703 in cardboard boxes?

b05q · 18th March 2008

the cardboard wouldn't reflect the waves, especially the lows, would it?

It would not reflect the lows.

I'm also interested in this. I've got a bunch of rockwool on my walls now, but I'm moving to a condo owned by someone else, and don't want to ruin their walls. So I'm considering just packing the stuff into boxes, and leaving it in them. Then, I'll stack the boxes all over the place. Does anybody have any experience with using cardboard boxes with insulation inside, for bass traps? At what frequency might this start to be an absorber?

Is there any nicer-looking or cheap but effective alternative to cardboard?

I think it's a very good idea. A little 3M super 77 adhesive and some fabric would work wonders.

I personally bought some hardware cloth to do similar, but I like the cardboard idea better.

On an unrelated note, I found a nice use for cardboard last year. I needed to bake powdercoated parts at 300F. I ended up making a cardboard "oven" to do it. I just cut a hole for my heat gun and dropped in the parts through the top. I walked around it with an IR thermometer, and it stayed a consistant 350 F inside. I get about a dozen uses for each "oven" before it's crispy, then chuck it.

It is hard to say. You would need to test the room with and without them in cardboard.

I'm rather interesting in this (cardboard) solution too... how about if you would handle it like someone do with wood, cutting out some holes etc. and then make it more nicer by cover it with some nice fabric. Could have the fabric a see-through and paint the cardboard with some colors.

Btw. does anyone know about "cheap" cardboard maker which ships internationally? I got quote from a local cardboard maker and it is about $15 per cardboard if I take 20 cardboards.

sure if you cut it out it would work fine.

I probably need to have the cardboard custom made then.... should I add 2" empty space in the cardboard box? So for 6" rockwool I would use 8" inch wide cardboard box. Maybe even add foam sheet?

i've never seen nor handled OC703 in real life before.

how easy is it to cut?
is it messy when cutting or pretty clean
thanks,

Maybe it would even be better to stick foam onto the cardboard box, thus make sure that the high freq. are trapped also?

I decided to add to this post rather than start a new one. I casually mentioned in another post that I filled a 2'x4'x1.5' cardboard box with uncompressed r-19 and laid it horizontally in the floor up against my wall. I am going to guess that I am trapping bass. I have no idea about the effectiveness or to what frequencies. What a great inexpensive bass trap, though. Go to Kroger and ask for banana boxes (check thoroughly for tarantulas...lol). If you put two box bottoms together down into one top, you should get more than enough volume. Go crazy with a hole saw. Stuff with cheap fluffy fiberglass and cover with fabric. Put them at strategic places around the room. For broadband absorption, glue 1" of 703 to the outside of the box before the fabric goes on.

Viola. Your studio now smells like a produce back room!

thanks,

Rigid Fiberglass is really easy to cut with a serrated knife. (make sure to wear dust mask/glasses) and do it outside if possible to limit the dust. I always wear a hat to keep fibers/dust in the air from getting on my face or in my eyes.
