I made something called a porta booth....using eggcrate mattress foam and a collapsible cube drawer.

works great as long as you don't stick your head in the box. the foam does most of the work. speak in front of and at the box.

I only made one reel with this so far, and that was to test it out. great for people who don't have a big budget and still want a decent sound.

I learned how to make it using this article... http://harlanhogan.com/portaboothArticle.shtml stay awesome.
