I tried my hand at designing my ported box for the MAW 10 that will fit behind the seat of my RCSB truck. I have decided to go to 1ft^3 as it recomended to keep things comfrotable. According to my figures using the formula on JL Audio site I reached these figures. Port is a piece of 4" PVC. Box @ 1ft^3 28" port 33.08 Hz 27" port 33.63 Hz 26"=34.20 Hz 25"=34.81 Hz 24"=35.46 Hz Is this right and which one would should I go with for my purposes as a daily driver? And also what should I use as the displacement for the driver? Thanks for yalls help in advance, Aaron
