Are they all made of the same material? I dont have much money, these looks like a cost efficient deal. Great reviews! thanks

Search Super Chunk or OC703 traps. I bought some for about $100 USD and cut them into 17x17x24" triangles (you'll get 9 per 2" sheet of OC703) and then covered them with speaker cloth from Joanne's Fabric for about $20.00.

Amazing difference in the sound!

Thanks for moving this to the public forum. You already got the right answer, but I can add a bit more: That foam is not acoustic foam, and the data they show is fraudulent. The data shows it as being very similar to an Auralex LENRD foam corner, which itself is not as good as more standard materials such as rigid fiberglass in a 2x4 foot size. But when I measured that brand of corner foam in a lab it absorbed far less than claimed, as you can see in the graph below. (SOURCE)

Wow, how's that for free quantitative advice?? Amazing resources here. Thanks Ethan.

As someone who has 703 installed -- +1 on the superchunk method. Easy and cheap relative to other methods.

For the price of that pre-made one - I'll cut up the OC703 and wrap it with GOM 5 times over.

Let me know where you live and I'll ship it to you.

BTW the superchunk OC703 traps are "corner wedge style". Check it out - and there's a video: http://www.avsforum.com/avs-vb/showthread.php?t=700442

All you need is a stapler and a handsaw or a long knife.

None of those are going to get even close to what the superchunks would get you to. You need ping Bpape or check out some his threads.

What about? What about? What about? All of the "what about's" can go on forever. Chat, talk to, email Bpape, or Ethan and get real information and products that actually work.
