Well im getting ready to build a box for a single 12" L5 and had a couple of ?'s. It's going to be 32 wide 15 tall and 16 deep. I figured a 3" port and a 14" second wall port that gives me 2.7 cubes tuned at 33, port length of 31.5 and 40.5" of port. Does this sound about right? I figured a wider port would be better but it sky rockets the tuning and not sure how to get it back down.
