The box is 19" tall, it will be for 2 12" L7's. I made this box before but not sure how long I made the short port peice before, the old box was stolen. The ports are 2 1/4" x 17 1/2". I had L5's in the last box like this and liked it (prefer low end bass). I'll be building it this Saturday, and probably as drawn, but would like to know for sure what the tuning is so when people ask.

Here's a front view of my last box, which will look exactly like the new one
