To frame or not to frame (OC 703)...

I just got my 2" OC 703 in the other day. It's currently sitting in my entry way, waiting to be used. I also have 15 yards of 56" wide burlap to cover it all. I have a total of 12 pcs. of OC 703.

For bass traps, I'm going to double up on the rigid to make 4". I'm making two of those and they are going in each corner of the front of my room. I say front because that's where my mixing station is. I don't plan on framing them. Only wrapping them in burlap and leaning them in the corners. Is this a good idea? I'm also not sure how I will wrap them all the way around...? Suggestions?

For broadbands, I am torn. Do I frame them or not? If I don't, how do I hang them? Does anyone have any exact measurements on how they cut the wood for the frame so I don't screw up? :) I calculated 50" for the sides and 22" for the top and bottom. By my measurements, this would frame a pc of 703 well.
 
Why not frame them? It'll help with the structural integrity. And will look better. Not to mention you can hang them using the frame.
Sonically speaking, I suppose a non-framed piece of 703 would be a teeny bit better since there would be more 703 surface area to the air. And no frame to reflect anything.
 
through my experience with frames, they add more weight, and you need to make a very strong frame for them to work. Right now I wish I framed some and left some without a frame. If you check out the "soundproofing" thread, pandamonk left a nice picture of a frame that has the sides open for more absorbtion, check it out!
 
I like to frame them if for no other reason, it lets me put on edge details like a radius or bevel and also lets me really stretch the cloth nice and tight for good crisp looking edges.

Bore some holes in the sides of the frames to allow some more exposure if you want.

I decided to go with the framing yesterday. I got all the wood, etc. I finished all 10 frames yesterday and even covered one of the bass traps. So, I have one bass trap done. I have another bass trap left to do and then I have all the broadband's to do. That will take a little while on Saturday.
 
Just pretend it's Christmas, and wrap them like presents. I was too lazy to frame all of them:

I used sewed velcro to keep the fabric tight, and then used the 3M wall mount velcro to mount them on the walls. Works very well. Haven't posted pictures of them hung yet, though (The frameless ones are near the bottom).
 
I just built some for the first time. I made frames but not like any pictured here. I used 1x2 stock configured to sit flush onto the BACK surface of the fiberglass. I used construction adhesive to adhere the fiberglass to the wood. This leaves the side surfaces of the fiberglass open, and is also a lot more lightweight than using thicker stock covering the sides. I used small steel angle braces to strengthen the corners, and also attached lengths of 1x2 as cross braces at a couple of points midway along the length of the panel, which makes the frame overall more rigid.

The fiberglass can pull away pretty easily from the wood with only the construction adhesive to hold it, but I finished the panels by covering them with fabric (using the back edge of the frame to staple to), which makes for a very sturdy final construction. The adhesive is basically just to let you carefully move the panel around until you get the fabric attached. Having the frame now securely in-place, these panels can be hung just like the heavier types, but are light enough that just a couple of picture hooks are strong enough to hold them up.

I don't have any photos yet since I don't own a camera, but if there's any interest I could borrow one to get something posted. A picture would be better than my written description.
 
I framed mine using L-brackets. The only one I *didn't* frame is sitting above the mix position...if it falls you don't want to get hit in the head with one of those things.........
 
today i jsut ripped down all of my treatment and started over. I decided to frame all of my 703. I am glad i did this because now i have a floor to ceiling bass trap in the corners that is sturdy!
 
My friend Bob Sakamano was once framed. He went down at the Beekman. He tried to lamb but they cheesed him.
 
Thanks for that, Rami.

On a side note to the attempted thread hijacking, I finished my clouds about two hours ago. I'm going to let the fabric glue that I used sit for a couple of days. All the other panels are complete, though. The only thing I don't like is how the burlap smells.... :eek:
 
Here are a few pictures. With the exception of the clouds that are drying, this is all of it at my mixing area. There are also 2 more broadbands on the back wall.

Any other suggestions for treatment or is this good? The only other treatment that I can think of is on the window and on either side of the window. I'm going to do that in the next month or so when I get my monitors (Mackie HR824's).
 
I could be very wrong, but it seems like the monitor reflections off of the angled walls could cause problems. You're corner traps are good though!

I was thinking the same thing, actually. However, like you, I'm not sure.

I also reasoned to myself that maybe because of the angle of the walls, the reflections would bounce off into my clouds that I'm going to put up and I wouldn't have any problems. :D
 
You'll definately need some clouds. I'd still put some on the angled walls.

Yeah, I've already got clouds...they're just not pictured.
