Where is the bass trap study???

I remember reading a few months ago a study that an AVS member did on the effect of bass traps in his room. I thought I had bookmarked it, but cannot find it anywhere. It was very well written, in plain English and covered how he put bass traps in the corners of his room and included the corresponding measurements. I could have sworn it was Braidkid, but when I checked his sig, I didn't see the link. Anyone remember this?
