I need to raise the tuning to 33 or so, but I need at least 30sq in of port area, how much should I take off the end of the port?

That should be pretty close to 33hz. The net volume will be about 3.35ish though but it really should not make a difference.

hmmm... weird I used http://www.reaudio.com/speaker_box/LPort_Box_Calc.html

and it say's the 2nd port piece should be 3 in long for a tuning freq of 33hz with 3.9cf

edit: btw this is for a RE Destroyer 15
