Hoping korey will chime in here, but anyways, So as you know, I posted lots a q's about diff box designs etc. but today we started building my buddies box (as seen below) and his port is 9.75" tall and 12" wide, I enter in 26" for the length, and I get 15.5" for the physical length, there is an 10.5 inch difference between the port length and physical port length, is that due to the shape of the port? It has 1 common wall.
(Yes pen and paper is best, but I'm not to that level yet)
Gives me 8 cubes after displacement, 14.63 per cubic foot and tuning of 31.47hz I had very good luck with my sp4 box using the physical length, along with my dads type r box, but the end corrections weren't this big, is 15.5" the right length? Cause it says the port does bend also.
Thank you in advance.
