Well I made a larger one, so if anyone wants to pick up my old one heres your chance. It fits a 15" sub and has an internal volume of 1.9cuft. It has about $220 in material in it and about 15 hours of build time. I'm asking $225, plus shipping. It weighs about 30lbs or so. Its kinda large, so if your in the CT area it might be easier to just come pick it up.

My webpage has all the build pics, if you need them.
