[QUOTE="cha0, post: 3009863, member: 571056"] yea, like i said before im toying with the idea of aeroports but i dont get this shit. im on PSPs site and im looking at there calculator. Volume of Box in Cubic Feet 2.5 Tuning frequency 40Hz Port diameter 6 inch port Number of Ports 2 the out put tells me i need a straight length of 33.71 (im assuming inches as it dosnt say) and a flared length of 34.71 now if i change the number of ports to say 6, the lenght should go down becuase the more ports you have, the more port area, the less the lenghth should need to be to get the desired freq. so lets try it. 6 ports gives me... 71.81 straight 72.81 flared how does it need double the lenght if you are doubling the number of ports. all common sence tells me that the lengh should be cut in half if you double the amount of ports...? what the hell am i missing? AND BTW, what are the 2 different numbers for? is the straight number the lenght of just the pipe, and the flared number how long it is after the flares are on? so basicly the flares add one inch of lenght?
