1.83 ft3

/2

0.9ft3

3x2.75x20 /12/12/12 (rough estimate of port area)

0.1ft3

sub: 0.05ft3 (typical)

0.9-0.1-0.05 = 0.75ft3 - but actually slightly smaller because I didn't take into account the separator board in the middle.

I ran both volumes through WinISD and there isn't a massive difference between the two. It will work. At .75 the box is tuned a few Hz higher.

Ok I get it, You get the same .89 or .9 BUT i did not remove the port area... lol i get it. i am so dumb sometimes. Sorry for being such a dummy. lol
I was a bit lost in the program on where to enter all parameters for the box though.
