How I built MY bass traps...

[acdctom92]

Thanks to everyone for the help during this! I built 6 Traps (so far) and I couldn't be happier with them!

Here are the materials for 2 corner traps.


One frame put together, the other being assembled.


Both frames put together.


Chicken Wire.


Stuffed with R-30.


Wrapped with Fabric, 2 Corner Traps Finished.


Materials for 2x4 panels.

[acdctom92]

All wood cut for panels.


All panels built!


Fiberglass in one.


2 panels wrapped.


Method I used to hang them.


Pannels and corner traps hung!!!

Sweet. What did you use to fasten the fabric? I'd suggest stapling the fabric a little tighter and folding the loose ends over the back. It helps to keep a cleaner appearance. Welcome to the R-30 club!!!

[acdctom92]

Thanks, I stapled it to the frame. May need to redo some like you said. But the R-30 works fantastic! It's like a no-brainer, it's cheap, and incredibly useful.

Great job sir!!!

Great job!
One suggestion is to use plenty of cable ties to hang to fixings on the wall to keep the traps suspended from the wall a little padding.

This is my first post in gearslutz, after reading the forums for a while
I was gonna build some bass traps this weekend, almost exactly the same way, except I didn't even plan to use chickenwire, but just use burlap and staple it really tight.
On your 2x4 panels, do you have enough strength in the middle, or should I maybe add 1 or 2 boards for additional support (so the 4' boards don't get pulled to the inside too much) ?

I didn't use chicken wire on mine. The only one that sagged was the one I hung horizontally. It was more from the placement of the screws and wire than from the frame. It's such a negligible sag that I didn't bother fixing it. acdctom92: how did the chicken wire look under the fabric? Did it show through?

Thanks everyone! I also forgot to add this whole project cost me roughly 175$. I had originally planned to buy the GIK room kit, but I wouldn't have been able to get that for another 4 months due to budget limits, so I had to go the DIY route.

You dont NEED wood in the middle to support it. The wood I used was actually quite strong, and I don't the fabric would actuallly cause the wood to bend in noticeably.

Some parts of the chicken wire(the parts that were originally sticking out of the frame where I tied both ends of the wire together) stuck out. The fabric did it's best to pull it into the trap, but it's still sticking out very mildly.

How tight did you stuff the fiberglass? I mean, did you just push it in until the frame was full or really pack it down?

To you gurus, how would loose cellulose insulation work in a frame like this? It's cheap and easier on the lungs (and environment, I suppose) Any reason not to build frames to fit floor to ceiling with a 2' front, line them with cheap fabric, and shovel them full?

If you use rigid rockwool you dont have to worry about chicken wire or extra supports. Just sandwich it in there and you're good to go. I used 100kg/m3-so easy.

If the frame is the right size, the sheet should plop right in and the tight upholstery would vertically compress it.

As for cellulose, I dunno... check the Bob Gold's page for that info. Probably the Ultratouch stuff would be better. The fiberglass isn't too bad, especially with the Pink brand. I have bad allergies and have more breathing trouble from a dusty house than a cramped studio filled with fiberglass.

Thanks, but the OP has triangle frames filled with R-30. I just wondered if the cellulose would be as good.

Ah, yeah for the triangle frames, I think we both did the same thing... jam 2 sheets of R-30 in until it fit!!

My thought after reading the gas-transmission thread is that fluffier is better in the filled corner traps. Does that sound right?

Yes it is right.

Thanks.

I'm in the process of building a new booth, and I am really liking those corner trap. I am actually thinking about building them into the corners as I construct the booth...

Thanks! They were SUPER cheap and SUPER easy. Need any tips you know who to ask!
