Port area for RD Alpha 18

[DNick454 10+ year member]

Well, I just watched a build for 6 18's. And it had just a hair short of 500 sq in of port area, so thats around 85 sq in of port area per sub. I would definitely talk to that guy and confirm all numbers and whatnot.

sounds like you already made up your mind why ask for help?

why does it sound like that ? because ive tried what he suggested before and it worked well ? you assume too much, i am just trying to figure out why more than a few people are suggesting 12-16 per cube , maybe il try and see, although it would be a waste of 1"mdf if its wrong
