Port area for FI Q 12 d2

[wrldzmyn 0]

My enclosure is built at 2.5 cuft, my current port area is 10x4x21, tuned to 39 hz, I want to change this so its tuned to 32 and I would need to add 14 in in length, unfortunatly not possible. So I looked into it and I could change my port to 10x3x25, what will I lose(or gain) by changing the port area ?

Nothing. 30 sq. inches of port should also be just fine for that sub.
