Well I didn't think about it before and ended up posting in the classifieds forum, but I need a ported box built for my L7's. It needs to be 5.0 cu feet (about 2.5 cu feet for each L7) and tuned somewhere around 33-36 hz. The box does not need to be fancy or anything, just has to be built well and last a long time. Now I've read that people have been having trouble shipping boxes to Canada so if there are any Canadian builders please PM me. I'll cover all shipping, thanks!
