Can someone plot this sub for me in WINISD?

I keep trying and trying and it doesn't seem to be working right, it is giving me only .17^3 for sealed and .30^3 for vented with a 70 some inch 3" port. I am at my wit's end and could use a little assistance since I seem to be dumbfounded here.

Thanks!

they are optimized for tiny boxes....tune 37-40

How do I get 70 inches of round port?

seems a bit far fetched to me

I have another program that does boxes....let me consult it

I thought maybe the box size was okay but the port area seems way off. They are figuring the .37 I need as net after port and subwoofer displacement right? I have quadruple checked that I entered all the specs right and everything is good there. Just getting a whacky port result is all.

other program says to do a ~.3 ft^3 box with a ~2 in port ~18" long

seems like a biatch

No actually it is saying .30^3 for ported tuned to 38hz, and to get the vent mach in the green the smallest round port I can use is 2.3" and still has to be 23.28" long.

WINISD says I go 2" x 18 but vent mach is red. It would have to be external port, which is okay I guess.

nets a .12 vent mach.....this is OK depending on what you want to do with this

do the .18 sealed after sub displacement and you won't have to worry about the port mach

I am thinking of putting in the backseat of my beater S10, so cosmetics matter not, just needs to sound good. So one could potentially just basically put the port entirely outside the box in this situation.

Well my concern with a single 8" sub is output, trying to get the most out of it by porting it, and I won't have a ton of power for it either so efficiency is also a goal...

could.....yes

Thanks for the help, I am going to go sleep on this and maybe it will come to me. Thanks!!!
