Ok I am doing a box for 4 fi ssd 12's. It will be 8 cubes after displacement. I need help with the port tho. I am wanting to tune to like 35htz. I kinda want to try flared aeros but don't know what size or how many. Can someone help me out. Also need help with the length

i plugged that into WinISD and it looks like 4 4" aeros at 10.6" long would give you the desired tunng with a very low port velocity. you just have to remember to not count the flares when measuring the port length

you could also try 2 6" aeros at 10.85"

So I would just be doing a measurement inside the flares?

hope this helps

and heres a link to the site i got that from

I am way to tired to understand all that lol. Have you ever used aero's or built a box with them?
