Round Precision Port diameter?

ive heard that technically you only need roughly half the port area using aero ports compared to slot ports.. 1 4" should be ok then?? tommyk, what would you suggest for 6cf with 2 15"s? (nightshades) 4 4"s for daily?

It's better to go with less larger ports to reduce the surface area, reducing noise. Like tommyk said, try three 6", but if they end up too big, two 6" would work just fine.

2 6's is more port area than 4 4's anyways. I recommended 3 6's because that's what we used on one of my teammates boxes with two MT 15's and it wangs.

You can also turn the port inside the box using pipe elbows.

I don't have much room to work with. That's why I'm thinking round flared port as opposed to slot port as the slot would displace a lot more space. I think I may try it out with 1 4" and see what happens.

Ya 2 cubes, with a 4" aero will be fine on space constraints. Just get either a 90* or if you can a 45* elbow and use that.

what would be a safe clearance between the back of the box and the end of the port? 2"? 4"?
