I have enclosure plans that call for four ports, 2.38" ID x 3.5" long. I was playing around with the AJ Vented Designer application and came up with these alternatives using two ports instead of four:
1) 2.38" ID x 0.88" long
2) 2.75" ID x 1.49" long
3) 3.00" ID x 1.97" long
4) 4.00" ID x 4.48" long
Does the math look right here? If yes, is there a preferred choice?
Thanks,

Bigger and longer is better for speakers with big displacement.
The disadvantage of large ports is the port area needs to be deducted from cabinet volume, so you end up with a larger box.
The port size estimates look reasonable.

The gross internal volume is 5610 cubic inches -- 34 x 15 x 11.What is the box volume?
1. 50.2Hz
2. 50.6Hz
3. 50.8Hz
4. 51.7Hz
Have you tried 'Boxnotes' and 'Flare-it'? Very handy for figuring out port velocity requirements.
