I finished the ASC clone bass traps and you can see pictures of what they look like in my room at the bottom of the page. I also took a lot of pictures of the new build process which involved a spiral wrap of twine that helped with the assembly. Amazingly I was able to assemble three by myself in one night. The sonic differences were there, nothing miraculous though as you'll see from the response graph at the bottom (before/after). I plan to run a few more tests and try moving the sub and traps a bit more. The page is intended to help newbies build them so if you have any questions let me know and I'll edit the page post haste. As far as the physics behind it, I believe it simply slows down air movement in the high pressure regions of the room hopefully lowering the standing waves that occur. This proved to be true when I measured a 2db increase in SPL at a 63hz room dip just by adding the traps. Link to room with pictures of trap sitting on top of adire alignment tempest. Link to the Bass trap page only I'm very pleased with the sound now so I won't be building diffusor panels like I thought. My room is getting pretty crazy, any comments welcome as they'll probably be better than the comments I've been getting from my family.
