    T-Line help and pointers

    Why do so many people use them if they are only marginally better then a standard sealed box? Seams like a lot of hassle for something that can be had with a simple sealed box. I am not questioning your knowledge only trying to learn for myself.

    T-Line help and pointers

    I never said anything about it having a port, am only trying to learn how to design one and learn how they work....nor am I comparing them to any other kind of enclosure, simply want to understand them. I know there is no way to have a true t line in a car due to size.

    T-Line help and pointers

    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. And SD equals port area? Also I am aware this is not a full t-line, hence why I am asking about 1/4. 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
