8 cubic feet box + port @ 34 hz

[sorizaga]

HI everyone, I know most of the builds are done with high powered systems and high quality subs.

I will simply start working on a new box for 3 15" kicker CVRs this will be on a chevrolet truck

basically its a blowthrough set up.

here is the old box

my plan is to do a box for the 3 subs that is one big chamber

Right now I have this box diagram or drawing that I have started for 8 cubic feet + port (110 sq inches) @ about 34 hz.

anybody has a suggestions comments for the port area or tuning freq given that I will be having 3 15" kicker CVRS on this 8 cubic feet box

The main question will be here what will be a good port size for 3 15" kicke CVRs subs they dont have that much of excursion , about tuning I can handle it

but the main thing will be the appropiate size for this mentioned port.

Meade has 120 square inches of port area for 4 18's with subs that have tons of excursion xmax 30 mm or more.

But then I have seen set ups with only 2 subs with as much as 150 square in for port.

well any ideas are greatly appreciated.

once I get set with this port stuff, I will surely start the build with pictures and everything here.

Thank you all

I hear 15-16 square inches of port for every cubic foot you have.
