Yea I got new measurements... But that online ported box thing hates me... It assumes the width is also the length, which isn't true in my case!

Klown could you calculate it for me? 20 high by 20 deep by 40 long... It should be like 7.125cu/ft and I'm gonna tune it to 30hz I think...

are you using 1" mdf? if so here are your new measurements cause the last ones were for 3/4"

this one is 5.6 cubic feet and tuned to 31.8hertz with your final OD measurments of 20x40x20

bottom 40x20
top 40x20
left 19x18
right 18x18
back 40x18
front 34.5x18
port 1 13.5x18
port 2 8x18


make sure you port width is 4.5"


and port 2 is the second part of the port its a two piece 'L' shaped port

I think the box'll need to be bigger than that... Can you add depth? maybe up to 23"?
