Okay, ive run into a HUGE problem designing my box. My hatch area is UBER shallow... which means my box will have to be under 14 inches, and if i make it long itll have to be 12 inches for the hatch to shut. gay. So my box is gonna be 12 inches. Gay. The box dimensions are gonna be 12"(tall)x30"(wide)x20"(long) That means that instead of having the drivers and the port facing foreward or the drivers facing foreward at all is not an option so ill have to make the drivers face up. Thats not a problem. The problem comes with designing the port. I was shooting for a slot port facing foreward ont he bottom side of the box. The calculators i was using warned against the height:width ratio as the port would have been like 28.5"x3 or 4"... and the port would be like 40 some odd inches long... which i dont have room for unless i build a snail shell box... which isnt TOTALLY out of the question just yet, but the driver depth would be an issue. SO I thought i could build a box with the drivers facing up and a slot vent on the front of the box with the slot vertical on one side of the box... measuring like 4"x10.5" tall. That seemed to work.. except when i went to draw it up on graph paper.. the box isnt wide enough for that. So im thinking about round ports but i know next to nothing about tuning with round ports... can i get some help with these ports?
