I just built a box for my alpine swx 1242d. The boxes dimensions are 13.5H x 25W x 15L using 3/4 in. MDF. And I'm putting a slot port in on the left side of the front peice. So my port would be the height of the box. I want to tune it to 24Hz. This is my first time tuning a box and I'm a little confused and I want to do this right so any help would be really appreciated. How wide should I make my port?
