[QUOTE="nismboy6986, post: 742161, member: 543960"] 1. can you go over that nine to 1 ratio jl talked about on thier tutorial. my port would be 2"x20" would that be good? 2. to find find the physical length of a port you would just make a imaginary line that goes through the center of the port and stays going through the center of the port and measure it. 3. to factor in end correction i would just take half the width of the port, in my case 1" and add that to length of said imaginary line when figuring out the length of the wood that would make that wall. so i would make that piece of wood that makes the port 1" inch longer than it would be if i just went by that imaginary line when i compensate for end correction. and since i rather "grasp" info that just go with it what exactly does end correction account for? the bends in the port and the fact that the air isn't going to turn around exactly at the inside wall of the port in a bend or what?
