I'm going to try to build a box by this weekend as winter is near and the snow is very near! It's going to be for 2 RE SX12's. Box needs to be 3.2-3.5 after displacement. Subs displace .3 so keep that in mind. I want the width to be 36" and height to be 15". I can go to about 19" on depth. Tuned to 35hz. Cut's can't be crazy either since I'm limited on tools and the jigsaw would be my best friend. I want something like this and the kefered part of the port would be done with fiberglass/kittyhair or something like that. I don't need an actual box, just a design... for cheap please. I'm not trying to spend $50 on a design and have to buy everything to build it too when I can have this built for about $100.
