The pain in the ass of doing the internal bracing. I'm just not very good at building stuff; even with instructions, it always comes out wrong. I am going to build the box slightly bigger than I need, and then I can use acousta-fill or pillow stuffing to bring the volume down as needed.

What I need as finished product, though, is 9.3 cu. ft. of air, and 3 four inch ports 25.59" long, so that the box is tuned to 19.8 Hz. This is for an 18" home theater sub.
