tunning help!
ok so im guna be building a new box that 7.3 befor displacement i have 4 6 inch sono tube ports here that are 24 inchs long
how long would all 4 of them need to be for a 38HZ tune? im told they would need to be over 50" long is that true?
i was told to run 3 at 22 inchs long and that will get me to 37.5hz

Yep, looks like 3 @ 20in gives about 6.3cuft after disp tuned to 37.5ish or 4 @50in gives you 3.7 after disp for 38.16hz tuning. Obviously 3 6" tubes wins. lol but it's only going to give you 12.85sqin of port per foot of air. Might run into port noise issues with the power you have.
4 6"x 34" long will get you tuned to around 39.25hz but still only leaves 5 cuft after disp. This gives you about 22sqin of port per foot of air.
