Ported box for 4 RE8s, numbers sound right?

[JeffyZ33 10+ year member]

Well I ran some numbers last night, and I'm wondering if anyone who has a program would like to put them in to see if I'm about on target.

Here what I came up with:

*Truck type box, with a flat top*

---ALL OUTER MEASUREMENTS---

Height-19''

Width-35''

Top depth-5.5''

Bottom depth-11''

# of ports- 3

Ports - 2 1/8 outer diameter, 2'' inner diameter, 10.95'' long each

After that I should come up with just about 2 cubic feet after all displacements and tuning @32hz.

If someone could run these numbers and tell me what I need to adjust that would be great. Thanks

So i realized my dimensions are confusing if you dont know the type of box i'm talking about, so here we go.

All dimensions are OUTER.

3x 2'' inner diameter, 10.95'' long each ports isn't enough?

9.5 sq in of port for 4 8s? i dont think so lol.

Maybe I'm doing something completely wrong with my calculations.. but could you please tell me how you get that little of an area.

There are 3 ports

2'' inner diameter pvc and nearly 11'' long each

Total that's 33'' x 2'' ID

I've been told 9.45" each, does this sound good?
