i'll give you the bassbox pro calculation. its usually off by 1-2 Hz., but hardly audible. i'm much too lazy right now to do it properly.

and what should your port area be?

and what the hell was wrong with your glass box?

Go for 25in^2

with the dimensions above, i got a port length of 26.14, width of 1.75, and height of 14.5 for a tuning of 30 Hz. This brings the volume down to 2.79 ft. ^3. this was all done on bassbox pro, so it may be off by 1 or 2 Hz. (Its usually higher than it really is, so its probably somewhere around 32 Hz in reality). hope this helps.
