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

 

What are your max dimensions when you calculated that area?

 

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. GL

 

im going to try the 3 6 inch ports out see how it works box building day!!!!!!

 

What woofers do you have going in the vehicle?

 

so does the port tuning calculator work like the one found at 12volt.com wut i mean is how accurate is it? and just for argument sake pretend all the calculations are correct (displacement)

 

ok i had to make hte 3 6 inch ports 17 inchs long box is tuned to 39 hz roughly should be half decent car seems to peak at about 42-43 so shoul dbe nice around there haha

it will be a single old school stroker 18

 

Over 6 cubes for 1 stroker? WOW.

 

They have always performed well in large enclosures. How are you gonna put it in your cav? Sub up ports back? What r u powering it with? It should definetly ****.
