I have been reading on t-line boxes for a good 2-3 hours now and am just not understanding the design part 100%. Only one that I have read and felt like I somewhat understood was the "u-shape" style design. I have always done slot ported boxes and was always happy. I think it is time for me to learn a little more about boxes.
So far, this is what I have grasped
Say I wanted a box tuned to 34hz. I would take 1130 (the speed of sound,) divide that by 34. Which would lead me to 32.25ft (rounded a tad). I would multiply that by .25 because I am looking for the 1/4 wave length. I would need a port 8.0625ft long. I know sd comes in to play somewhere around here but am not sure how or why.
If any one could point me in the right direction or let me know if I am even on the right track would be great.
The box I will be designing is for a single 10 nightshade v1
