I used this link to figure out my enclosure's dimensions:

http://www.reaudio.com/speaker_box/LPort_Box_Calc.html

It says that using the following measurements:

Box Width: 36"
Box Height: 15"
Box Top Depth: 18"
Box Bottom Depth: 18:
Using .75" MDF
Square Port 1 Width: 4" (the port opening's width)
Square Port 2 Width: 6"

that the enclosure would result in the following specs:

Gross Box Volume: 3.627 Cubic Feet, or 6267 Cubic Inches
Tuner Frequency: 35.36

Can someone please double-check these measurements to verify the accuracy of the results? I'm shooting for around 3 cubic feet net volume, because I am putting in 2 subs with displacements of .25-.3 cubic feet/sub and am shooting for ~35 Hz.

Will only having one port be okay when I have both subs in?

I like this site better than RE's calc..... http://www.subwoofertools.com/forum/ported-box.asp?Ew=38&Eh=15&Dia=6&Xmax=16.5&Vd=.1&NumW=2&Vb=3&Fb=32&Qts=&Vas=&Fs=&CE=1.5
P.S. The box that is there is just something I was messing around with. Good luck

Just read the last part "having one port ok?", and yes one port is fine.
