I finally got through with my box for a 13kv2 for my silverado regular cab. I went through about 5-6 designs before I finally got the one here. It is a slot port that 1.75'' x 12.5'' giving it 21.875 sq.in. of port area. The port is 38 in. long and the box volume is 1.5 cu.ft. giving it a tune of 29 hertz, give a hert or two. Well here are the pics.
Just an overall shot of the box. I know the wood putty is ugly but I'm gonna carpet it.
A shot of the port. The left side of the port opening (which cant be seen in the picture) looks like a just a hole. This port bends immediately to the left causing the left side of the port only to extend down 3/4 in. It may sound wierd but the port is even all the way through even if it doesnt seem like it would be. It's like a bend in the port on the long side of the port instead of the short side, if that makes any sense.
Here you can see the port from inside the box. The center of the box where the port opens is to the right. Far back in the picture is the left side of the box with the port making a bend back toward the center of the box with the end of the port inside the box having to be sanded to an edge to clear the front baffle. Very tight fit I must say.
So give me some opinions on my box i designed and built. I can't wait to get my 13kv2 at Christmas!
