Need Help With Design

[Crump]

I want the Port in the middle of two 12" subs. I have no idea how to tune it, I used the Re Box Calc for my box. But it was a L ported box. I want to have the two subs like face toward the middle and kind of up. So it's a ported Semi-glassed box. So any links? Or is there a way i can use that box calc

you can still use the port calculator as long as you're pretty good with math and can figure out the volume of it.

have you looked into aeroports?

much easier to build a glassed box with aeroports and tuning is alot easier IMO
