optimal within the room as this should have a profoundly better impact than room treatments.

Once you're completely satisfied with speaker placement, then address the acoustic treatments, if you think that is still warranted.

No problem, Ausjoe! It took me awhile to figure out Agon's mark-up tags...just click on the link below the "Your response" box.

I haven't built any panels. I'm using a type of foam, 4" thick, with a pyramid structure that is used in studios. I've covered my back wall, to prevent unwanted rear reflections. My listening couch [also very absorbent] sits right against the back wall. I am listening "nearfield".

I've used loctite power grap, 3m 77 might do the job. Myself I would build a wooden frame around your panel, very easy to do depending on your disability you might ask a friend to help. This will make it much easier to Mount and to put a cover on. But a word of caution breathing in fiberglass is not a good thing. You"MUST" put the batting around the whole panel, then the cover. Burlap makes a very good cover but if your cotten is a nice open weave( if you can blow through it very easy) it should do the trick. I made my cover like a pillow case and then sliped it over then either sew it closed, staple 0r use brass tacks.. Good Luck.
