How i built six 4" bass traps

Hello all.
I decided to go ahead and attempt to build some bass traps for my rehearsal/recording studio.
I am from Philadelphia, PA but have moved to Los Angeles back in April of 2009 and it's very hard to get a decent space out here, you can't just have a studio in your basement, so I share my space with another band. The Space is about 225 square feet a giant rectangle with 12 ft ceiling, the walls and floor are carpet and the ceiling is drywall.

Here is some pics of the process...

Here are the 2 frames done, I used pine wood and the hardware store cut them for me. Pretty easy.

Close up the the frames I used drywall screws to hold the frames together as well as L brackets in the inside of the frame.


Each frame was drilled with 1.5" center holes scattred. There is no real pattern here I just tried to stay away from knots in the wood.

The Fiberglass. I didn't use OC 703 or Rockwool but a material called John's Manville fiberglass. It is identical to OC 703 in every way except alot cheaper. For a bundle of this it cost me 90.00 dollars. Thanks to Viking Insulation in Burbank, CA!

I planed on using FRK facing. So i bought 3m Adhesive spray about 7 dollars at LOWES. I layed the FRK face down on the ground (so the silver facing was on the ground, and layed a 2x4' piece of fiberglass on top of it, and cut the FRK with a kitchen knife. It worked well. Then I layed the FRK on top of the fiberglass to make sure it matched well and sprayed the adhesive and attached the FRK pretty simple, though I suggest do a little at a time if you would like to keep it straight!

And FRK done!

I then layed my 2" FRK face down on the fabric and a 2nd layer (no FRK) on top of it. And placed my frames over the fiberglass and stapled the back. I do reccomend covering fabric over the back as well which I end up doing later.

And.....Done!
I had to make sure the fabric was pretty tight after the 3rd trap I had a good technique of wraping the corners which were a bit tricky at first.
As far as mounting goes i used 2 eye holes screws in the back 24.5" down
and used tie wire (used for rebar). Then i drilled hooks into the wall with anchors. Pretty easy they aren't going anywhere.

Sorry for the bad pics I used my phone to take the pictures.
Go here for better and bigger pics if you would like.

Out of interest, what was your prefered method of dealing with the corners exactly?

Thumbs up

Thanks guys.

For the corners what I did was pulled the fabric tight and made like a tight triangle and stapled that to the back.
Glen. Thank you.
I actually I bought 4 of your GIK 4" traps back in 2008 when I lived in PA. But in April of 2009 we moved to LA our uhaul trailer was stolen and everything was ripped off so i lost them.
