I got a pack of OC703 and ready to do the corner traps like Chas. Now I'm a bit hesistant to leave the OC703 exposed. I know the cloth frame will cover it up after the OC703 is placed in the corner.

But I wonder will the fiberglass fragments easily get loose and be all over the room?
Or is there another material besides OC703 that is 'not itching' that can be use?

Good question....I'd like to hear some thoughts on this as well.

I have had my homemade treatments for about 6 months now and have noticed zero deterioration of the OC705. I highly doubt you will have any trouble with it especially if it is covered. Just be sure to wear a mask when working with it. Even an open fabric which is acoustically transparent will hold any loose fibers in.

Agreed - it shouldn't be an issue. The only time fibers behind a cloth can become loose is if it gets banged on pretty good to the point it embeds in the fabric and then comes loose. This would take several instances of being hit.

If you're concerned anyway, you can get 3lb acoustical cotton that performs very very well but is approx double the price.

The traps look great and the blow by blow photos are really helpful too.

Nice looking traps.

Anyone have a plan for traps that, that can be moved?

I am not sure my wife will go for them being permanent to the wall.

Thanks

Thanks hifi....they've worked well for me.

Anthem, I have seen photos of free-standing DIY corner traps on several forums. If you can't track any down let me know and I'll look around when I have time.

Just to add a note, right now, we're offering a 10% off coupon on Tri Traps. This will be good for probably 2-3 weeks.

Though I'm happy with the way my traps turned out...if I had to do it over again I would probably just buy and stack some Tri-traps from GIK.

The traps were designed around my limited woodworking skills. It's basically a stack of 703 wedges with a cloth covered "grill". I started with a triangular wood base and stacked wedges half way up the wall:

At the halfway point a center support was cut from 2 X 2's. The sides were cut a half inch longer than the fiberglass wedges, and cut at a 45 degree angle to match the face of the wedges:

The stack was continued to the ceiling where I attached another set of 2 X 2's with 45-degree face cuts. Industrial stength velcro was attached to the faces of the 2 X 2's to attach the "grills":

The grills were made from 8-foot fir strips with cross braces top, bottom, and center:

Braced behind with t-braces and L-braces:


Test fit:

The "grills" were sprayed flat black and then covered with speaker cloth from Joanne's Fabrics (not too expensive with a 50% off coupon). The velcro was stapled to the back of the grills and they were placed against the 2 X 2's in the corner that had been faced with velcro. That industrial strength stuff is quite strong!
Those look great! I have been plannng on doing the same myself but with the room I am stuck with for my HT due to wifey, I am limited to what I can do...where my subs and fronts speakers are there is a window to one of the side which woul dlimit the size of the bass trap...any suggestions? Could I make them alot narrower and add some treatment to the front wall?

BTW...If anyone in here has suggestions on good ways to treat the room from hell...please let me know...thanks soooo much!

You should start a new thread for your room and post your pictures there...you will probably get some good feedback from regulars like bpape with suggestions on treatments.
