4 aeroports enough?

[htownplaya456 10+ year member]

Hey I'm designing the new box for my brothers truck for 4 Arc Audio ARC10D4's and was wanting some other opinions on if you think four 4" aeroports will be enough or should I do 5? I originally wanted to do four 6" aeroports but they are a little bit more pricey than the 4" and didn't really have the space to do them. I can easily fit four of the 4" in the box and can get five in there if I really need to. Anyways any opinions are greatly appreciated.

How much of an audible difference would I hear from doing 5 over 4?

what really determines how many or how much port you need would depend on internal size of the box. not so much drivers

Well the internal volume will be dependent on the amount of ports I do. Since space is limited I have 6.75^. The current I have is 5.8^ net with four 4" aeroports tuned to 32hz so they are each like 13.75" long. Then I have Driver displacement and bracing... lots of bracing.

Just because most people base their port area on CF doesn't mean its supposed to be.

It should be based on driver displacement.
