my question is if I am building a vented box for a sub and the recomended port size is say 2" x 16" rectangle and 38 inches long. Can I make 2 ports 2" X 8 " rectangle both being 38 inches long sense the 2 ports will both have the combined area as the recomended 1 port will in the specs (32 square inches) and get the same results for the selected tuned freq? And for question #2 If the recomended port size is 2" x 16" (32 square inches) would it not have the same result if I used a 4" x 8" port (32 square inches)? I Just want to know what my options are and if these variations can be used and get the same result as the recomended tuned enclosure specs. As far as my knowledge goes the main thing is the area and volume, and area and volume has no shape.
Any info from some box pros will be helpfull
