The thing there is that showing you our work would not really necessarily help fix your design issue. Theres lots of people who can build a box and have absolutely no idea how to design one. Id suggest listing what kind of equipment you plan on using, the tuning (or what effect) you would like, the vehicle it'll be for, maybe even performance goals, and then a designer on here mayvtakw you seriously. Also, did you check out the Enclosure Design section of the forum? Give it a read, it quickly becomes apparent who the designers are. Good luck and happy reading!
