U guys have come highly recommended

holy s#*t.  i should of stayed in school.

o.k. so lets see if i an=m getting this right.  i like the idea of one rectangular port in the middle, seperated by the baffle, cause this would also add strength.  is this right.  i am working on another drawing right now to show you guys cause i would like to be sure that i am on the same page as you guys.

thanks

something like this.

and this

these are the measurements(outside) i have so far for each box:

16" high

16" wide

22" deep

=2.26852 cubic feet.

as for the size of the port. i am still a little iffy here.

jbl says 4"diameter x 13.31"  (30hz)

so if i make a port 1.5"wide x 8.9"(8 7/8)deep =13.35  is this correct. if so how high shoud the port be, or am i missing something here.

Box size =

Port size =

The port length will remain the same at 13.31"

The port diameter tight now is 4". So using the formula I posted earlier shows this.

So 3.1415 * 4^2 = 12.566 in^2

Find and two numbers that will now give you this measurement.

Say 1.5 * 8.37 This would be the internal measurement for the length and width of the slot port.

alright round three.

i hope this is right, if not i am feeling really stupid.

Yes!
