Default Aero port help

Hello all I am in need of help with a new box design.

My requirements are 6-7cuft net volume, gross volume can be adj accordingly. 27-30hz tunning on x amount of 6"(or different) aero ports by x length. This box is for 6 dc lvl 3 10s on 6300rms. 20-25" in length for ports before bends are needed.

I have tried so many calculators and can't for the life of me get a straight toward answer as to how much port area I need for this box and how many ports, length, etc. one contradiction after another. I'm amiss with this and anyone who can give me a good educated answer to my conundrum would be greatly appreciated.

6 cubes @ 27 hz w/ 1 x 6" = 13.03" straight port or 14.03" flared.

2 ports would be kinna crazy in length.
30.05" / 31.05"

1 x 8" aero at 27hz would be 26" flare end to flare end.

A single 8" is all you need.

Thank you very much, my only question when I was thinking of just one aero port is port noise since the one is only 28.27in^2, so vent Mach is 135.7m/s, would this not create alot of port noise?

There is a guy on here who makes kits. I would tune to 30 hz which would be 20" from flare end to flare end.

Hmm if I'm right that one 8" port should have a vent Mach of 76m/s, do u think that would be making much port noise, would love to have this as clean as possible.
