I'm going to be building the enclosure for an Adire kit81 within the next week but I have questions. First, I need to know how much i need to add to the required dimensions inorder to get the desired panel size. Adire says I need the following: 4 14" X 9" pieces 4 9" X 10.5" pieces 4 12.5" X 10.5" pieces 2 7.5" X 10.5" piecs Am I correcting in adding half an inch to each dimension inorder to end up with the correctly sized panel? ex. Mark a 14.5 X 9.5 inch piece of wood and cut it, as about half an inch of wood is removed when using a circular saw. Is that correct? Are speaker boxes just held together by glue? I have some gorilla glue here and eventhought it's suposted to be very strong, I don't really believe that it will hold. Should I use some nails or screws to secure the pieces? Lastly, does anyone mitre their enclosure pieces? I don't think it's necessiary, I was just gonna "butt" the pieces together, fasten and clamp. Only advantage I can see ot mitreing is a better finish, if your using a hardwood for panels, and a larger surface to apply glue too. THanks.
