Very nice build dude, i´ve seen all of your builds actually, i was considering building a flat wall just like that in my EX, but, i DD´s doesn´t like "small" ports at all, you managed to get around 335SQ of port with the flat wall, honestly speaking, that doesn´t work for my 3518´s (unless i´m doing something wrong haha) , that´s why i´m going with a 6th order in the future i guess, what´s the shell dimensions ?if you don´t mind me asking
